JBA 04-06 Jeep Wrangler LJ 2.4L/4.0L 304SS Single Rear Exit Cat-Back Exhaust

If you're looking to get more out of your 2004-2006 Jeep Wrangler LJ, this JBA cat-back exhaust system is a solid choice. It's designed to replace your factory system with a freer-flowing setup that can help your 2.4L or 4.0L engine breathe a little easier. This means you can expect a noticeable improvement in both sound and performance.

JBA builds this system using 304 stainless steel tubing, which is known for its strength and resistance to corrosion, especially important for a part that's exposed to the elements underneath your Jeep. The tubing is mandrel-bent to maintain a consistent diameter throughout, ensuring smooth exhaust flow. It includes a high-flow stainless steel muffler that's tuned to give your Wrangler a more aggressive exhaust note without being overly loud inside the cabin. The system finishes with a polished chrome tip for a clean look out the back.

This cat-back system comes with all the necessary hardware for installation, including factory-style hangers to make mounting straightforward. It's designed as a direct replacement for your stock exhaust, so you won't need to do any cutting or welding to get it fitted. Just remember to check the manufacturer's instructions for the most accurate installation details.
