Does anyone know of a company that makes insulation to cover the up pipes, turbo (exhaust side) and the exhaust down pipe? I would like a pre-fabricated kit sized for the piping on the 7.3L. I would prefer not to use a do it your self wrap with ss/hose clamps. The firewall and passenger side floorboard gets over 140 when towing. Yes my firewall insulation is intact. I am familliar with marine exhaust lagging and am looking for something like that for my truck.
