Banks Power 51313 Monster Exhaust System for 2000-2003 Jeep Wrangler (4.0L) - 2.5" Stainless with Chrome Tip

Fits select 2000-2003 Jeep Wrangler models including Rubicon, Sahara, Sport, X, and SE (4.0L).

The Banks Power 51313 Monster Exhaust System is engineered to replace the restrictive factory exhaust from the catalytic converter back. Featuring a heavy-duty 2-bolt flange for the catalytic converter connection, this system utilizes 2.5-inch mandrel-bent stainless steel tubing to maintain a constant diameter through every curve, significantly reducing backpressure and lowering exhaust gas temperatures. The straight-through Monster muffler provides an authoritative, civil exhaust note without the drone of lesser systems.

In rigorous flow testing, the Monster muffler outperformed stock units by 140%, flowing 501.2 cfm at 1 psi compared to the original equipment's 208.6 cfm. This dramatic improvement in airflow translates to better engine efficiency and power across the RPM range. The system is finished with a mirror-polished stainless steel tip for a professional, durable appearance.
