I would be thrilled if a header, pipe and GMPP catback gave me 20hp, hope it does. However without seeing real numbers I'm inclined to think 8-10hp on the ~145hp 2.2L.

I'll let you know for sure how much HP it would be... I'm ordering my GMPP Touring exhaust today and the guys are going to dyno it for me before and after install.. then in Nov. I'm getting the header / down pipe and CAI installed each will be dyno'd before and after install...
