IS THE DUCATI 750 SS 2000 , FITS DUCATI 600 SS

there is a section within the tubular structure which the clocks sit in where this air sensor with rubber housing sits. Directly infront of the key barrel but behind the oil clock it is a flat piece of metal attached to thesemi circular section.

I found some pipes that I'm interested in and am wondering if anyone can tell me if they'll work/fit correctly. I've done a bunch of searching but can't find the info for sure. I'm trying to use both low and high Termi slipons that are carbie 750SS specific on my 900SS/FE header. I've heard that there may be a diameter difference and possibly a length mounting or angle difference that will cause problems but I can't find anything that says for sure any differences or measurements. Anyone done this? There must be a difference for there to be two part #'s, but I can't figure out what they are. Thanks in advance for the input!,I think there are some dimensional differences in the headers as I think the 750 engine is a bored out 600, therefore physically smaller than the 900, but I would think most slip ons are interchangeable for both models.,,,
