Will a 650 exhaust fit a 550?

[Jackw]

Any help is greatly appreciated. I found a good looking exhaust on Ebay but it's for a 650, same year as my 550, but not sure it'll fit...

I have both a stock 80-82 gs550 and 81-83 gs650 exhaust in my garage and they have different diameter of pipe at the head. However, you're running the 4 valve model of the 550, so it might be different. What i'd do is find someone who has the 83-86 550 and ask them to measure the exhaust spacing and diameter. I can do the same on the 650 here for ya.

Thanks, I'll pull the exhasut off of my bike and take the measurments.

they don't fit, different bore spacing, Bigred went through this last year,
