This Ford Mustang exhaust kit is crafted using a CNC bender, ensuring smooth mandrel bends and a consistent inside diameter throughout the bended area. This results in a significant boost in flow compared to stock/serrated-bent pipes. The kit is constructed with premium 2.5-inch diameter stainless steel tubing and features 4-inch diameter tips made from polished 304 stainless steel, emblazoned with the "Roush" logo. Included with the system are OEM stainless steel exhaust clamps, which provide a secure, leak-proof seal without damaging the pipes during tightening.

The Roush Resonator Off-Road Exhaust Kit fits 2005 - 2009 Mustang GTs and GT500s with factory rear fascia.
