Banks Power Monster Exhaust for 04-06 Jeep Wrangler TJ with 4.0L

Constructed entirely of heavy-gauge stainless steel, Banks Monster features a supersized, 2.5-inch tailpipe with a stainless tailpipe tip polished to a mirror finish. Banks Monster muffler, its straight-through performance muffler, is the industry's least restrictive. In comparison tests, Banks muffler flowed 501.2 cfm at 1 psi—a 140% improvement over the stock exhaust's 208.6 cfm, and about 44% better than the nearest competitor.

Monster virtually eliminates backpressure from the catalytic converter back, for more power and efficiency; and an authoritative, yet civil, exhaust note. For maximum results, combine with Banks TorqueTube® system.
