Hello.

I would like to weld up my own down pipe on my a3. 

I need to buy a flange so that I can get started, I dont have time to take the exhaust off and measure it myself. 

Would anyone know what size of flange I would need for my turbo wastegate? 

As far as I know my turbo oem no: 54399880048

 

Thanks in advance.
