I know this is minor and really doesnt mean a thing at the end of the day. I just want to confirm.
Ive read in some places and some have posted up that its actually 63mm dia piping.

can anyone confirm this?

is it actually 60 or 63?(most places selling say 60mm ) but some owners say otherwise.

any help is appreciated. not looking for a debate. i know its not going to change anything. i just want to confirm the actual specs.

thanks
