you mean wheel centre bore? If so then all corsas are the same, even the 1.0 12v, they are all 56.6mm centre bore.

Ah right, well i dont know which end of the centre section you are asking about, but lets assume you mean the backbox end of it.

The 1.0 12v, the outer diameter of the centre pipe is 42mm, and the inside diameter of the BACKBOX is 42.5mm to fit over it.

On a 1.2 16v, the end of the centre section is 45mm outside diamter, and the inside diamter of the bacbox to fit it is 45.5mm.

Hope this is of some help.

I believe they'll sit on the same exhaust hangers, as they are in the same place. Looking at the info i have here, it LOOKS like the end of the cat downpipe sits in the same palce on both, but i cant be 100% on that, it looks very close.

The pipes are still different sizes though, your cat section on the 1.0 is still only 42mm outside diameter, the 1.2 centre section will be larger at 45mm. You'll have that same problemat the bacbox end of it aswell.

In short, it'll sit on the hangers in pretty much the right place, but the pipe is physically bigger and will need bodging of some sort to get it to mate up.

Obviously the centre sections im looking at here have diff part numbers and everything.

1.0 12v - 9202076

1.2 16v - 9128616

Providing you the 1.2 16v straight through pipe is the standard bore size for the 1.2/1.4 etc you will be able to get it to fit your 1.0 12v. 12v's have a small piece of conneting sleeve that goes between the downpipe and the mid box section. All I did with mine when I fitted a 1.2/1.4/1.6 centre on mine was connect it to this small sleeve and it went straight on. If you get under the car you'll see the bit I mean You will need a 1.2/1.4/1.6 backbox though as Dragon said
