*Some early model 2000 Wranglers had a round cat outlet pipe which will require the 1997-99 Jeep kit pn# 51312. This kit is designed for 2000-03 Wrangler with a flange on the back of the catalytic converter (not round slip fit pipe).
Monster® Exhaust, 2.5L / 4.0L
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.
Includes: Stainless Monster muffler; Stainless 2.5" tailpipe; Stainless tailpipe tip in polished chrome or black; Mounting hardware.
Photos 2-5 show the exhaust (with black tip) on a white Jeep JK 3.6L, but the photos will still give you an idea of what a Banks tip would look like on your 4.0L.
