One thing you could *try* that might work is to make your own 'resonate
chamber.' In the back passenger side of the 'z'-tube, drill and tap a hole
for an NPT fitting, then attach a decent sized hose (at least 1/2" dia. I'd
say) to the fitting, and run it to a chamber made of lexan or sheet metal or
something (maybe a 4L jug of something ... milk, oil, antifreeze?) ... you
could vary the volume of the chamber to find the optimum volume that cancels
the vibrations...(if you really had the time and $$ you could probably vary
the chamber size to get an optimum hp, maybe gain 1-2hp)...
how's that sound for a fix?
:)
