3 inch stainless mandrel-bent cat-back pipes and straight-thru muffler cut backpressure up to 93%. Improve flow up to 104%; 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 2-1/4 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% better than the stock factory exhaust while reducing backpressure by 93%. This allows the Nissan Frontier to produce more power with less work, and cuts 0-60 MPH times by 4-tenths of a second. Monster exhaust features an ultra-low restriction, 3 inch, straight-through, heavy-gauge polished stainless Monster muffler that outflows the stock muffler by 183% 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 Polished-stainless 4 inch rolled-edge, air-cooled tailpipe tip.
