1980 gs850 stock exhaust compatibility

[Guest]

Couple questions. Would gs1000 gs750 gs1000l gs750l exhaust fit. Also do the different stock exhausts flow differently.

The 750 exhaust stands a better chance. The collars on the 1000 pipes fit bolts that are just a little farther apart, would have to be slotted on the inside to fit the 850 spacing.

Is your 850 a G or a GL? The L exhaust pipes are shorter, have a different sound and might have different mounting points at the rear.

Flow differently? Probably not enough to affect carb jetting.

I know this may be a little weird but I am trying to put stock exhaust back on my 850 for ground clearance. Right now I have pods with 4-1 exhaust and a dynojet stage 3 kit. I will reject as needed. I would like to change as little as possible.

I put 1000L pipes on my 1100G. The rear attachment was different and needed a custom bracket. Also the kickstand doesn't clear the pipes quite right. But it works. Backpressure doesn't seem to be an issue with the shorter pipes; it shouldn't be if the cylinders, cams, carbs, etc are the same between the bikes.
