Flowmasters new American Thunder axle-back system for the 2018 Jeep Wrangler JL is perfect for the person looking for maximum performance and ground clearance from their exhaust system. This 2.50 inch system features a 409S stainless steel mandrel bent tailpipe with a 3.00 inch polished stainless steel tip and fits both 2 and 4 door models with the 3.6L V6 engine. This system replaces the factory transverse muffler providing a moderate to aggressive sound level. This allows for better ground clearance when driving off-road. Because the tailpipe is tucked up so high, an aftermarket metal bumper is recommended. The exhaust system is manufactured in the USA. Designed for an easy fit, this system includes all necessary parts and hardware for installation.
