      Loud and Aggressive Sound. The Flowmaster Outlaw Axle-Back Exhaust with Black Tips is specifically designed to release race-optimized, aggressive exhaust notes with a moderate interior tone. This particularly smooth sound is a product of Flowmaster’s technology, featuring an increased surface area and angle of the tapered exit that refocus the sound energy as the hot gases flow out of the muffler.

      Maximum Power and High Performance. Flowmaster innovatively uses its laminar flow technology to deliver a powerful performance. This Outlaw Axle-Back Exhaust is efficiently engineered with perforation patterns that maximize exhaust flow. Furthermore, the cool shell internal design uses a thermal barrier that minimizes exterior muffler temperature. This ingenious combination of structures ultimately provides the Jeep with an enhanced power, improved torque, and better fuel efficiency.

      Durable Construction. Flowmaster uses high-grade, 409 stainless steel, mandrel-bent tubing for its Outlaw Axle-Back Exhaust. This muffler assembly effectively withstands the corrosive attacks and high temperatures of the exhaust gases. It is also fortified with a black ceramic finish. Additionally, the pair of black ceramic coated exhaust tips are constructed from durable, 304 stainless steel, stylishly reinforcing the contemporary and fierce stance of the 2018-2020 JL Wrangler.

      Simple Installation. This Outlaw Axle-Back system is designed for a simple, bolt-on, no-weld installation that takes about 1 hour. It directly fits the JL’s factory hangers and can be installed with light-to-moderate mechanical skills.

      Application. This Flowmaster Outlaw Axle-Back Exhaust with Black Tips fits 2018-2020 3.6L Jeep Wrangler JL models.
