exhaust size

[win]

Hi All
Does anyone know the exhaust diameter of 803, 1098 and 1275cc.

Thanks and regards Win

The original exhaust is something like 1.25" I'm guessing for 803/948/1098 cars. There never was a 1275 - so any exhaust used will either be the standard - or a specialist item. Suggested size would be 1.75" - although 2" may be better on a highly modified 1275.

my 'large bore' exhaust is a shop bought item, and 1.5 inch in diameter if it's any help.
