Ask a Question
  • Is this pipe high-flow (egr-delete) won't fit stock trucks? Better path and flow. I have an HSP pipe that contacts my hood by a little bit, but the design is poor because the EGR and cooler don't exist. Better path again.

    This is egr delete, if you want egr we sell the deviant Y bridge that uses egr and cooler. https://www.rpidiesel.com/products/06-10-duramax-deviant-high-flow-y-bridge?_pos=8&_sid=1cabffdfa&_ss=r

  • It's hard to tell exactly from the picture, but this cold side pipe does include a location for the boost sensor correct?

    Yes it does have location for sensor
