When installing aftermarket manifolds or tubular headers on your 2007.5-2008 LMM Duramax Diesel you will notice that you will also have to reroute your EGR cooler line because of clearance issues. We have simple kit that will allow you to re-route your cooler line and allow the use of larger aftermarket exhaust manifolds and/or headers. Kit comes with everything needed to install.
This kit works well with RDL Cast Flow and PPE Race Manifolds by eliminating the coolant plumbing at the rear cover and directing it to the thermostat housing.
Fitting configurations and hose lengths can be adjusted by installer for the best fitment.
