BANKS 47784 MONSTER EXHAUST SYSTEM 4IN SINGLE EXIT-CHROME TIP 2007-2010 GM DURAMAX 6.6L LMM

Cuts backpressure by nearly 57 Percent. 4-inch constant-diameter DPF-back system. Patented SideKick tip cools temps. Includes Huge Polished Chrome Patented SideKick tip.

The Banks Monster Exhaust is engineered using computational fluid dynamics (CFD) software then tested on both dyno and on-road.

Reducing backpressure allows the engine to expel spent gasses with less effort. Less pumping loss means more horsepower, lower EGTs, and improved fuel economy.

The Monster Exhaust system cools while flowing up to 80 percent better than stock! Cooling without killing flow is a major challenge. But the Monster Exhaust wins on both counts thanks to its mandrel-bent constant-diameter tubing and huge Ob-Round patented SideKick tip. The tip is the key. It's unique shape mixes hot exhaust gas with cool ambient air. And, it keeps your trailer safe by directing exhaust gasses to the side.
