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?or choose the new black tip! Monster Muffler, Banks' straight-through performance muffler, is the industry's least restrictive, more than doubling the stock flow.

Monster virtually eliminates backpressure from the catalytic converter back, for more power and efficiency?and an authoritative, yet civil, exhaust note.

Available for 2-door and 4-door models.
