Agency Power Stainless Steel Uppipe Subaru WRX/STI 02-07

Agency Power

AP-GDA-173


There is no other company that makes high quality, power producing, and purposeful products like Agency Power. With an amazing exhaust system, it only makes sense for Agency Power to offer their all new uppipe to Subaru WRX and STI owners. This 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 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. The Agency Power uppipe is designed to fit on all Subaru WRX and STI from 2002 and up. For questions on fitment, installation, or the product, please contact a sales associate.
