Gibson Aluminized Cat-Back System for 04-06 Jeep Wrangler TJ Unlimited with 4.0L I-6 Gasoline Engine

Excellent power-producing exhaust systems for the enthusiast who wants the most from his or her Jeep. These systems are engineered to give you maximum pulling power, and feature heavy-duty construction for off-road use. Features smooth, mandrel-bent, 14-gauge aluminized tubing for non-restrictive flow. The Superflow muffler's fully welded case has baffled chambers to produce more power and a mellow sound. The polished stainless exhaust tip will not rust. Installs easily behind the catalytic converter.
