I dunno - Cali is pretty strict about that sniffer crap. You should probably have a cat as close to the header as possible for hot exhaust to super burn any extra hydros leaving the engine. I made a flanged cat and flanged the exhaust and made a pipe to fit also. The cat comes out in 15 minutes on a lift and I have a pretty straight exhaust.
Sounds like you don't have much in the way of equipment. Good luck.
