Mk1 < 98 Exhaust Question

[u33db]

Does anyone know if the bore of all non 16v exhaust systems is the same?

I'm think of replaceing the centre section of my 1.4 with that of 1.2 as some of those didn't have a centre box.

Thanks

C'mon people - xxpected a better response than this!!

If someone would be good enough to go an measure the bore of pipe on their mk1 1.2 that would suffice?
