Kawasaki 750 Ss 650 Sx X2 Coffman Exhaust Pipe Chamber Coupler Manifold on 2040-parts.com

This is actually a rare 750 pipe.  The manifold has the same engine bolt pattern so it can be used on a 650, 750, or 800.  The upper portion of the manifold has a four bolt pattern instead of the normal three bolt pattern found on most other pipes so this head pipe and manifold are not interchangeable with other head pipes or manifolds.  The head pipe is also a little taller than the 650 version of this pipe.  I think this pipe was meant for the 750SS.  I ran it in my X2 for a few years but I had to glass in a little bump in the hull to get it to fit (see pics, makes your ski look way meaner!).  I assume this would also fit into a 650SX although you might have to do some light trimming to the baffle in the hood. The manifold has three cooling taps.  One is plugged and one needs the fitting of your choice.  The expansion pipe coupler has two thinner spots.  I ran it like this with no problems.  If you want to replace it on the cheap just go over to Napa where they sell large diameter hose by the foot.  Before installing this on my ski I sanded all mating surfaces on a sheet of glass so they actually seal properly.  I used Threebond 1211 sealant instead of gaskets and never had any leaks.  The matting surfaces need to be cleaned of the old sealant but besides that they're in great shape.  The smaller hose clamps for the head pipe to chamber coupler are not shown in the pics but will be included.  Brapp hard my friend!
