actually have one (698) sitting on my shelf at home. It is the same length as
the 693. The rear chambers appear to be the same as the 693. The difference is
the front portion. I think on the 693 they gained volume ( over the
692) by increasing the length of the front 15 mm pipe so that the
overall length went up to 530mm. On the 698 , its overall length is 530
as well, rear chambers the same too, but as I mentioned it is the 35 mm
section that is now longer towards the front. The pipe has a lot more volume
now. I have always felt the 693 was 'choking' the Dz a little, even
though I have tremendous power already.</FONT></SPAN></DIV>

have not run it yet, but I am hoping it will make things a little quieter
and maybe gain some more power. It may even change that Dz note
too.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Looking at a pipe for my YS DZ. Does
anyone know the differences and pros/cons when comparing the Hatori 692 to
the Hatori 698? From the pictures they look identical except that the
698 is much longer (530mm compared to 380mm). Both are 35mm in
diameter. Are there just more baffles in the 698 to make it
quieter?</FONT></DIV></BLOCKQUOTE>
