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.. The Banks Monster Exhaust is engineered using computational fluid dynamics (CFD) software then tested on both dyno and on-road. Reducing backpressure allows the engine to expel spent gasses with less effort. Less pumping loss means more horsepower, lower EGTs, and improved fuel economy. The Monster Exhaust system cools while flowing up to 80% better than stock! Cooling without killing flow is a major challenge. But the Monster Exhaust wins on both counts thanks to its mandrel-bent constant-diameter tubing and huge Ob-Round patented SideKick tip. The tip is the key. Its unique shape mixes hot exhaust gas with cool ambient air. And, it keeps your trailer safe by directing exhaust gasses to the side.
