TD5 Exhaust dimensions

Hi all. Can anyone advise me what the diameter of the TD5 exhaust is please (I believe it may be 2.5"/63mm)? Also, if anyone is able to give me a reference point on the chassis/body as to where the front flange sits (the 2-bolt one?) that would be really useful. This is for a project where I think this exhaust may be useful but I'm reluctant to buy one without checking first!
