The Agency Power uppipe for the WRX, STI and Legacy GT is made from polished 321 high grade stainless steel. 1/2" thick flanges are used for maximum strength and durability. The AP uppipe includes a new gasket and bolts to connect to the header. New exhaust studs for the upper flange are included for a secure fit to any turbo. The all TIG welded uppipe includes a bung for your factory or aftermarket EGT gauge. By replacing the uppipe with a high performance Agency Power piece you will gain faster turbo spool, quicker throttle response, and a good increase in horsepower.
