Subaru OEM Gasket for Lower Up-pipe Connection for STi

The Subaru Lower Up-Pipe Gasket is a metallic crush style that is ONE TIME USE ONLY. Replace it every time you remove or upgrade your Up-Pipe or Header. A leaky Up-Pipe pipe gasket can cause a tuner to lose his mind as the boost will not be stable & predictable and will cause the turbo to spool slower thus losing Horsepower and Torque.
Not Available


Part # SUB44022AA170

Works on ALL 2002-2013 OEM Up-Pipes or upgrades that replace the factory pipe (like the PERRIN Up-Pipe.)
