Banks Power Monster Exhaust System | 2006-2007 Chevy 6.6L, ECSB Extended Cab Short Bed

4 inch stainless constant-diameter pipes and straight-thru muffler for your 2006-2007 Chevy/GMC Duramax 6.6L (extended cab/short bed) improve flow up to 176% and lower EGTs, cuts backpressure up to 98%, rich authoritative sound. Banks' 4 inch 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 inch 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 inch 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 inch air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
