Jeep Monster Exhaust 4.0L 6-cyl. and 2.5L 4-cyl., '91-05

Gale Banks Engineering

1991-05 4.0L and 2000-02 2.5L WRANGLER: 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 498.2 cfm at 1 psi—a 139% 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.
