This Roush Axle-Back exhaust system features a hollow chamber muffler that not only increases flow, but provides that aggressive muscle car sound that you've been looking for! The unique design of the muffler offers a great exhaust note without the in-car 'drone' found with many performance exhausts.
This exhaust system utilizes 409 stainless steel throughout the piping and unique chambered mufflers for a durable, long lasting life. This system is finished with 304 stainless steel tips with a new chrome flashing process to resist discoloration from exhaust heat.
This Roush Performance Axle-Back exhaust system is specifically designed to fit the 2011-2014 GT & 2011-2012 GT500 Mustang with the factory GT rear valance, or aftermarket Roush rear valance.
