Greddy's new high-flow uppipe for the  WRX & STi is a great modification that will improve boost response and overall low-end drivability. This is a huge improvement especially in 02-05 WRX models equipped with a factory pre-catalyst. The Greddy uppipe is manufactured from full mandrel bent stainless steel, computer welded thick flanges for added longevity, and durability. The Greddy uppipe includes all new OEM gaskets, and turbo studs for easy installation. This eliminates the frequent task of running to the dealer to replace broken and leaky OEM components.

Please Note: This Greddy uppipe is available with a EGT bung.
