Heavy-Duty, Customizable Axle-Back Mustang GT Exhaust Kit by ROUSH

The 2015-2017 S550 Mustang GT's factory exhaust system is an improvement over the earlier S550s, but even the optional active exhaust still leaves plenty of room for improvement, and you can never go wrong with ROUSH. This high-quality 304 stainless steel axle back exhaust system is a high-quality, versatile solution to your stock kit that enhances your pony's sound to your exact specifications.

Mandrel-Bent 304 Stainless Steel Tubing

ROUSH builds this axle-back exhaust system from the highest quality 304 stainless steel, which is mandrel-bent to provide optimal bends and maximum flow. Complete with quad 4" chrome flashed tips, this heavy-duty exhaust kit by ROUSH looks as aggressive as it sounds. ROUSH rigorously tests their exhaust kits for quality, ensuring they effectively reduce backpressure, improve flow, and add that classic ROUSH sound to any Mustang GT.
