Anyone know the thickness of the downpipe section on say a Mk2 Astra GTE 16v?

I keep hearing people say you need a 2.5" system ideally on a Nova 2.0 16v. Just wondering, if the downpipe isn't 2.5" it would make mating the mid section pretty fiddly

Cool, do you know any Perfomance exhausts that are 2.25"?

Then I can get a midsection and get them welded together at a proffesionals :)
