Banks Power Monster Exhaust System for 2004-2006 Jeep Wrangler (4.0L) - 2.5" Stainless Steel with Cerakote Black Tip

Fits 2004-2006 Jeep Wrangler models including Rubicon, Sahara, SE, Sport, Unlimited, and X (4.0L).

Replace your restrictive factory exhaust with the Banks Power Monster Exhaust System to significantly improve engine breathing and efficiency. Engineered specifically for the 4.0L Jeep Wrangler, this system features 2.5-inch mandrel-bent stainless steel tubing that eliminates the sharp bends found in factory pipes. The included straight-through Monster muffler is designed to virtually eliminate backpressure, allowing your engine to exhale more freely for increased power and improved throttle response.

In performance testing, the Banks Monster muffler flowed 501.2 cfm at 1 psi—a 140% improvement over the stock exhaust's 208.6 cfm. This dramatic increase in airflow helps lower exhaust gas temperatures (EGTs) while providing an authoritative, civil exhaust note without annoying drone. The system is finished with a heavy-gauge Cerakote black stainless steel tip for a durable, high-performance look.
