The Agency Power uppipe is made from 321 high grade stainless steel. Completely polished, the uppipe uses 1/2 inch thick flanges for maximum strength connecting to your factory or Agency Power aftermarket header. The AP uppipe includes a new gasket and bolts to connect to the header. The top side of the uppipe connecting to the turbo includes new exhaust studs for a secure fit to the factory or aftermarket turbo. We recommend purchasing an OEM gasket when installation. The all TIG welded uppipe includes a bung for your factory or aftermarket EGT gauge.
The uppipe is designed to replace the catalytic converter in the 2002-2005 WRX and increase air velocity in the STI which has no cat. By replacing the uppipe, you gain faster turbo spool, quicker throttle response, and a increase of almost 10 wheel horsepower.
