|
|
Hello guys!
I've got a question regarding the exhaust System of the YB9.
When I bought the bike, it came with a pair of stainless steel headers and a carbon fiber exhaust (well the manifold appears to be stock and has a Bimota stamping on it- the exhaust has no stamping). Both fit good together- but this setup is too loud!
Apart from that I've also received a pair of titanium headers (to be mounted with springs) along with the original exhaust.
The problem starts with german MOT- since I'll have to mount the original exhaust, which, eventhough both parts are original Bimota, doesn't seem to fit with the stainless steel manifold,
On the other hand mysteriously the Original muffler suits the titanium headers relatively good (mounting points- etc.)...
What I trying to figure out is: Did these bikes come with titanium headers as an option form the factory, or is it just an aftermarket (presumably hand made) system?
These titanium headers have no particular stamping on them!
Does anyone know if there where different versions of the exhaust manifold between the SR and SRI? I suppose the muffler stayed the same during the whole range of production.
I'll try to post some pictures of both systems later today. Unfortunately I haven't managed to take any yet
I'd surely appreciate some insight and comments I couldn#t find much about this on the internet.
Maybe some pictures of the original exhaust system for the SR would help- if someone can post it.
Best regards,

I second that....End cans Bimota offered options of Carbon fibre for a lot of Bimotas....but never titanium headers....they are more famed for always using stainless steel headers....and normally stamped with a "b" or a metal plate welded onto the connecter ends of the headers with a "b"....Arrow also made systems for Bimota in the 1990's.... |

Hi
The headers are the same for the SR and SRi . My new Bimota OE headers (via Germany) are labelled "Krummer YB9SR/I" and have the part number 502815020 and are stamped 281 b .
These weigh 3.6kg, are one piece and take a link pipe with a 52mm ID.
Had some issues trying to upload photos otherwise would have done that for you. What do the Ti headers weigh?
Regards
