3 inch stainless mandrel-bent cat-back pipes and straight-thru muffler cut backpressure up to 93 percent; improve flow up to 104 percent; throaty sound; 4-inch polished tip. Bolt-on direct fit. Frontier Pickup: A 3-inch mandrel-bent direct-fit cat-back system, Banks Monster exhaust improves mightily on the crimped 2.25-inch stock exhaust with an all-stainless steel system that uses larger diameter pipes for optimum exhaust flow. It's engineered to use the stock hangers, ground straps, and rear balancer, and includes a 3-inch constant-diameter Y-pipe-that replaces the restrictive factory Y-pipe. As a result, Monster flows 104 percent better than the stock factory exhaust while reducing backpressure by 93 percent. This allows the Nissan Frontier to produce more power with less work and cuts 0-60 MPH times by 4-tenths of a second. The Monster exhaust features an ultra-low restriction, 3 inches, straight-through, a heavy-gauge polished stainless Monster muffler that outflows the stock muffler by 183 percent while providing the unmistakable Banks Power sound. The finishing touch: a mirror-bright 4-inch polished Chrome over stainless tailpipe tip with a rolled edge - or get it in high temp black! (Click to see the Black tip version.) Vehicle-specific for easy bolt-on installation. Includes Stainless, 3-inch straight-through polished-stainless Monster muffler; Stainless, 3-inch constant-diameter Monster Y-pipe, and tailpipe; Polished-stainless, 4-inch rolled-edge, air-cooled tailpipe tip.
