Hi Paul, 1st time on here in ages and saw this post,
Here goes , the OD at just before the head flanges on my 4xv are 35mm.
Hope this helps ya.

Many thanks
I have a set of headers that are being refurbed I had doubts on their fitment as the pipes are a fair bit
narrower than on the EXUP 1000

Im sure I heard somewhere that they can be made to fit, Think you may have to spread the pipes out a bit, ATB .

Poss they could fit but they're nearly 4mm less in diameter than the FZR items. Don't know what sort of impact that would have on performance
