Key item in exhaust back pressure control, the GT Extension kit for the Mitsubishi Lancer Evolution X. With the R & D information gained from the HKS EVO X, CZ200S, maximizing the performance from the stock turbine was the primary focus of the new GT Extension kit.
Replacing the factory extension housing, the two-piece, stainless steel GT Extension kit also includes a front pipe that bolts up to the factory catalytic converter.
HKS has been able to reduce the exhaust interference caused by single-port extension housings by using two separate ports for the turbine impeller and the wastegate actuator. The result is a smoother exhaust flow and a reduction in back pressure enabling consistent and improved turbocharger boost response throughout the RPM range.
Manufactured utilizing a lost-wax process ensures durability and reliability.
Tech Tip: Includes both the HKS 65mm Downpipe + HKS o2 housing turbo outlet pipe. Also includes necessary hardware for install. Does not include o2 housing gasket.
Fits: Mitsubishi Lancer Evolution X
