Hi, I just bought a new 05 base coupe in arrival blue. Nice car, just not enough umph. You guys probably don't know, since you are running around with superchargers. Anyway, I was looking through ebay for some simple cobalt things and it hit me that these cars are on the Delta platforms. So, I went and typed in for a Saturn Ion. Well, I came across several intakes as well as exhausts. Complete cat backs even. I was wondering how much of the Saturn Ion stuff will fit onto the cobalt? How similar or different are these cars? Do you think a cat back for an Ion would fit a cobalt if they run the same platform? Any help to this subject would be greatly appreciated. Or if anyone knows where to point me that would be great as well.
