The Injen Pressure Piping is fabricated out of mandrel bent out of aluminum for maximum weight savings over heavy steel piping, and uses special MR technology to maximize flow into the motor, while not affecting the sensitive mass air flow sensor. This two piece kit replaces the OEM piping from the turbocharger outlet to the throttle body.

Please note- Injen made a wonderful kit with this piping set, however, they use silicone couplers that are too short, and easily pop off with the engine movement. We solved this problem by making a upgraded coupler kit that has T bolt clamps and longer silicone couplers. In testing on our 2009 Cobalt SS, we never had a pipe or coupler blow off again with our upgrade kit! So dont risk losing power and engine damage with a pipe that is leaking or blown off! Add the MPx coupler upgrade kit from the above option and you'll receive two 3" long couplers and six T-Bolt clamps for your install!
