Chevy/GMC - 6.6L Duramax LLY-LBZ
Cool Sound. Cool Tip.
4" stainless constant-diameter pipes and straight-thru muffler improve flow up to 176% and lower EGTs; cuts backpressure up to 98%; rich, authoritative sound.
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. Double-walled design with 1/2" air gap keeps heat from tarnishing the exterior mirror finish. Adjustable clamp for positioning on tailpipe.
