      Unsure of the year bikes they were on, sure someone on here will know but yes they are the same fit as the 3BN just without the restrictive squish band. I recently swapped my 3BN for a 3MB.

            @kennymurphy97 it definitely gave it more compression as I could feel the bike vibrated quite a lot more. Was going to get a compression tester for a before and after but forgot all about it. I hadn't ridden the bike for a good week or so before changing the head though so can't accurately say if I felt a difference in power or not, although with more compression usually comes more power. I should be getting my new exhaust soon so I can make the most of it.
