The Greddy high-flow uppipe for the 05-09 Legacy GT is a great modification that will yield improved boost response and overall low-end drivability. The Greddy uppipe is manufactured from full mandrel bent stainless steel and computer welded with thick flanges for added longevity and durability. For ease of installation, the Greddy uppipe for the 05-09 Legacy GT includes new OEM gaskets and turbo studs, eliminating the frequent task of running to the dealer to replace broken and leaky OEM components. This uppipe is available with or without EGT bung. Though the 07-09 Legacy GT does not have a cat in the uppipe like older models, a free flowing mandrel bent uppipe will still improve throttle response and drivability. All Greddy uppipes includes replacement gaskets and studs, making them the best value for this type of modification.
