Default Exhaust size? - 2001 1.8t

My son has a 2001 B5 A4 quattro with the 1.8l Turbo engine that I help maintain.

The front flex joint was split so we replaced the front pipe a month ago with a Bosal replacement

I did not have a new exhaust sleeve clamp at hand & it's leaking!

Unfortunately I did not measure the size of the exhaust pipe before my son went away on an internship & I threw the old exhaust section away. Anyone know the size of the OEM exhaust pipe so I can order a new sleeve clamp? is it 50mm or 55mm?

Thanks in advance

I am pretty sure it's 55mm and the smaller 50mm fits the V6 pipes

Thanks JSChick, after looking at Techtonic's & ECSTunings' web sites I am convinced it is 55mm. I've ordered Bosal's 265-827 from the latter anyway...

Just strange that Bosal do not list this part against the 97-01 A4 quattro though... I guess we will see.
