The MRT Interceptor Axle Back Exhaust for the 2005-2010 Mustang GT and 2007-2010 Shelby GT500 offers tough, muscle-car sound that turns heads for the right reasons. The free-flowing MRT Interceptor muffler provides a deep, muscular exhaust note. The MRT team of engineers went to work and the elusive system has finally arrived: Meet the Interceptor series of Axle Back Exhausts. At start up, Interceptor exhausts provide a deep, performance exhaust note. Passer-bys will hear a tough and tasteful tone that commands respect without screaming at its audience. There's no need to worry about being heard when it counts, the free-flowing Interceptor Muffler opens up in the higher RPM range to attract the attention you crave when you're getting on it. MRT Performance manufactures our Interceptor Axle Back Exhaust from the highest grade 304 Stainless Steel. This premium material is light-weight, supremely durable against rust and corrosion resistant. Installation of the exhaust is simple and drill-free. The MRT Interceptor Axle Back clamps-on directly in place of the factory axle back. 3.5-inch polished Stainless Steel exhaust tips come pre-welded to the axle back and are included with purchase. The Stainless tips can also be finished in Matte Black using Cerakote for an additional $80.00. Cerakote is a high temperature, durable ceramic coating. Cerakote offers a sinister look for your Mustang that can withstand the rigors of high-performance driving.
