Roush 2011-2014 Ford Mustang GT & Shelby GT500 Dual Axle-Back Exhaust with Round Tips (421127)
$799.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2011-2014 Ford Mustang GT and 2011-2012 Shelby GT500 models.
The ROUSH Axle-Back Exhaust Kit (MPN 421127) is engineered to provide an aggressive, signature V8 exhaust note while improving airflow over the stock system. This dual exhaust kit features an innovative open-chambered muffler design that provides a deep, performance-oriented sound profile without the intrusive in-cockpit drone or "boom" often associated with aftermarket exhausts at cruising speeds.
Constructed for durability, the mufflers and inlet pipes are manufactured from 409 stainless steel. The system is finished with dual 304 stainless steel round tips featuring a chrome flashing process for a brilliant mirror finish. Each tip is embossed with the ROUSH logo for an authentic aesthetic. This kit is a direct bolt-on upgrade that utilizes the vehicle's factory mounting points and includes all necessary hardware for a straightforward installation.
