Monster® Exhaust, 3.8L
3.8L V-6: 2007-08 WRANGLER JK UNLIMITED 4-DR.
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. 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. For maximum results, combine with Banks TorqueTubes® Exhaust Manifolds.
Includes: Stainless Monster muffler; Stainless 2.5" tailpipe; Polished stainless tailpipe tip; Mounting hardware.
