All our pipes come in aluminized steel and stainless steel, materials used by all the major exhaust system manufacturers to ensure durability and great appearance. Don’t put a lot of time and effort into an exhaust system project using ordinary steel tubing only to see it rust away. Painting such tubing, even with so-called high heat paint, isn’t the answer. It’s difficult to get complete coverage, you’ll have to recoat repeatedly and still may get rust.

We have the large diameter pipes you want and all pipes are mandrel bent. Mandrel bending ensures smooth bends and makes sure the pipe maintains its size and shape throughout the entire length. Tubes that aren’t mandrel bent can lose a percentage of their diameter in sharp bends, which creates exhaust flow restriction. Mandrel bending provides consistent bends so exhaust flow is uniform throughout the entire length of the pipe, and so each pipe flows as much as possible, and more exhaust flow equals better performance.

The addition of an H-pipe or an X-pipe to a dual exhaust system has been proven to unleash more horsepower. With these pipes, exhaust flow is increased because now both cylinder banks can make use of both sides of the exhaust system, and increased exhaust flow means more power. Many of these pipes come with factory style flanges to enable easy connection to components like catalytic converters, and some are designed to facilitate the exhaust system connection to long tube headers. We also offer X-pipes for off-road use only that eliminate the catalytic converters in the system.

We carry Flowmaster Scavenger series header collectors and Y-collectors. Both use the principle of pulse technology. Each tube and the way it merges in the collector are specially designed to take advantage of the engine’s exhaust pulses. As the exhaust pulse travels down the tube, its momentum creates a vacuum behind the pulse as the exhaust valve closes. This helps “scavenge” the remaining exhaust from the combustion chamber. The large D-shaped ports provide a larger surface area for the exhaust pulses to pull each other along as they travel the length of the collector.

    You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.
