4 inch exhaust

Forgive me if I sound like an idiot. But I have a 3 inch down pipe going to a 4 inch stack and I want to get ride of the stack and put a 4 inch exhaust out behind the rear tire. My question is can I just buy a 4 inch cat back exhaust and bolt it from my down pipe or do I need to order a new turbo back exhaust? I just don't want to order a cat back and not have enough pipe or something. Thanks!

Amazon has them too, but I know if you did get a turbo back that down pipe would be relatively easy to sell
