American Thunder Axle Back Exhaust System

American Thunder Axle Back Exhaust System; Single Out Rear Exit; Incl. 2.5 in. Tubing/3 in. Angle Cut Tips; 409 Stainless Steel;

The Flowmaster(R) American Thunder(R) Axle-back exhaust system for the 2018-2024 Jeep Wrangler JL is perfect for the person looking for maximum performance and ground clearance. The 2.50-inch tailpipe features a mandrel bent 409 stainless steel tailpipe finished off with a 3.00-inch polished 304 stainless steel tip and fits both 2 and 4 door models with the 2.0L Turbo or the 3.6L engine. This system replaces the factory transverse muffler reducing weight, improves ground clearance, and provides a moderate sound level that is not offensive or will be considered loud by most people. Because this system tucks the tailpipe up high, an aftermarket metal bumper is generally recommended. The exhaust system is covered by our Lifetime Limited Warranty. Designed for a perfect fit, this system includes all necessary parts and hardware for easy and quick installation you can do at home in about 15 minutes.
