2021 Cat Back Exhaust Kits

Cat-back exhaust kits are one of the most popular upgrades for 2021 Mustangs. Though the car sounds great from the factory, aftermarket cat-backs give you more volume and a better tone. They also make your exhaust pipes less restrictive, improving performance.

A cat-back exhaust kit typically includes new resonators, mid-pipes, mufflers, and exhaust tips. The resulting exhaust note will range from slightly louder than stock to a deafening roar. In general, less restrictive cat-backs are usually louder and provide bigger increases in power. If you want to maximize your exhaust system's power production, combine your new kit with a cold air intake and custom tune.

Our cat-back systems come from quality brands like Borla, Corsa, and Ford Performance to help you get the most out of your aftermarket exhaust setup!
