This is my 2005 SS. Has a full Exhaust. Also has a Injen intake. Just put in the Brand New OTT Performance Heat Exchanger and also there Stage 1 kit. The kit is a must have for all supercharged Cobalts. The Horsepower and Torque gains are crazy. This is a video of inside and outside the car during the same pull. No traction in first and very little in second
