just make sure the outlets either increase in size or stay the same. So if you get 2.25 inch headers, get 2.25 tp, or 2.5 that leads to 3 inch exhaust. Or you will get major rasp

Agree.

A 60 to 50 mm mismatch will not kill you. But if you can go from 50 to 60 to 70 mm. In other words you are always moving to a lager inner diameter.
