    More Power. Combining the two exhaust streams from both sides of your V8 engine effectively enlarges your exhaust system. With the Kooks Off-Road H-Pipe, you get what you came here for—more power, more of that mythical quality known as torque, and, ultimately, better performance.

    More Pleasing Exhaust Sound. With a typical V8 engine, the exhaust pulses from each side travel through the exhaust system very close together. In some cars, this makes an annoying popping sound. Putting in an H-pipe lets the two pulses exit through both sides of the system, reducing exhaust noise by 2 as much as decibels.

    Cat-Free Environment. It's not that we don't love cats, we just don't like them in our exhaust systems. Removing them, as Kooks has from their Off-Road H-Pipe, improves exhaust flow and performance. That's why they are strictly off-road, because they are not street legal anywhere that emissions are a problem.

    Durable Stainless Steel Construction. Kooks chose aircraft-grade 304 stainless steel for its Off-Road H-Pipes because of its long-lasting resistance to corrosion and its durability. This extremely versatile grade of steel is one of the most widely used austenitic stainless steels (look it up, you'll learn more).

    Application. The Kooks Off-Road H-Pipe has been specifically fabricated to fit all models of 2007 to 2014 Mustang GT500 with long tube headers.
