GS750 - GSX750 Exhaust compatability

[Anonymous]

1982 GSX750EZ. Is a GS750 (8 valve head) exhaust system compatable with the GSX (16 valve head)?

No replies and I have also searched with no success. I would like to know if a 1981 GSX750 exhaust will fit on either a :

1977 GS750B?
1977 GS750D?
1979 GS850GN?

or does anyone have the diameter of the 16v exhaust port so I could compare the size with either the GS 750 & 850 for compatabillity.8-[.
Thanks.

Same problem just in reverse

Hi Freddy
Did you ever find out if a 1981 GSX750 exhaust will fit on either a older GS750?
I've got a 1982 GSX750L (TSCC motor) and need to find a exhaust to fit it.
I'm not too worried from which model it comes from as long as it's quiet and fits... (For the German vehicle testing).
I've heard that the header pipes from the GS are not compatible with the GSX... can you confirm this?

I can tell you that the 81 won't fit the 70's era 750 bikes...different cylinder spacing.
