High-Performance, Highly-Aggressive Sounding Axle-Back Exhaust System by ROUSH

The 2005-2010 Mustang GT or 2007-2010 GT500's factory exhaust system just doesn't do your aggressive muscle car justice, but thankfully we always have ROUSH to save the day. Their high-quality "Extreme" 409 stainless steel axle back exhaust system gets you that vicious muscle-car roar thanks to its straight-through resonator, plus with 2.5" mandrel-bent tubing, you'll optimize exhaust outflow and reduce backpressure as well.

Mandrel-Bent 409 Stainless Steel Tubing

ROUSH builds this axle-back exhaust system from corrosion resistant 409 stainless steel, which is mandrel-bent to provide optimal bends and maximum flow. Complete with dual 4" flash-chromed dual wall 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.
