Product Details

Looking to increase your total horsepower, torque, and significantly beef up your sound? American Racing Headers is a group dedicated to providing the best all around headers money can buy! 100% Made in the USA of high quality 304 stainless steel and using 3/8" thick laser cut flanges for a warp free seal, you can trust that your exhaust components will be built to the highest specifications and will more than likely outlast the rest of your car.

To ensure high power output and the best sound possible, the 304 stainless steel tubing is routed in a specific way to optimize flow. Using a patented rotational firing, 6-into-1 long tube header system for the S54 engine, exhaust gases are directed in way that makes them flow highly efficiently and prevents any sort of restriction that would otherwise limit your engine's total output. The gas exits the engine's head then flows down the system, in time, to the 6 to 1 Merge Collector. This Merge Collector directs the gases by taking advantage of the natural firing exhaust pulses to create a spinning vortex effect that scavenges the exhaust from the primaries and keeps the exhaust gases moving at their optimum speed. This means more flow and more power at every point of the throttle band all the way up past redline.

This header system comes with a 200 cell metallic substrate catalytic converter for extreme durability and to prevent check engine lights in the long run.
