Dear all, is it possible to attach an 907 i.e. exhausting system on a 906 (model 1990)? They look different (black (906) vs. black / silver (907)), but that does not mean too much anyway. Thanks a lot and all the best, Hardo

Without any problem.
No matter, the first series of the 907 had the whole black mufflers too.

Both have same frame(w.rear footpeg/muffler holders) and same 904 engine(same headers), so they should fit.
