SB18 is for the OS91sz
SB20 is for the OS91hz
SB19 is for the YS91sr

SB19 is the one you want for the YS91SR
I know the headers are different and I am sure the placement of the internal baffles are different.

You mean I cant use SB18 with my SB19 header or adaptor right? I called friend of mine whos live on the west coast he told me that he used to have SB18 with his OS now he switch back to YS SR91 and still use the same pipe SB18 all he has to do is cap the pressurise pipe and it work fine. just want to making sure that I can use my SR with this pipe.

I am sure it will work that way, but it wont work as well as the intended pipe. All the Hatori pipes are tuned for the specific engine they are sold for.

If you have the 18 pipe just use the header for the SR motor. My friends and Swapped pipes back and fore between the 18 ,19, 20 all the long version. Tuning was like 1-2 click and really couldn't feel a differnets in power. There may be a differnets in the baffling but all felt the same in the air. JMO
