Gale Banks Engineering 48634 Monster® Single Exhaust System for 02-05 GM Truck 6.6L LB7 and LLY Duramax Extended/Crew Cab Long Bed with Cat
Banks 4" heavy-duty stainless Monster exhaust pipes are constant-diameter to maximize flow and lower exhaust temperatures. The polished-stainless straight-through muffler delivers an authoritative, yet civil, exhaust sound. The system cuts backpressure up to 98% and flows up to 176% better than stock. The handsome 5" polished-stainless tailpipe tip with a rolled edge stays mirror bright.
Banks 4" Monster exhaust outflows stock and the competition. The streamlined intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to slash backpressure. Banks' 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. The 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.
