There may be a clearance problem with this muffler.The 937 is the short header version I think.

You really need the 946 or the SB19FH

Thanks for ur answer !!

Can u tell me measures of SB19FH ?? I'm not able to find them to compare with the 937 :(

bye, Jack

Clearance or not you should get the proper pipe that is tuned for the YS SR..... I don;t know if the 937 is but the SB-19FH is tuned for the SR.

hi Bob

937 is tuned for the SR but the header is 6mm longer then SB-19FH !

[Finless]

If the header is longer on the 937 then you are OK. SB-19FH fits fine.

Jack,
That is usually the difference between the USA SB designation Hatori mufflers and the 3 digit mufflers that Hatori makes for the rest of the world. The header length is the only difference I have found over the years. Richard Sabin at Hatori USA just has Mr. Hatori put a different inlet on them.
