Removing cat and res???

So I went to a custom exhaust shop in MA, I asked for better sound and flow, he suggested to delete my second cat and my res... Is this the best options? I've seen alot of people do different combinations of deletes and have heard alot of opinions.. Any one with helpful opinions and not just bias
