The Flowmaster American Thunder Cat-Back Exhaust System for the 2007-2018 Jeep Wrangler JK is a high-performance exhaust upgrade designed to enhance both sound and ground clearance. Constructed with mandrel-bent 2.50-inch stainless steel tubing and featuring a 3.00-inch polished stainless steel tip, this system replaces the factory transverse muffler and relocates the Super HP-2 muffler behind the catalytic converter. It delivers a moderate to aggressive exhaust note, improving sound quality and vehicle presence while maximizing off-road ground clearance. The system is built for durability and ease of installation, including all necessary hardware and parts, and is backed by a Lifetime Limited Warranty.
This exhaust system is compatible with both 2- and 4-door Jeep Wrangler JK models from 2007 to 2018, equipped with either a 3.8L or 3.6L engine. It is designed as a direct bolt-on replacement for the factory exhaust, providing performance gains and a more aggressive sound profile. Due to the high tuck-up of the tailpipe, an aftermarket metal bumper is recommended for optimal clearance. Ideal for off-road enthusiasts and daily drivers seeking improved exhaust flow and sound, this system offers a straightforward installation and long-lasting performance.
