2005-2009 Roush Extreme Performance Cat-Back Exhaust

This Roush Extreme Performance Cat-Back System will fit the 2005 to 2009 GT and 2007 to 2009 Shelby GT500 Mustangs with the factory rear valance.

Let your engine howl with a Roush Extreme Performance Cat-Back System. This innovative Roush exhaust system features a muffler-delete design with resonators mounted directly after the Mid Pipe, that results in increased air flow, and a unique sound, with no in-cabin exhaust drone.

Constructed from CNC mandrel bent 2.50-inch diameter stainless steel tubing for a durable long life, the Extreme Performance Cat-Back System features two 304 polished stainless steel 4-inch tips with embossed "ROUSH" logo.
