The new Flowmaster American Thunder cat-back exhaust system for the 2007-2018 Jeep Wrangler JK is perfect for the person looking for maximum performance and off-road ground clearance.

The system features a mandrel-bent 2.50-inch stainless steel tailpipe with a 3.00-inch polished stainless steel tip tucked up high under the rear bumper for maximum clearance.

Because the tailpipe is tucked up so high, an aftermarket metal bumper is recommended.
