Jeep Wrangler JK Performance Exhaust - Rear - Flowmaster - American Thunder Cat-Back - `07-`18

Jeep Wrangler JK Performance Exhaust - Rear - Flowmaster - American Thunder Cat-Back - `07-`18. A high-clearance cat-back for 2007–2018 JK 2- and 4-door models with 3.8L or 3.6L engines, tuned for a moderate-to-aggressive sound.

This system replaces the factory transverse muffler and relocates the compact Super HP-2 behind the catalytic converter for a tighter, high-clearance path. A mandrel-bent 2.50-inch 409 stainless tailpipe feeds a 3.00-inch polished stainless tip tucked under the rear bumper. It reuses factory hanger locations, includes required parts and hardware, and carries Flowmaster’s Lifetime Limited Warranty. Because the tailpipe sits so high, an aftermarket metal rear bumper is recommended.
