The MRT Camaro SS: GFX Axle-back system has a loud, deep muscle car sound and is handcrafted in corrosion-resistant T304 Stainless Steel. This system includes 2.5" mandrel-bent tube with flared T304 Stainless Steel ends to fit the Camaro GFX factory package. This system is engineered for the best sound to match the Camaro vehicle and provides increased performance from the increased exhaust flow. The MRT Version 1 Camaro axle-back is louder than the Version 2 exhaust system with a similar performance note AND a sound that has more rasp and resonance or "drone".

For full Cat-Back performance and a rich deep tone, combine this MRT Axle-Back with the MRT h-pipe designed for the 10-15 Camaro SS MRT After Cat H-Pipe #92A801.

Application: 2010 thru 2015 Camaro SS, ZL1, 1LE, GFX Coupe & Convertible, 6.2L V8 engine.
Doesn't Fit: 2010-15 Camaro SS non GFX, use MRT Part #91A175 for this vehicle.
