• Diesel Mafia Performance 17-20 L5P Downpipe Kit



    This Product is to be used for Off-road Race applications ONLY!!

    3 ½” Down Pipes


    If you're Installing an Exhaust system, we highly recommend doing the Downpipe, as the SCR behind the turbo will plug up and cause drivability issues.

    Turbo removal is required for SCR removal & downpipe installation.

    Turbo removal requires most of the EGR system to be removed, so it makes sense to do the EGR Fix Kit at the same time as well.

    *The EGR Kit comes with all necessary GM Gaskets for turbo re-install.*
