Cat Back Exhaust Kit 00- 06 Jeep Wrangler TJ 4.0L

The Flowmaster Cat Back Exhaust Kit for 2000–2006 Jeep Wrangler TJ 4.0L is a stainless steel, single-exit exhaust system designed to replace the factory exhaust from the catalytic converter rearward. Built around a 2.5-inch diameter tubing with a 3.5-inch black ceramic-coated tip, this cat back exhaust for the Jeep TJ delivers improved exhaust flow compared to stock while maintaining a direct bolt-on fit to the factory mounting points.

The Flowmaster 717865 cat back kit is engineered specifically for the Jeep Wrangler TJ's inline-6 4.0L engine and two-door configuration. Constructed from stainless steel to resist corrosion in harsh off-road and outdoor environments, the system features mandrel-bent tubing that maintains consistent diameter through bends to reduce turbulence. The 3.5-inch black ceramic tip provides both durability and a finished appearance. At 19.02 lbs, the complete assembly is manageable for installation while maintaining structural integrity under continuous use.

This exhaust system suits Jeep TJ owners seeking a direct replacement for worn or restrictive factory exhaust. Whether running 2000, 2001, 2002, 2003, 2004, 2005, or 2006 model-year Wrangler TJ two-door models, the single-exit design simplifies installation compared to custom fabrication. The stainless construction and corrosion resistance make it practical for both street and trail use, where exposure to moisture, salt spray, or mud demands durability. Off-road enthusiasts and weekend explorers alike benefit from the bolt-on convenience and proven Flowmaster engineering.

Cat back exhaust kits represent the most straightforward exhaust upgrade for vehicles where the catalytic converter remains stock. By targeting only the rear section, this approach preserves emissions compliance while allowing owners to customize their exhaust tone and flow characteristics. The Flowmaster brand is recognized for its tuning expertise in the off-road and performance market, and this system reflects that focus through tested, ready-to-install components rather than experimental designs.
