Classic Sound. Your Mustang has the perfect body, but how does it sound? If you're still using the stock exhaust on your 2015-2017 GT, the sound is, shall we say... lacking. Upgrade with Kooks' Full 3" Cat-Back Exhaust with H-pipe to get the perfect rumbly roar you desire. This system requires a set of Kooks Long Tube Headers, which will only further improve the sound and performance of your 5.0L Mustang.

Durable Construction. Constructed from aircraft quality T304 stainless steel for its corrosion resistance and durability, this full 3" Kooks Cat-Back System with H-pipe features mandrel-bent tubing, providing a smooth and even pathway for exhaust gases. This convertible exhaust system is completed with two 3” oval race mufflers and two 4” double wall, slash-cut polished tips for an eye-catching finish.

H-Pipe for Muscle Car Growl. Kooks utilizes an H-Pipe to balance out the exiting exhaust gases and to preserve the back pressure necessary to maintain low end torque. The included H-Pipe not only helps with horsepower and performance, but it also adds a classic muscle car rumble to the sound of your 5.0L with its simple crossover pipe design.

Direct Fit Upgrade. The Kooks Cat-Back Exhaust with H-Pipe includes all the hangers and clamps necessary to bolt straight up to Kooks Long Tube Headers. No modifications or cutting is required, making this Cat-Back a direct fit bolt-on upgrade.

Application. The Kooks 3" Cat-Back Exhaust with H-Pipe and Polished Tips is specifically designed for 2015-2017 GT 5.0L Mustangs equipped with a pair of Kooks Long Tube Headers. Please select your Mustang's trim option - convertible or fastback - when adding to cart.

Technical Note. Not legal for use on pollution controlled motor vehicles; intended for off road use only.
