Banks Power Single Monster Exhaust System for 2002-2005 6.6L GM Duramax LB7, LLY (Diesel) Extended & Crew Cab Short Bed With Catalytic Converter

The Banks Power Single Monster Exhaust System - 48633 is the open, free flowing, great sounding exhaust system for your 2002-2005 6.6L GM Duramax LB7 or LLY pickup with a extended or crew cab short bed configuration and equiped with a catalytic converter.

Physical fitment.
Why consider a cheap, ill-fitting aluminized exhaust? Banks 4" Monster Exhaust 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" polished rolled-edge tip has a double-walled design with a " air gap to keep heat from tarnishing the mirror finish.

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!
