Are the exhausts for different models interchangeable?

[Guest]

Hi

I'm looking for an exhaust system for my GS850G 1986 (same as 1983).
I'm going to hunt around for something second hand, and so was wondering if I can use the exhaust from other GS models, thus widening my options.

Any thoughts on whether the same exhaust is used on other GS or non GS bikes?

Thanks

750 upwards headers will fit but you might have to play around with mounting brackets for the silencers.

8 valve 750 and up only. 16 valve will fit at the head but will hang lower than stock. For an exact fit 83 up 850G 1100G/Gk will fit.

How about 550's

How about on 550's, I have an 81 550L that needs and exhaust, well a bit more but that's the main hang up, i was wondering if other years will fit? Im sure it has to be a 550 exhaust, can it be any year from 77 to 82, 80 to 82, only a 81 or just any 550, even up to 85? thanks

8 valve only 550/650 will fit. "L" models excluded. (may fit, but an entirely different and IMO crappy exhaust note) 83 on 550 were 16 valve engines and the port depth is different iirc, and the bikes had completely different frames (boxed vs tube, and we're mono shock)

I have a complete exhaust off of an '80 550E if you are interested.
