2.2 w/ lsj exhaust manifold
it would be better than nothing... but you'll gain even more when you get a cat-back... the piping on the 2.2 is tiny. See if you can find a stock Sport or SS cat back that someone is getting rid of... it would be good for the 2.2
its is a great and cheap upgrade but do the whole system, when I changed mine it was a nice difference imo, dont know if you have seen the difference in the two but its a night and day difference, here are some pics of the two side by side from when I upgraded

I want to see numbers from a car with just the intake mod, ss/sc full exhaust system and intake manifold from 2.4, I bet its some good numbers and not to much in the price department. Or if someone has done this and I cant find it please post if for me
