Monster® Exhaust, 4.0L
Constructed entirely of heavy-gauge stainless steel, Banks Monster features a supersized, 2.5-inch tailpipe with a blac tip. 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.
