I have a 82 cb750k dohc with the original 4 into 4 exhaust. I want to put on a 4 into 1 or a 4into2. Would i need to change out to bigger jets and how to you know what size to replace with? I will really appreciate it if someone can help me out with this. thanx

Won't know till you put it on. I put a new exhaust and even a set of stacks on my CM400 and she runs like a cherry. No jetting needed. I just have to let it warm up for a few minutes or ride it really easy on the throttle before I rip into it or it coughs and bogs. Once she's warmed up she's good to go.

depends on the pipe, what 4 into 1 are you thinking about? what 4 into 2? what jets do you have in it now?

If you use a cb750F stock 4 into 2 then no jetting required.
