Banks Power Monster Exhaust System, Single Exit, Black Round Tip 48643-B

4 inch constant-diameter system;Flows up to 122% better than stock;Turbo Back System;5 inch BLACK tip

The 4 inch Monster exhaust turbo-back system flows up to 122% better than stock and virtually eliminates backpressure. The system's pipes bolt behind the turbocharger. Banks' streamlined 4 inch turbine outlet pipe, intermediate pipe(s) and tailpipe are 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 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.)
