Tuned pipes for dummies....feedback sought???

[Fletcher, Richard]

Best thing to do is to insulate the pipe from the mount and clamp or O-ring.
Best material I have found is high temperature RTV gasket material. I make
my own using automotive high temp gasket material rated at 350 degrees and
laminating high temp RTV onto it by placing two parallel pieces of 1/8 balsa
spaced about 4 inches apart on the automotive gasket material and then
squeegee on the RTV. I had to develop this technique for mounting canisters
and pipes on my gas engines which run even hotter then 4S engines.

help????

I have a new Arresti III that will be using a YS 140 FZ and the new coupler
from Central with an (enclosed) ES carbon fiber pipe and the Hyde ARIA
mount.	Merle Hyde says the pipe needs to be pretty flexible in mounting to
avoid header breakage. He also warns to tighten the hyde mount screws
aggressively.

	My thought was to mount a single clamp on the CG of the pipe with a
Dave Brown hush clamp pipe mount.  (O ring retention on a composite clamp) I
have used this mounting style very successfully on a Greve pipe / Webra 145
combo, but have questions about the durability based on what I hear about
pipe heat increase when running a 4 stroke.

Can anyone tell me whether they have experience with the Dave Brown mount
and four stroke pipes?   Do carbon fiber pipes get hotter than aluminum
ones???  How do you typically retain a carbon fiber pipe without worrying
about pipe distortion?

Depends where they are.  If not too far in from the charge end, a mandrel
8-18" OAL from 3/8" steel round with about a 15 degree kink in it 2" from
the(to be) rounded end or so clamped in a vise works reasonably well for
wheedling them out--kind of like the paintless dent removal guys use.  There
are also sheet metal suckers--but I'm not that familiar with them.  Or turn
the dent toward the fuse--dents do not affect performance detectably.
