Head Pipe Diameter

[*Nemesis*]

I am not near my bike at the moment and wont be for a few days. I am needing head pipe diameter for a 2015 R3R, does anyone know the specs or can measure theirs for me? I did a search but didn't find anything. I am in talks with a reputable exhaust company to may be able to make a slip on exhaust for our Rockets, hopefully at a decent price. Thanks and I hope someone can get that info for me.

the outlet pipe from the header section is 41.5mm internal diam. and 44.5 outer diam. (1.5mm wall gauge) on a 2010 roadster. the exhaust header has not changed since then. actually its the same part as the standard rocket iii header

IF U ADD 41.5MM AND 1.5MM IT EQUALS 43MM (sorry for caps) so u either made a typo or a little off on measuring.
