Banks 48631 Monster Exhaust Head Pipe Kit | 01-04 GM 6.6L Duramax 2500HD / 3500HD LB7

The turbine outlet pipe is one of the biggest restrictions in your vehicle's exhaust system. Pushing air out of the turbocharger wastes power that should be going to the drive wheels. Monster turbine outlet pipe provides a restriction-free path out of the turbocharger for quicker response, higher boost and more power. The larger diameter increases exhaust flow, producing more torque and horsepower.
