The Sound of Victory from Your Mustang. This Kooks axle-back exhaust system awakens the growl of V8 fury. It's designed to work perfectly with the Kooks Long-Tube Headers and Catted X-Pipe on your 2015-2018 Mustang GT350. This system decreases backpressure and increases performance, all while sounding great.

Integrates Perfectly. Kooks has designed this system to work perfectly with your Kooks-equipped Mustang. Each axle-back unit uses Ford's supplied exhaust actuator and retains use of the valence-mounted exhaust ports. 16-gauge stainless construction means it's built to last. Makes a perfect set with other Kooks performance exhaust components.

49-State EPA Legal. This Kooks exhaust kit is 49-state EPA legal, but is not for use in California on emissions-controlled vehicles. This kit is not CARB-compliant. Will not work with factory exhaust system.

Application. This Kooks axle-back exhaust kit fits the 2015-2018 Ford Mustang GT350. Requires use of Kooks Long-Tube Headers and 3" Catted X-Tube.

Q & A

Ask a Question

If I were to get a gt350 rear valance and put it on my GT could I use this on the GT? I want the corsa Double helix but the duel exhaust tips that come with the extreme cat-back won't line up with the gt350 rear valance which I find to be a far better looking quad tip setup than the roush rear valance. I wan't my car to be one of a kind and the sound to be too

    Unleash the beast!

    Perfect for the GT350. Its a big upgrade from the factory exhaust. It has the perfect sound that will really make your 350 stand out.
