BANKS 47784-B MONSTER 4IN. EXHAUST SYSTEM-SINGLE EXIT-BLACK 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 Cerakote Black 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.
