4 inch stainless constant-diameter pipes and straight-thru muffler improve flow up to 176 percent and lower EGTs, cuts backpressure up to 98 percent, rich authoritative sound. Banks 4 inch heavy-duty stainless Monster exhaust system cuts backpressure up to 98 percent and flows up to 176 percent better than stock. The streamlined intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps. The polished-stainless constant-diameter muffler features a straight-through 4 inch diameter flow path with an exclusive expansion chamber to dissipate the annoying mid-range exhaust drone. Monster muffler utilizes spun ceramic, very-high-temperature packing, more than triples stock flow, and delivers an authoritative exhaust sound. Huge 5 inch polished-stainless steel tailpipe tip sports a rolled edge – plus, you get to pick whether you want a polished chrome-over stainless or high-temp Black tip! And to help keep it looking good, there’s a 1/2 inch air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
