Banks Power Monster Exhaust System for 1997-1999 Jeep Wrangler (4.0L) - Stainless Steel with Cerakote Black Tip - 51312-B

Fits 1997-1999 Jeep Wrangler Sahara, SE, and Sport models (4.0L).

The Banks Power Monster Exhaust System (51312-B) replaces your restrictive factory exhaust with a high-flow, 2.5-inch mandrel-bent stainless steel configuration. Designed to virtually eliminate backpressure, this system features a straight-through Monster muffler that flows up to 501.2 cfm at 1 psi—a 140% improvement over the 208.6 cfm stock flow rate. This increased capacity improves efficiency and provides an authoritative, civil exhaust note while lowering exhaust gas temperatures.

Built for durability on and off the trail, the system is constructed from heavy-gauge stainless steel and uses a slip-fit connection at the catalytic converter outlet. The system is finished with a 2.5-inch stainless steel tailpipe and a premium Cerakote Black tip.
