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.*
