whats the internal diameter of the euro exhaust

[adammet04]

quick question

from the cat back whats the internal diameter?

couldn't find it easily...

looking at exhausts one of them says has a 2.5in internal diameter, just wondering how different that is to the stock one ?

cheers

54mm before the split, and 42.7mm after the split.
