Monster Exhaust System

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.
