Downpipe is OK, but you can't replace the maincat or you will fail. A downpipe is technically illegal but I have never heard of anyone actually failing because of a downpipe.

Get a downpipe for sure. It doesn't affect passing emissions. Get a Catback as well. As for the main cat, it depend on you. Most people get a mid pipe and just switch there main cat on to pass emissions. If you get all 3 pieces you will definately need a FCD because you boost will be 9-10 #'s.
