Our Story - SPD Exhaust

In 1992, after considerable thought, SPD embarked on a manufacturing course. The investment in equipment, tooling and personnel were only the beginning of what is today’s result; a successful small manufacturing company.

The company has progressed from a regional, to national, and what is now an international supplier of specialty exhaust components. Through it all, the company has remained family owned and focused on the goal of providing quality products and services. SPD continues to grow, keeping a pace that will

not jeopardize the standard of quality and service that our customers have become accustomed to.

In 1999, SPD was incorporated and the leadership roll in the company passed to son Chris.

Jim enjoyed all forms of motorsports but, it only took one trip in 1957 to fall in love with the Bonneville Salt Flats. In 1982, Jim & Chris began building Land Speed cars to compete at SCTA/BNI & USFRA events. The duo would go on to establish 4 world speed records in several classes and a land speed record of 307.797 mph in their V6 Buick powered Hill & Hill streamliner. They would eventually push the car to a one way top speed of 331 mph.

Jim made his last trip to Bonneville in August of 2006. Unfortunately, it was after his death on June 28th. But, he did get a ride at near 200 mph in

the SPD 1929 4 wheel drive roadster he had originally designed & built.

Jim had been battling complications of diabetes and heart disease for years but it wasn’t enough to keep him away from doing what he loved. He worked till near closing that Tuesday before his passing and shocked us all when he didn’t wake that next morning.

He is and will always be sorely missed.

He was my Father, my partner & my friend.

The roots of SPD go back to the late 50’s and the booming Hot Rod industry in the Los Angeles area. Jim Hill was a schooled engineer studying Mechanical Engineering at Cal Poly-San Luis Obispo. In 1959, after marrying his wife Peggy, and settling in Van Nuys, CA, Jim began work in the exhaust industry installing mufflers & exhaust systems for Sepulveda Muffler in the San Fernando Valley.

In 1963, Jim opened Exhaust Engineering and began designing & building custom headers & exhaust systems for racers and enthusiasts in the area. The business was a success and helped him further his trade.

From late 1966 thru much of 1968, Jim worked for Tom Patterson Enterprises (of Patterson Oil Tanks) and Nelson Tyler Enterprises. While working with Nelson Tyler, Jim was involved in the “Rocket Belt” project, as flown in the opening ceremony of the 1984 LA Olympics. He was also involved in the construction of the first passenger cradle on a Helium blimp & aerial camera mounts used on helicopters to film any event from the air. Jim was very proud of his involvement in helping pioneer these now commonplace tools of today’s movie & sporting events.

In late 1968, Jim was offered a job managing a new division of Cragar Industries called Saber Manufacturing. Saber Mfg. was the subsidiary that manufactured the old “Cragar Hotpipes”. He successfully managed Saber and enjoyed the constant weekend trips to the races while working for Cragar and learning all he could about the exhaust industry.

In 1973, after tiring of the commute from Van Nuys to Long Beach each day for nearly 5 years, Jim took a job in Northridge, CA with Torque Engineering. Torque was a motorcycle exhaust manufacturing company. Twenty minutes from home each way, Jim enjoyed his new job and would successfully manage the manufacturing side of Torque Engineering until his big move north.

In 1976, Jim and his complete family moved to the Sacramento area. Although SPD had begun as a moonlight business in 1969, Jim decided to continue with the name Specialty Products Design and renewed his self employment journey again. The business would continue to grow thru his hard work and perseverance. Later came the addition of Jim’s son Chris who would become a partner in the business. The two would establish a reputation in the area as the place to go if you wanted it done right.Over many years, SPD has designed and built components and complete exhaust systems for all forms of motorsports. (cars, boats, motorcycles, even airplanes). The family’s continued involvement in racing has helped keep them up to speed with the rapidly evolving technology.

Header & Exhaust Systems

Merge Collectors

Merge Collectors have been used for many years in F1 and Indy cars. The technology has trickled down into almost all forms of professional racing. Today they have become common place and in competition, merge collectors are used wherever rule books allow.

Cut-A-Way Views

On pages 3 through 15 you will find information on merge collectors to help you decide what type is for you. If you need more help give us a call or fill out the vehicle specification sheet available online.

Getting Everything You Can (Out Of It)

If you are not sure of your header and collector design, please fill out the vehicle specification sheet available online and send it to us.

The exhaust systems role in increasing engine performance centers around improving volumetric efficiency. Volumetric efficiency (VE) refers to the ability of an engine to intake and expel gases (i.e.: air/fuel and exhaust gas), in relation to the actual pumping volume of the engine. Free flowing intake and exhaust systems help an engine to achieve this. Achieving greater than 100% VE is done in part by optimizing exhaust gas scavenging to draw out exhaust and bring in air fuel mixture during valve overlap. As the piston reaches the top of the exhaust stroke, it dwells as the crankshaft sweeps across the top of its stroke. This is where valve overlap occurs. Before the piston reaches Top Dead Center, the intake valve begins to open. The trick is to design the exhaust system so that the exhaust pulse (pressure wave) leaves behind a pressure drop or vacuum to take advantage of the valve overlap. If successful the combustion chamber will exchange residual exhaust gases for a fresh air/fuel mixture before the piston has any real effect on the intake charge.

To design a successful exhaust system or tuned header, the tube size and length are selected based on a list of engine specifications and application characteristics. The tube size controls the speed of the exhaust pulse, too big and the velocity (energy) is lost. The tube length is all about timing the pulse to synchronize with the cam in a specific RPM range.

At the collector, the timing of the pulses is crucial to scavenging. Imagine a four lane freeway on ramp merging into one lane. If you get the timing and speed right, the pulses draft each other like stock cars at Daytona, increasing their speed. This is where the Merge Collector comes in. It makes that transition from primary tube to exhaust pipe as smooth as possible. This reduction in turbulence helps maintain velocity through the collector, thus increasing the scavenging power of the header system.

(MC) Merge Collector

(WMC) Weld-On Merge Collector

(FMC) Flat Merge Collector

(BMC) Bent Merge Collector

DSMC’s are used primarily in turbo applications where the benefits of a true merge are needed and a removable collector offers the best design solution. The double slip receivers provide the extra seal necessary to prevent the loss of exhaust manifold pressure.

WMC's are primarily used in turbo applications where space constraints are the biggest concern. The WMC’s form is like that of a formed collector but, is constructed like a merge collector to provide the material strength necessary to withstand the stresses of a turbo application. WMC’s also allow for the use of a smaller outlet size than is possible with a formed collector.

The traditional merge collector can be used as a removable piece or welded. Pre-bent tubes are machine cut and hand fit to form a pyramid inside each collector for proper airflow management.

This FMC style collector allows for maximum ground clearance. Applications include street rods and transverse mounted inline 4 cylinders and flat opposed 4 or 6 cylinders.

Building a tuned header in a confined space can present some real challenges. The BMC is designed to help solve some of those problems that can arise when building a Tri-Y system. Rather than compromise tube length, this part allows you to place the primary or secondary 2 way collector while changing direction.

Merge Collectors StylesMerge Collectors Styles


Merge Collectors are a common choice of professional engine builders and race teams. Pre-bent tubes are machine cut and hand fit to form a pyramid inside each collector. Merge Collectors are TIG welded to ensure professional performance and appearance. SPD Merge Collectors are cleaned and polished inside for maximum flow.

Standard Merge Collectors (MC)

Merge Collectors can be ordered to collect as many as 6 or 8 header primaries, although we usually don't recommend this practice for competition engines. Two, three, four, and five into one collectors are better at preserving the velocity of the exhaust pulse as it transitions from the header primary to the secondary exhaust. Every tube added to the collector requires an increase in the outlet size. With a larger outlet the exhaust pulse will become defused, losing some of its velocity and reducing the scavenging effect of the header. The relatively small minor diameter of a 2 into 1 collector maintains the focus and laminar flow of the exhaust pulse. This is one of the reasons 4 - 2 -1 or Tri-Y headers are effective.

The convergent angle can be selected for maximum performance or minimum length.Shallow angles such as 12 and 15 degrees offer the greatest performance gains.

If lack of space is the biggest concern, a 20 or 25 degree collector can save you an inch or more.

We stock unfinished collectors and collector bends from 1.25" to 3.50" OD. This allows us to ship the same day or within 48 hours in most cases. 4 into 1 collectors from 1.25" to 2.75" are standard items.

Minimum outlet size is typically one tube size larger than the inlet size. 15, 20, & 25 degree collectors can be ordered with outlets the same size as the inlet (example 15200-4-30418 with 2.00" outlet).

Maximum outlet size is typically less than 2 times tube inlet size. 12 degree convergent angle required for maximum outlet size (example 12263-4-30418 with 5.00" outlet).

Our merge collector part numbers have no reference to an outlet size. You will be asked for the desired outlet size when you place your order.

For naturally aspirated engines, the idea is to reduce the minor diameter to the point just before it produces a negative effect on peak power. This produces the broadest power band. The relationship between the inlet and outlet size is based on the frequency of the exhaust pulses. Compared to a stock Honda 4 cyl's peak RPM of 6800, the exhaust pulse frequency of a F1 V8 @ 18,000 is nearly 6 times greater. For this example the Honda may only require a minor diameter two sizes larger than the primary size and the F1 car would have no restriction.

In the case of blown or nitrous oxide injected engines the objective is to have little or no restriction.


Standard Merge Collectors (MC)

Double Slip Merge Collectors are used primarily in turbo applications where a removable collector offers the best design solution. The double slip receivers provide additional inlet sealing, helping to prevent the loss of exhaust manifold pressure. This eliminates the need to weld the collector to the header primaries. The double slip arrangement also allows for a minimal amount of torsional movement during operation of the engine. All of these features reduce the potential for failure under the extreme temperature swings seen in turbo headers.

The assemblies shown below and on the next page are ordered as a collection of parts to be incorporated into a new header, not as a bolt on upgrade. We can build the sub-assemblies or a complete fabricated unit as in the case of a welded Tri-Y, but we will need more information that just the inlet and (final) outlet sizes.

Designing a Tri-Y header for a competition engine is not something to take lightly. As previously mentioned, if you are starting from scratch it may take a bit of R&D to design the ideal Tri-Y. There are

more variables then you have designing a 4 into 1 system. Choosing the wrong size or length can be more detrimental. We have a lot of experience with Tri-Y’s and may be able to guide you in the right direction or suggest a design for a common engine combination.

Tri-Y header designs started as a way to build torque in a simple truck and RV header. In

recent years, it has been tried in some of the most unlikely racing vehicles and proven to be an effective design for almost any naturally aspirated application. The benefit

is a broader power curve, producing more average horsepower over a given RPM range, resulting in lower

elapsed times. With enough research and development a Tri-Y header can reach this goal without sacrificing horsepower

compared to a 4 into 1 design. For many applications, the costs out weigh the benefits. For some, like a Bonneville racecar, any loss of peak

power is too much. We typically recommend Tri-Y’s for road racing, off-road trucks, and circle track cars. All of these vehicles are relatively heavy and require a

wide usable RPM range.

When Ordering Specify Welded Tri-Y headers offer the same benefits as the slip-together but without the adjustability. Once you have settled on a design, a welded Tri-Y can be built to the same specifications as a slip together. The advantage is reduction in weight and/or space. This makes it a good choice for applications such as midgets and motorcycles as these are huge concerns.

Balanced Exhaust

SPD 's most popular crossovers are made from 1 D (1 x Diameter.) Radius 90 degree bends. This compact configuration is ideal for most V type engines. The bends are welded together around a common port. This helps to equalize the pressure between the left and right banks of an exhaust system without sacrificing volume. A stiffener plate is added to each side to help support the weld around the merge.

Most naturally aspirated engines with dual exhaust will benefit from some method of pressure balancing. V8's in particular have an unbalanced firing order, such as the sequential firing of cylinders 5 & 7 on a stock Chevrolet engine. This is what gives a true dual exhaust system its signature rhythm. The uneven back pressure will disrupt the scavenging pulses utilized in tuned exhaust systems. There are several design strategies employed to rectify this problem; 180 degree headers, 2 into 1 merges, H-Pipes, Crossovers / X-Pipes.

WMC’s start life as a Merge Collector with a specific centerline spacing. The bends used are one tube size larger than the primary tubes on your application, allowing them to seat just inside the collector (about .18" - .25" deep). After assembly, the straight section is removed as well as the center pyramid.

A Shorter Length is the biggest advantage of a Weld-On Merge Collector. Compared to a standard Merge Collector (see example right) the WMC is much shorter, making it easier to package in the confined space of the typical turbo charged vehicle.

Customized - Unlike stamped / formed collectors that have to be retooled to change their shape, WMC's can be custom tailored to fit your design parameters with different convergent angles, outlet sizes, and inlet centerlines.

Material - When ordering WMC's you can chose from three different material types: 1008 Mild Steel, 304 stainless or 321 stainless steel

Street Style WMC’s are designed for header tubes that are collected together with a net fit (no clearance). This makes them easy to assemble.

Turbo Style WMC’s are built with a slightly wider centerline. This leaves a gap between each of the header pipes allowing for expansion. Use shims to maintain this spacing when welding the collected header tubes together.

► Standard bellows are typically used somewhere between the header collector and the muffler to absorb axial movement (engine and chassis flex)

► Not recommended for use in pre-turbo plumbing.

Features & Recommended Usage

► Limited angular flex. Not made for extreme axial movement.

► Slip Joint bellows are designed for use in high temperature and high pressure environments.

► 18 gauge 321 SST internal slip joint provides a smooth surface for directional flow.

► 625 inconel accordion style bellows absorb linear growth caused by thermal expansion.

At SPD, we start with the highest quality tubing available for automotive exhaust, CREW-AKDQ carbon steel and 304 stainless steel - A269 specification. (see pages 28-29 for more information). This material comes from the most reputable sources in North America. Sizes 1.25" through 3.00" are all bent in house by our experienced staff, on one of our two mandrel benders using well maintained tooling. This insures consistency in the products we offer to our customers. Because of this consistency in our materials and process, I like to say "We know what our bends will look like before we bend them". We are confident you will be satisfied with the quality of the product you receive. You can be confident that on your following orders, you'll know what the parts will look like before they arrive.

1008 is an ASTM grade of carbon steel. Composition is 99% iron alloyed with manganese and carbon. It is characterized as having excellent surface finish and formability. To provide our customers the highest quality bends most of the mild steel tubing we stock is made by the following processes:

Cold Rolled Electric Welded or (CREW)

Aluminum Killed Drawing Quality or (AKDQ)The aluminum is used to remove oxygen while the steel is in a molten state. The resulting steel is more uniform, less prone to corrosion, and easier to form (draw).

Flash Controlled - Flash refers to the raised seam of the weld running the length of the inside of the tube. Flash Controlled tubing has that seam reduced to less than .010".

.060" - .065" = 16 gauge

.045" - .049" = 18 gauge

.030" - .035" = 20 gauge

304 is the most common grade of 18/8 stainless steel. The 18 & 8 refer to the percentage of chromium and nickel respectively. The chromium forms protective oxide layer on the surface of the material, which is why it is characterized as “stainless or corrosion resistant. This property is not just skin deep as with coated metals. It has excellent forming and welding characteristics and can be polished to a mirror finish. All these properties have made it the preferred material for all kinds of fabrication.

A269 Specifies the requirements of an annealing or heat treating process referred to as "bright annealed" meaning that it is free from scale. On its journey from ingot to tube the material is work hardened and overheated from welding. The treatment restores the material to its original grain structure, reversing the adverse effects of the manufacturing process. The resulting material will withstand more elongation during forming / drawing procedures.

321 is basically 304L with Titanium added as a stabilizer to extend its heat range and improve its already excellent weldability.

At temperatures above 800°F / 425°C. 304L is susceptible to carbide precipitation, causing intergranular corrosion. This physical change in the material allows it to oxidize and can lead to structural failure.

In 321 the small amount of Titanium added (0.70% max.) maintains its bond with the chromium, keeping it from sweating out at these high temperatures. This is what makes it a great choice for turbo applications, rotary engines, endurance racing, and why it is mandated by the FAA for production aircraft exhaust. Although the steel industry recommends 321 for applications up to 1650°F / 900°C, we have seen reasonable service life from applications that exceed that temperature range.

347 filler rod is recommended for this material. It has a similar composition but uses Niobium as the stabilizer.

Number

Port Shapes Round ports are machined .020”-.030”over advertised size.

Other shapes are as much as .070” over nominal tube size to allow for easier tube shaping.

(1) Rectangle - Longer or taller than wide or high.

(2) Round - For stock round ports or oversized tube applications.

(3) D-Port - Typically flat floor and sides with radius on roof of port.

(4) Oval - Two sides half round. Horizontal and vertical oval.Square Oval - Made popular by the 18° Chevy, has radiused roof and floor.

(5) SAP - “Same As Port” - Flange closely matches port shape in cylinder head.

(6) Square - Nearly equal height and width with varied corner radius.

(7) Counterbored - To accommodate oversized tubing some flanges have a .150” deep machined step.

Our "one of a kind" approach to manufacturing header flanges started small in response to the growing availability of aftermarket heads with unique ports and / or bolt patterns. With this change in the industry, it became clear that if we were going to build headers that maximized the performance of racing engines, we would first need header flanges specific to those cylinder heads. We are not the only company using CNC machining to produce header flanges, but we are certain that no one else offers more applications than SPD.

Making a pencil transfer ( Rubbing )1. Place a sheet of paper over port(s). Use tape and a hand to hold paper in place.

2. Holding the pencil’s face flat against the paper, define the ports, bolt pattern and sealing surface.A dirty finger works just as good or better.

3. Check to make sure the transfer is accurate and the paper did not slip during the process.

If you are faxing or scanning, please include a scale along with your contact information as thefax machine will shrink the image.

Verifying the Fit of Your Header Flanges

It sounds simple enough, but the variety of cylinder heads available for some applications is incredible.Here is an extreme example - BRODIX offers 21 different models of their Big Brodie heads (see table below).

That is just one of six styles of heads offered by one manufacturer.

"I need a header flange for a Big Block Chevy"

Most of these heads have unique exhaust ports. The different size, shape, and location of the exhaust ports, combined with the features of various castings, make it challenging to find a flange that properly fits the customer's cylinder head. That is why you may be asked to provide a rubbing of your cylinder head like the example shown at the bottom of the page.

Our CNC machining station is capable of very close tolerances, but our flanges are only as accurate as the information we gather from each customer.

Looks like a perfect match? Another rubbing of the same head shows how little sealing surface there is above the port.

Well designed header flanges should be light, yet strong and have proper port alignment while providing adequate sealing area. Going back fifteen years or more, a proper fitting flange was becoming difficult to find as the number of cylinder heads available increased. Most of the "off the shelf flanges" available were universal fit. In our view, starting with well matched header flange is essential to optimizing the output of a competition racing engine. In many cases a "one size fits all" approach just doesn't cut it. So SPD took the logical step of designing and producing header flanges in house back in 1999. In the beginning there were dozens and now... there are hundreds.Keeping up with all the new applications and custom ported heads has been a challenge, but it is essential to providing our customers with quality parts in a timely fashion.

A common practice for custom headers is adding a bead of Silicon Bronze (SIB) around the header tube at the flange (as shown above). This will fill any gaps between the header tube and the port in the flange and provide additional support.

See page 85 for Silicon Bronze Rod

SPD recommends welding the header primaries to the cylinder head side of the flange and surfacing the flange flat. This avoids weakening the tube where it is typically under the most stress. Positioning the weld at the gasket side of the flange allows the tube to utilize the flange for support.

SPD currently manufactures private label components and finished products for a number of companies in the automotive industry. We can work from an existing design or create a prototype for you. Our years of experience in research and development on exhaust products for the racing industry areat your disposal to ensure the best results for your finished product.

SPD can reproduce your vehicles header on the car, or from the original, as was the case with these parts.

MaseratiBirdcage / Tipo 61

FerrariTestarossa / TF250

Our NC and CNC mandrel benders are capable of bending up to 3.50” in most materials. We also have an extensive and growing list of tooling to provide you with the right radius for your project (see mandrel bend table pgs.20-21).

To make parts more cost effective and reduce or eliminate set-up time costs, we have a 50 piece minimum per tube size and center line radius.

With our Mazak VTC200-50 CNC machining center, we produce machined header flanges that meet exacting standards. We stock well over 200 different applications for OEM and aftermarket cylinder heads. Most come in a variety of port shapes and sizes and are available from ⅜” thick 1018 cold rolled steel.

If you don’t see your application in our catalog, it is possible we can machine them for you. The popularity of some applications may make ideal additions to our product line. In this case, any special programming and set-up fees can be reduced or eliminated.

½” Thick and/or 304 Stainless are available by special order.

Fabrication

The primary focus at SPD continues to be supplying fabricators and distributors with quality components. We do still regularly put those parts to use building custom headers and exhaust systems. If you are within towing distance, say 2 - 2000 miles, please call and talk to us about bringing your race car, boat, motorcycle, or street rod in for some new pipes.

With your technical drawings or simple specification (depending on the complexity of your part) we can fabricate your custom parts. Parts costs are figured at time and materials. Some parts may require fixtures.
