PA resident get in here

Where outside of philly are you? I'm in delaware county...
Anyway, I really don't think that you will have a problem, as long as you don't get a dick for a mechanic to do the inspection. As long as the cats are there and working properly and no lights, should be good. If you car is OBD2, there is no sniffer test.
 
if you find a shop that the mechanic will skip the visual part and let it go you will be fine. there are a bunch in our area that have been hooked up to the machine and passed with no cats at all.

99gt- slp longtubes, slp o/r xpipe, slp catback
00gt- bbk longtubes, bbk o/r hpipe, mac catback
96 cobra- dr gas o/r xpipe, borla catback
