Banks Power - Monster Exhaust (Chrome Tip) - 06-07 Chevy/GMC LLY, LBZ | Std cab, long bed | Cat converter

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. 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 plus, you get to pick whether you want a polished chrome or black tip! Double-walled design with 1/2" air gap keeps heat from tarnishing the exterior finish. Adjustable clamp for positioning on tailpipe.
