Monster® Exhaust

Banks' 4" heavy-duty stainless Monster exhaust system cuts backpressure up to 98% and flows up to 176% 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"-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" 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" air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.

This system has a "side single" exit

THE ULTIMATE DURAMAX PRODUCT SHOWCASE!

click for storyDoes this sound familiar? "KROQ (106.7 FM) is the most powerful rock station in the world. It is also the number-one-rated radio station in Los Angeles. Radio programmers nationwide have endlessly copied KROQ's formats." Sounds a lot like Banks Power ... powerful, often copied ... so what better partnership could there be than KROQ and Banks Power teaming up to create the insane "Roq Rig." It's got just about everything we make for the Duramax, so if you've got one and you're looking to take it to the next level (of power and awesomeness) take a sec and check out what all went into making this dream truck a reality...
