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
