T4 exhaust dimension

[Wally]

Hi Bert,
Not sure which dimention you mean?
Are they the 'header' ports that come from the head and are welded to one flange on each (head) side (two by two) ? Then you must realize also that 1700/1800 have a smaller side to side dimention than a 2000cc.
Do you want the outer hole centers?
I' ll try to measure it tonight. Maybe I can give you the measuements for both engine types (I have a 1800 and a 2000 exhaust)
Greetings,
Walter
