This bolt-on SOR (Single Out Rear) emissions-legal system features a 2.50 inch mandrel bent inlet pipe, a stainless steel Outlaw Series muffler and a 2.50 inch mandrel bent tailpipe. The system finishes with a 3.00 inch polished Flowmaster stainless steel tip. The system is designed for an easy fit and includes all necessary parts and hardware for installation.
