The Flowmaster American Thunder Axle-back exhaust system for the 2007-2018 Jeep Wrangler JK is perfect for the enthusiast looking for maximum performance and ground clearance. The 2.50-inch tailpipe features a mandrel bent 409 stainless steel design for performance and corrosion resistance. The tailpipe is finished off with a 3.00-inch polished 304 stainless steel tip and fits both 2 and 4 door models with the 3.6L or 3.8L engine. This system replaces the factory transverse muffler reducing weight, improves ground clearance, and provides a moderate sound level. 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.
Features:
- Max Dyno Gains of 5 HP and 7 Lb.Ft. Torque
- Provides Maximum Clearance for Off-Roading
- Mandrel Bent Pipe Increases Exhaust Flow and Performance
- Stainless Steel Construction Offers Great Corrosion Resistance
- Utilizes the Factory Mounting Points for an Easy Installation
- Moderate Sound Level
- Backed by Flowmaster’s Lifetime Limited Warranty
