Will a gs1000 exhaust fit a gs850?

[Jakobzen]

Hello.

Im the happy owner of a 1979 gs850. The exhaust is in a bad condition, and I've come across a 1979 gs1000 exhaust up for sale. Before I place a bid, i would like to ask if anyone knows if it fits my bike?

thanks in advance,
Christian

Yes, it will physically fit, but WILL require modification.

I had a 1000 exhaust for my 850, found that the bolt spacing at the head was larger on the 1000, so the holes in the collars would have to be slotted.

Fortunately another member (dogma) had gotten a set of 850 pipes for his 1000. When he heard of my situation, we decided to compare and eventually swap systems.

Thank you very much for the quick reply - I will keep looking for an original gs850, then.

Are the headers in good shape? If so, you can cut the pipes off and weld a sleeve on to fit an aftermarket exhaust. The ones I bought came with a sliding bracket so it was easy to mount. Takes a bit of Mcguivering but it looks original.
