If I were to replace my exhaust only to the cat and leave cat-back stock, what exact sizes would I need and what parts would I have to purchase? Other guy's exhaust headers and a downpipe with high flow cat and ubend delete? And if I do that , how would i make it so it fit onto my stock piping if the piping in the headers / downpipe are going to be larger?

Get the kit that uses a 2.5" exit on the DP, they offer one. It tapers from the 3" tube down to the 2.5" after the cat.
