Steeda's 3" diameter Cat-Back Exhaust System for the 2018+ Ford Mustang GT gives your S550 a deep, tough, and powerful sound. This system is designed to fit to your stock system and fits most long tube headers. Bring out the performance of your American-made muscle car with this deep exhaust. Our cat-back exhaust design provides maximum horsepower due to the oversized 3" tubing diameter, the best flow, and excellent sound without any annoying drone.

Quality construction. This Steeda S550 Cat-Back Exhaust System is constructed from 304-stainless steel for better than OE equivalent corrosion resistance. The quad tips of our Steeda 3" cat-back exhaust are constructed from polished 304-stainless steel for a timeless look.

Easy installation. Installing this Cat-Back Exhaust takes only 2-3 hours using common hand tools. It can be completed at home with ease and is the perfect way to upgrade your Mustang.

Better exhaust flow. If you demand more power and potential, this exhaust delivers. The 3" diameter flows adequately whether you have a few add-ons or a full-blown power adder! Our exhaust kit includes necked-down adaptors for a factory-style connection to OE converters. You can be confident that this exhaust will not restrict your Mustang and hold you back from making more power.

Note: Fits fastback coupe only, will not fit convertible models.
