Fits 2005-2009 Ford Mustang GT and 2007-2009 Shelby GT500.

The Roush Enhanced Sound Dual Cat-Back Exhaust Kit (MPN 403936) provides an aggressive external rumble without the interior cabin drone typically found in high-performance systems. This high-flow exhaust is engineered to reduce backpressure, supporting gains in horsepower and torque by allowing the engine to breathe more efficiently than with stock components.

  • Precision Construction: 2.5-inch diameter stainless steel tubing is shaped with CNC mandrel benders to maintain a consistent internal diameter, ensuring maximum exhaust velocity through the bends.
  • Premium Finish: The system features dual 4-inch tips crafted from polished 304 stainless steel and finished with an embossed ROUSH logo.
  • OEM Integration: This kit is designed to fit 2005-2009 Mustang models equipped with the factory rear fascia, utilizing existing mounting points for a secure installation.

The kit includes 2.5-inch mandrel-bent piping, 4-inch polished tips, and all hardware necessary for a direct-replacement installation.
