Silence Your Competitors. Unlike the lower-quality exhausts on the market, the Kooks Catted X-Pipe is designed to deepen and intensify the natural purr of your Mustang, not crank it up to an annoying whine.

Includes Kooks GREEN Cat Converters. A jump in horsepower doesn’t mean you should see an increase in your emissions as well. With the EPA-certified Kooks GREEN high-performance catalytic converters, your emissions output will be lower, and you won’t have to sacrifice performance.

Built With Only the Best. 304 mandrel-bent steel is a premium material, and the Kooks X-Pipe utilizes it to ensure ultimate durability. You won’t see the wear and tear that would occur with other, lower-quality materials. The stainless steel finish is a classic touch that makes this pipe not only functional but attractive as well.
