Every Kooks H-Pipe is designed to satisfy the exact needs of your engine, so you can rest assured that it will be the perfect fit for your Mustang GT, delivering that perfect race car growl you've been searching for.

    Application. The Kooks Catted H-Pipe is designed for use with any 2011 to 2014 Ford Mustang GT with a 5.0L Coyote engine. Kooks Long Tube Heads are required.
