    Straight Forward Installation. The Outlaw Cat-Back Exhaust is designed for an easy fit to the specific application. Additionally, it comes with the necessary parts for either a split side or dual rear configuration. Flowmaster recommends welding the slip-fit connections for a more secure installation.
