Steeda is proud to introduce our new 3" diameter Cat-Back Exhaust System for the 2018-2023  Ford Mustang Fastback GT & Bullitt. We have designed this system to bring out the performance in your American made muscle car. Our cat-back exhaust design provides maximum horsepower due to the oversized 3" and the best flow and sound without annoying drone. NOTE this system is NOT an active valve system, so for someone who wants all V8 soundtrack all the time without the weight and complexity of the valves system this is for you.  You should also purchase the AWE "Valve Bracket" to keep your valves safe and plugged in.

This system will also fit on US Import non active exhaust 2024+ GT Mustangs
