The 10-12 Subaru Legacy GT PERRIN Downpipe Thermal Blanket will improve response while lowering under hood temperatures. Thermal losses from headers, uppipes 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.The shape of PERRIN downpipe thermal blanket specifically designed to fit over all PERRIN downpipes, and most aftermarket downpipes. Larger diameter ones will work, but the blanket may not cover the pipe completely.
