GS headers on a MM ??
Hi Dudlow,
The headers will fit of course, the barrels are in the same place and the bottom of the engine/sump is the same, but where the pipe exits, finishes to 'line up' with the silencer, that part will be a No.
You will have to get a stainless steel welder to just adjust the end inch of the outlet for you. I found a man locally who did it for me for a tenner, proper job !!
The hiccup is that the silencer doesn't mount in the same plane/axis on a MM as on a standard GS. The actual silencer/end can that I used was an Enduro genuine BMW aftermarket Akrapovic 'race' can and I ran it without the baffle - not loud, just right.
No worries though, I spent a couple of hours on a bench polisher before fitting my Remus headers and they held their polished finish very well.
A bonus though was the weight saving, you weigh your headers and end can on a set of scales and then do the same for the Remus headers and choice of can, it will be a reduction.
Cheers
