Mig welding stainless is ok if they are using stainless wire and argon, technically it should be purged too, but doubtful any shop with just a mig would do that.

A lot of shops will just use mild steel wire and (gas argon/co2) mix to weld on stainless exhausts, this you really want to avoid since it will rust easily.
