I am pretty set on the catback I want to get... I have dumped magnaflows right now but those are goin. I want to get a mac cat back (http://www.stangmods.com/MAC-Exhaust-p/00416-tk9624.htm) but I was wondering if there is a mac catback that is stainless, or if the basic "bbq" rust proof paint stuff would be sufficient for a long time. Thanks for the help.
