This Flowmaster® Outlaw Cat-back exhaust system is designed for all 2018-2024 Jeep Wrangler JL 2 & 4-door models with the 3.6L engine and is perfect for the person looking for an aggressive exterior and interior exhaust tone, along with the performance benefits of a free-flowing exhaust system. This bolt-on emissions-legal system features 2.50-inch mandrel-bent stainless steel tubing, a specially tuned resonator to reduce interior resonance, along with an optional non-resonated pipe if you want an even more of an aggressive sound. Other features include a race-proven Outlaw® Series muffler with dual 2.5-inch mandrel-bent tailpipes finished off with a large pair of 4.00-inch black ceramic coated stainless steel tips for an aggressive modern look. The system is designed for an easy fit using the factory hanger locations and includes all necessary parts and hardware for installation.
