I got a flowmaster 40 series with 2 1/2 inch pipe and it sounds good I think 3 inch on a 2.2 would be overkill and you would have no backpressure which would kill your low end power.

i have a gibson 2.5"catback on my 99 noma with dual 2" out back sounds good but verry sleeperish. nice low tone, if you want somthing loud get F.M's. remember bigger is not always better 2.5 from the cat is good but you want to go .25-.5 smaller after the muffler to make back pressure like lowxtreme said, thats what flowmaster told me when i called them.
good luck :cool:

Remember good motor mods for performance will help on backpressure with 2.5" pipe on the 2.2L. And it will get louder.
