MRT is pleased to introduce the MRT KR Muffler Delete Axle Back Exhaust System for 2005-2010 Mustangs. The MRT KR Axle back delivers performance exhaust with intense, aggressive muscle-car sound. By replacing your factory mufflers, the KR Axle Back Exhaust lets the beast inside your engine be heard. Your Mustang will sound louder, giving off an aggressive attention-getting roar. The MRT KR Axle Back Exhaust is manufactured out of the highest grade 304 stainless steel, making it durable and light-weight. 3.5" polished stainless steel exhaust tips come welded to the axle-back and are included with the purchase of the exhaust system. 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. The KR Muffler Delete Axle Back features easy, direct bolt on installation. The MRT Axle Back clamps on directly in place of the factory axle back. No drilling or welding is required.
