Monster™ Exhaust Head Pipe Kit by Banks®. The turbine outlet pipe is one of the biggest restrictions in your Duramax’s exhaust system. Replace the stock pipe with this free-flowing Banks outlet pipe. Don’t let the factory turbine outlet pipe - a part that was designed by an engineer who was apparently more concerned with low cost and ease of installation - choke your truck’s exhaust system to a fraction of the engine’s needs. You’ll immediately feel more power off the line, better hill climbing, and better fuel economy to boot.
- Stainless steel for long service life
- Reduces back pressure at the turbine outlet
- Boosts horsepower
- Reduces fuel consumption
- Hardware included
- 5-year limited Warranty
One of the biggest restrictions to unleashing your Duramax engine’s power is the skinny, convoluted downpipe. This pipe connects the turbocharger outlet to the exhaust pipe. Even if you upgrade the exhaust system with pipe the diameter of a sewer, you’ll still have backpressure that costs you power and increases fuel consumption. This mandrel-bent stainless pipe will uncork that last restriction.
Reduced backpressure means you’re not pushing the exhaust downstream as hard, which saves fuel. It’s better yet: reduced pressure means better scavenging of spent exhaust gases from the cylinder. That in turn means more air gets into the cylinder on the intake stroke, improving power at the same time.
Banks® Exhaust Systems are US-made, each unit is precisely dyno-tuned and shaped to fit selected model and production year vehicle and deliver great increase in torque and horsepower. Even the polished muffler tip is built with T-304 premium stainless steel. Each exhaust system has an easy bolt-on installation and requires no modifications to the vehicle for the installation.
