Banks Power 17+ GM Duramax L5P 2500/3500 Monster Exhaust System - SS Single Exhaust w/ Black Tip

Stainless constant-diameter pipes and straight-thru muffler nearly doubles flow. Lower exhaust temps. Virtually no backpressure. Rich, throaty sound. Monster exhaust system flows better than stock and virtually eliminates backpressure. The streamlined intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow and lower exhaust gas temps. Banks replaces the factorys restrictive muffler with a polished-stainless steel Monster muffler, featuring a straight-through flow-path with a Banks-designed expansion chamber which dissipates the annoying mid-range exhaust drone thats so prominent in competitors straight-through mufflers. The muffler utilizes spun ceramic, very-high-temperature packing, more than doubles the stock flow and delivers an authoritative - but never intrusive - exhaust sound. A stainless steel tailpipe tip in your choice of polished chrome-over stainless or high-temp black sports a rolled edge. And to help keep it looking good, theres a 1/2 in. air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
