<DIV><SPAN class=150065614-27092003><FONT face=Arial color=#0000ff size=2>If you
look into the end of the pipe, stinger end, you can see the last baffle and the
two exhaust holes 180 deg from each other at the outer edge of the baffle plate.
You can open these up with a drill going in thru the stinger or put a couple of
additional holes in the baffle. As it comes, there's just a little too much back
pressure which reduces power about 100 rpm. Opening the baffle up will increase
the noise a bit (about 1 db. with the sound meter mike focused on the exhaust),
and bring the power back up by getting the back pressure where it needs to
be. The only thing to be careful of, is if you open up a couple of new holes 90
deg. to the existing ones, don't get to close to the edge of the baffle plate
because you can drill out the pins that hold the plate in the pipe
body. Putting one additional hole right in the middle of works also.

or can you get to the holes from the pipe connection?<BR>Buddy
