Yes you should build 3.5" everything.
I have also posted this article before.

You need to disable ad blocker to view that site. Good article.
In short, in testing a 3" vs 3.5" exhaust they found 10% power gains @ 500hp.
Gains would probably be less at 250hp but there would probably still be gains.

It should interest you more with a turbo setup. Less backpressure is always a goal. But so should be less turbulence aft turbine and maintaining the pressure differential.
If I were doing a 3.5" DP, I'd want a 4" exhaust.
