yeah you got it, and i was aware of the steel part. I'm just too lazy to write. so what conditions would the stainless corrode? are we talking salty roads? what comes stock on the car?
I assume you are talking about for an exhaust. If you are then it isn't aluminum, it is aluminized steel, and it does corrode. Stainless would be the way to go, but that is much more expensive. And stainless can corrode given the right conditions :)
