4-inch stainless constant-diameter cat-back pipes and straight-thru muffler dramatically improve flow up to 122% and lower EGTs. Virtually eliminates backpressure, rich, throaty sound. Formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps.Banks replaces the factory's restrictive muffler with a polished-stainless Monster muffler featuring a straight-through 4-inch diameter path that flows up to 129% better than stock. The Banks-designed expansion chamber dissipates the annoying mid-range exhaust drone that accompanies most straight-through mufflers. Monster muffler utilizes spun ceramic, very-high-temperature packing, and delivers an authoritative--but never intrusive--exhaust sound. And the 5-inch polished rolled-edge tip has an adjustable clamp for positioning on the tailpipe. Get it in your choice of chrome-over stainless or high temp black! (And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish.)
