ok here is my ordeal, ive been wondering this and also asking around too. Im turboing my ecotec and im wondering what size exhaust to get. I wanted 3" originally, but it wont fit above the rear wheel assembly, so i was just thinkin about dumpin 3", but i heard that 2.5" straight through would work just fine and i know that clears the rear. So, what do you guys think I should do???

2.5" would work fine but 3" would be ideal. many have 3" that clear the rear axle with no problems. just have whoever makes your exhaust bend it up high enough over the axle so it doesnt touch.
