Perrin Subaru Downpipe Thermal Blanket

  • The Perrin downpipe thermal blanket will improve response while lowering underhood temperatures. Thermal losses from headers, downpipes and turbine housings cool exhaust temperatures thus the exhaust loses energy and velocity. This cooling effect reduces turbo response and horsepower. Perrin thermal blankets insulate the exhaust from losing that critical heat, which in turn maintains the velocity of the exhaust gases. Improve power and protect vital under hood components from heat damage with this easy-to-install and economical part from Perrin. The downpipe thermal blanket fits around the tubing of most aftermarket downpipes, keeping nearly all radiant heat away from your engine, valve cover, intake and other engine components.

    The downpipe blanket features three-layer construction, including an outer cover made from silicone-impregnated fiberglass (rated to 500F continuous), an inner layer made of calcium magnesium silicate insulation (rated to 2000F continuous) and silica (rated to 1800F continuous) insulation used to contain the inner layer. Stainless steel rivets are mounted to the blanket and stainless steel wire is supplied to secure the blanket to your turbo. This allows for a simple “lace-up” type installation, even with the downpipe already installed. 

    Downpipe sold separately.
