The OEM charge piping leaves something to be desired with inefficient bends, blockages not optimized for performance. The CTS Turbo throttle pipe increases the entire inside diameter to 2.5" allowing for increased flow and greater performance. The integrated water methanol bung allows for simple and straight forward installation of kits from Snow Performance or AEM. All of the components included in the CTS throttle pipe kit work flawlessly together to provide increased efficiency, horsepower and torque throughout the entire power band and an aggressive race inspired sound.
