Up-Pipe Passenger Side with Gaskets (2001-2016) - Chevy

  • Sale

The Duramax engines were built with great potential. Part of that potential is restricted by the factory up-pipe that has small diameters and a large indent which inhibits smooth & steady airflow. This GDP up-pipe has a larger piping diameter to support more air volume, plus no more indent that disrupts smooth consistent air flow. The result is cooler engine temps and a healthier running truck.
