An axle-back exhaust system replaces the factory rear muffler and exhaust sections located behind the rear axle, following the OEM exhaust path for a clean, factory-integrated appearance and installation. Most applications are completed in under an hour using existing factory hangers and hardware, with no cutting or welding required on most fitments. With decades of exhaust engineering heritage spanning professional motorsport and street performance, the Borla ATAK Axle-Back is the definitive bolt-on upgrade for drivers who want to be heard.
