XR 650 Exhaust

[Sage]

Hi All

Could any one tell me the OD of an XR 650 header pipe which fits into the silencer, the large single tube that goes to the silencer, not including the gasket?

Hi All XR 650 owners, could one of you please do me a favour and meassure the diameter of the large single pipe from the headers where it goes into the silencer pipe, just need to know the OD for a project I might have.

Thanks to anybody who might care to help.
