Hi guy's,
quick question, would an R1 4XV exhaust fit on my 92 RU?

do you mean the end can, headers or complete system?

BTW, a bit of an introduction in the lounge might help

Hi Stig,
I have been offered the headers from an R1, my RU has had the exup cables ect removed , even though the valve is still within the exhaust.
Rather than taking the valve out and welding up the hole I thought the headers might be another option.

Ill organise a better introduction and pictures in the lounge once I have a ticket on the fighter.
Thanks for the assistance

the drop from the exhaust outlets to the underside of the sump is different as the R1 has a stacked gearbox...could probably be made to fit with a lot of work but dont know anyone whos done it

One positive tho' is that all the internals for the R1 will fit the exup. I seem to remember that the cables may fit too...either way if you have the ends for the cables its possible to remake them in the FZR sizes

Using the FZR headers without the valve in will leave a big hole in the power delivery and you'll lose all that famous low down drunt that the valve was designed to produce in the first place
