The PRO-FAB Oval Bend Advantage – We use oval material that has been run through a tube mill. We then mandrel bend the material using dies specifically designed to bend o

val material. This gives us a more consistent bend and a bend that is easier to cut and fabricate.

PRO-FABrication manufactures its own tubing from flat stock. This allows us to offer an extensive range of material types and gauges in a timely manner to our customers.

We specialize in exotic metals and hard to find material types, such as Inconel 625 and 321 Stainless Steel.

            
Shearing Feeding into cutter Rolling Machine - half roll Rolled tube - ejected Welding - completed

To manufacture tubing, a blank is sheared from sheet stock. The blank is then rolled and welded, using advanced equipment and a Tig welding process. The final product is then checked for accuracy. The product can then be shipped or bent on one of our mandrel benders.

We roll and weld material from 0.015” to 0.049” thick and 1 3/4"  to 3 1/2"  in diameter with a maximum length of 28”.

See charts below for diameter and gauge capabilities.

All PRO-FAB headers are built to customer’s exact specifications, whether they consist of 1 piece or 100! We work together with the engine builder to improve dyno results and ensure compatibility with the chassis and specific car design.

Daytona Prototype

After all boundaries have been established, our welding and fabrication department builds the initial set of headers using CAD models or a chassis supplied by the customer. To ensure repeatability of performance and clearance, a Jig is built for your specific header needs. We build the Jig directly from a customer-supplied header or off of the initial build if you are bringing your car into our shop.        

Ford Asphalt
We fabricate and Tig weld your headers using precision-machined flanges with a wide range of tubing gauges available to guarantee your needs are precisely met. Mandrel-bent primaries and merge collectors increase exhaust velocity and performance.

What this means for you is the total assurance that your header will mount up seamlessly for best fit and optimal performance, whether your hearder if for your race team or your own personal hot rod.

PRO-FAB headers are always finished and assembled, ready to bolt on to your (race)car.

At PRO-FAB we take pride in our ability to produce superior quality products out of top-quality raw materials.

Don’t throw out those busted headers!
It’s easier, and more cost-effective, to repair them than you think!!

Unfortunately, racing headers are much more susceptible to damage than most people think. It is often a lot more difficult to detect than a simple crack or broken weld. That's the bad news. The good news is that stainless- and mild-steel headers can often be repaired to like-new condition for a significant cost savings over replacing them out-right.

“Headers can get extremely hot during a race," explains Steve. "That heat makes the tubing of the headers a lot easier to bend. If a race car is involved in a wreck, a knock all the way down at the merge collector can bend the tubing up near the exhaust flange." He should know: In the 14 years that PRO-FABrication has been building custom headers - for everyone from Sprint Cup teams to your average Saturday-night racer and everyone in between - he's seen and built it all.
 
Header tubes are selected for one reason: performance. Want to evacuate exhaust gases from the combustion chamber as cleanly and efficiently as possible? Use a round tube with as few bends as possible. If, for any reason, the tubing becomes kinked, warped, squashed or anything other than perfectly round, the interior surface area of the pipe is reduced, as is its ability to flow exhaust gases from the engine. Now you’re looking at the dreaded backpressure.

While small dings and even small flat spots aren’t a big deal, kinked or bent pipe IS a big deal and should be repaired.

Detecting header pipe that has been knocked out-of-round is more difficult than checking for cracks. The best way to do it is to wait until the headers have cooled and use your hand to feel each pipe. Don't always trust your eyes; they can deceive you. If you find damage, most problems are easily repaired if you can find a qualified header fabricator. Be careful when using your local muffler shop for repairs. Making the proper bends for header tubing requires a mandrel bender. A good one goes for around $100,000 and it is unlikely you are going to find one anywhere other than a specialized racing fabricator.

“Header repair is fairly straightforward and often preferable to going out and buying a new set,” Sousley says. “The headers I build are mostly for Sprint Cup and Nationwide Series teams. They are custom to the engine builder’s specifications and run about $3,000 for a set. Generally, we can repair a stainless-steel set of headers for $350 to $600 per side. Mild steel headers are even less: $200 to $300. So you can see there's a pretty significant savings, even over buying a prefab set straight out of a catalog. Merge collectors can be costly, so even if that's all you manage to salvage, you’re still coming out ahead.”

We have added .130 wall tubing as an option for tail pipe material. PRO-FABrication now offers four options of material thickness for COT tailpipes:  .049 410 Stainless, .065, .083, and .130 wall AKDQ. We also have eight options for tailpipe (Boom-tube) heights available- 1 ¼ -1 ½ -1 ¾- 2- 2 ¼- 2 ½- 2 ¾- 3". We are offering tailpipe construction to any degree of process, be-it custom-bent tubing and components, tack welded assemblies, or completely welded assemblies.

Teams can count on PRO-FABrication to provide complete custom exhaust systems with the exceptional craftsmanship we've come to be known for. This coupled with our superior customer service makes our header systems, and hence, your team, tough to beat.
