Vehicle Fitment: 2006-2007 Chevy & GMC 6.6L LLY & LBZ Duramax Diesel, W/ Catalytic Converter | Fits Standard Cab/Long Bed

Note: This is a Side Exit, Stainless Steel Single Exhaust System W/ Black Tip

Banks 4" heavy-duty stainless Monster exhaust system cuts backpressure up to 98% and flows up to 176% better than stock. The streamlined intermediate pipes 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, theres a 1/2" air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right.
