2001-2005 GM 6.6L DURAMAX LB7/LLY
The polished-stainless Monster 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 exterior mirror finish. Adjustable clamp for positioning on tailpipe.
