Thinking about picking up a used N54 BMW (not sure what yet). A couple I've looked at have bolt-ons (FMIC, downpipes, intake, charge pipe), and I'd like to see if people have experience bringing cars with these mods in to have them serviced at BMW Bel Air. I'm not necessarily averse to removing mods if the car is what I'm looking for, but I'd like to see how sensitive they are to this kind of thing. I certainly don't want any part of my warranty in jeopardy.

I've heard folks say some of the SAs are pretty mod friendly, as long as it's nothing crazy, just didn't know if there's any evidence to back that up.
