How hard and what will I need to switch to dual cat? Im guessing just a dual cat y-pipe and two converters? Reason being....I will be getting a new engine...and Im worried about passing the sniffer test...the guy at the inspection station said that I should convert to dual cat...and I shouldnt have any problems. I'll probably be going with the Fastburn 385 with the HOT cam.

I doubt you'll see much(if any) improvement with dual cats versus a high flow 3" inlet/outlet cat. The dual cat set-up has significant bends that are very restrictive(vs the single cat set-up). If you do decide to go with dual cats, you will also need the special mounting brackets for this application(I believe SLP still sells these).
