These Mustang axle-back exhaust systems provide your S197 or S550 with better looks, increased horsepower, and more performance. S197 Axle-Back kits bolt up directly to your factory exhaust system and feature new wider piping, mufflers, and exhaust tips. S550 axle-back exhaust kits require a cut and clamp approach as the factory exhaust is welded together. This is usually one of the first modifications done to this body style Mustang as it looks great and gives you that true American muscle car sound. LMR.com carries a full line of axle backs made by leading manufacturers in the industry such as SVE, Flowmaster, Ford Racing, SLP, Pypes, Roush, Borla and MBRP. Pair it up with a new mid-pipe and a set of headers for the perfect exhaust system! Get yours today and get your Mustang sounding, performing, and looking better than the competition!
