How Does it Work?

GP Headers supplies the builder with a set of aluminum adjustable fabrication elbows. These unique infinitely adjustable elbows are compact enough to configure the most complex custom header designs right at your location. With a locking bolt at the pivot point of the elbow, the builder can simulate virtually any bend radius. Between the supplied elbows and the locally acquired PVC straight tubing, the builder can supply GP Headers with unlimited custom header design variations without bringing the car to their location.

From there the custom header mock up configuration is sent to GP. The custom header mockup design is then replicated in their multi mount welding fixture. This multi mount welding fixture is a system Stainless Headers Mfg. developed years ago to rapidly accommodate any custom header design. This allows GP Headers to fabricate and weld a set of custom headers that fits your very application perfectly.

After a precise fixture is made from your supplied mock-up, one of GP's skilled craftsmen fabricates your set of custom headers to your very specifications.

These infinitely adjustable elbows are the key to our header mock-up system. They incorporate a replaceable aluminum sleeve that the builder drills through the PVC into the sleeve. This fixes the PVC tubing in place for shipment into our facility.


The mock-up kit comes complete with all of the required components including appropriate numbers of adjustable elbows and instructions.


What makes their headers simply your best choice for custom headers?

Truly custom

GP Headers headers are made to fit your very application. The true meaning of custom.

Using only the finest true merge collectors in every design

Everyone of their headers incorporates handmade merge collectors. Sized for your very application, they can be configured with a three bolt flange, “V” band flange, turbo flange, straight tubing or what ever fits your application. Since GP makes them in-house, they can configure the header to fit your application without any compromises.

Constructed from the materials that’s just right for your application

We stock mild steel, 304 stainless steel and 321 stainless steel. Other high tech materials are also available for special applications, such as inconel and titanium. Just ask.

Purge tig welded

Often not done on most headers, purge welding is an essential part of good header construction. By filling the tubing with argon during the welding process, the internal tubing welds are shielded from oxygen. This gives an uncontaminated smooth weld internally. From years of welding aerospace components, we have developed techniques that make this cost effective in the automotive industry. For more information on purge welding see our “Precision Tig Welding Page”

Heavy flanges that match your actual port size

We use our heavy 3/8” thick CNC water jet cut flanges. We offer flanges matched to your very port size at no extra charge. During the header mock-up process at your location, we can supply you with the very flanges that we will use to build your headers with. These flanges can be matched to your port size by you and set back with the header mock-up for final fabrication by us.
