Quickly, Conveniently Switch Between Open and Closed Modes

The 2018-2019 S550 Mustang GT's factory exhaust system is an improvement over the earlier S550s, but there is still plenty of room for improvement, and you can never go wrong with ROUSH. Their Active iO series axle-back kit allows you to choose between a loud, aggressive growl (open mode) and a subdued, smooth tone (closed) with the flick of the provided switch. The provided dual high-flow mufflers provide optimal flow and a great sound no matter what position you choose.

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 304 stainless steel polished 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.

Fitment: 2018-2019 Mustang GT 5.0L V8
