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 muscle-car sound. By deleting your mufflers, the KR Axle-Back Exhaust lets the beast inside your engine be heard. Your Mustang will sound louder, giving off an attention-getting roar. The MRT KR Muffler-Delete Axle-Back Exhaust is manufactured out of the highest quality 304-grade stainless steel, making it durable and light-weight. The stainless steel can be polished to get that show car shine. 3.5" polished stainless steel exhaust tips come welded to the axle-back and are included with the purchase of the exhaust system. The KR Muffler-Delete Axle-Back features easy, direct bolt-in installation. The MRT Axle-Back clamps-on directly in place of the factory axle-back. No drilling or welding is required. The KR Muffler-Delete Axle-Back (91A150) fits the 2005-2010 Mustang: V6, GT and GT500 models.
