Banks Power Monster Exhaust System | 2001-2004 Chevy/GMC Duramax LB7 6.6L EC/CCLB

Banks 4 inch Monster Exhaust for your 2001-2004 Chevy/GMC Duramax LB7 6.6L (extended cab/long bed or crew cab/long bed) is made of rugged, long-lasting 100% stainless steel. It fits better than the competition, because Monster Exhaust utilizes the factory hangers and maintains proper clearance to all under-vehicle components. All flow, show and go! With nearly five decades of engineering airflow improvements, Banks has mastered the art of maximizing flow while minimizing backpressure. The polished straight-through Monster Muffler, mandrel-bent head pipe assembly (non-cat-converter-equipped vehicles only), intermediate pipe(s) and tailpipe nearly triple the exhaust flow, cut backpressure up to 98%, lower exhaust gas temps and deliver more power to the ground. And the 5 inch polished rolled-edge tip has an adjustable clamp for positioning on tailpipe. Get it in your choice of chrome-over stainless or high temp black! Engineered to ditch the drone. Many straight-through mufflers deliver an obnoxious drone that overpowers conversations. Banks Monster Muffler is extensively sound-tested and engineered with a unique expansion chamber and high-temperature packing. Instead of a drone, you're treated to a rich exhaust note that's authoritative, yet civil. It sounds as great as it looks!
