HKS EVO GT Extension Kit

Product Description

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, and gaskets needed for an easy installation.

Fits: Mitsubishi Lancer Evolution 8, 9
