S6 and rs6 exhaust diameter

[Bbflex]

Hi guys, I have a poorly exhaust, does anyone know what size adapters I need for fitting the rs6 exhaust to the s6 downpipes please?

I’ve looked through a thread on here and seen someone using what I presume to be 63mm-50.5mm I think adapters but I just wondered if anyone can confirm it please.

Also both flexis have snapped do I need 55mm flexis? I’ve been under with a micrometer but due to where the car is I can’t get it up in the air at the moment so was wondering if anyone knew the size.

Thanks in advance
