Ok so a girl friend of mine has bought this R65 (as a learner bike actually, gotta love LAMS) The aftermarket exhaust is pretty loud. So we have a couple of original headers. And I bought a couple of silencers supposedly a direct replacement for the originals from a BMW dealer.. (who I have no reason to believe has screwed me around so I wont identify) Anyway... something is wrong. When I put the headers in the silencers they are too loose...(for clamping up to work. I think. But I dont actually know. I need to get someone with a clue to have a look.. Or take the bits to someone with a clue. I am in Blackburn North. Melb eastern suburbs. Can anyone help?
