Exhaust system for my 1984 GS1150ES

[Elimax]

Hi everyone:

I hope you're all doing okay. 

I'm having a hard time figuring out if exhaust systems from other Suzuki models/years will fit on my 1984 GS1150ES.  I see ads on Eblag and at vendors for systems I think will fit appropriately on my Suzuki but often I'm not sure if they will, and I'd hate to make a purchase and find out I was wrong. 

Is there some sort of chart or guide for which aftermarket systems are interchangeable for Suzuki models?  It would really help a lot!

Thanks very much.

Pity you’re in Arizona. I have a standard system here.

Not sure but don't think any are direct fit. 

Most will need some alterations to rear mount. 

Think all gsx1100 will fit with some minor fab work
