Get the performance boost you crave for your GT Mustang while staying EPA friendly with a Kooks Green Catted X-Pipe. Designed for use with Kooks Long Tube Headers, this X-pipe features two Kooks Ultra High Performance Green Catalyst Converters for less restriction. Without robbing horsepower, the EPA-compliant system works on applications up to 800hp and handles exhaust temperatures as high as 1500F.

The Kooks X-Pipe not only increases the power of your Mustang, but it also changes its sound as well. The modern X crossover design of this Kooks Mid Pipe will add a loud raspy, race car style growl to the sound of your exhaust. While being louder than stock, the sound is not overbearing or obnoxious.

Able to handle exhaust temperatures of up to 1500F, these GreenCats work exceptionally well on both force inducted and naturally aspirated Mustangs.
