Will 1000G exhaust fit on 850G?

[sacruickshank]

My recently acquired 1980 850G has some exhaust damage on the RH side. Nothing major, but I might have access to a cleaner exhaust from a 1980 1000G.

There are some obvious differences, such as the 850G exhaust has a connected between the inner pipes while the 1000G exhaust is a pure 4-into-2 with separate LH and RH sides.

Can they be swapped or are there differences in exhaust port location, rear mounting points, back pressure tuning, etc.?
More broadly, is there a list of the common parts? I know the engines are different, but everything else looks sooooo similar.

In this case, the Partzilla fiche doesn't help as it only has a listing for the 850GL, so I can't check if frame #'s are the same.

Physically, yes. HOWEVER, ... the bolt spacing on the collars is different by several millimeters.

It might be possible to enlarge the holes to allow narrower spacing.

GL pipes might also bolt up, but might interfere with rear footpegs and sidestand landing locations.

Thanks. I was planning to measure the ctr-ctr distances between the pipes as a check and will now include the mounting bolt dim in my check

Pipe spacing is no problem, just the mounting bolts.
