Guys,
I tried the cone from Jegs on my original
Tangential muffler. Observers said there was no noticeable difference. I am
working on a "Swiss" muffler now, and I'm planning on trying
it again.

p.s. I am closing in on the 60 hr mark
now. All systems good. Cooling is still working a little too good 145-150
degrees cruise. Waiting for hot weather!

I have often thought that perhaps two of
those cones in a 3" tube might provide sufficient lowering of the noise
level. However, having two tubes, that would mean 4 cones and a bit
expensive.
Tracy has had very good luck
with the Flow Master Hush Power II. It has about the best streamline
combined with good sound suppression. Tracy reported it not quite as good as the Spintech
on the sound suppression but better with less drag (and less cost).

Lynn, you may have the small idea for a round spintech in your
Borla. I had the thought after looking at the cone in Jegs hot rod
catalog. Has anyone tried one of these cones, the smallest one is 3"
in diameter and is $69. If it would stand the hammering it could be
mounted in a 6 or 7" piece of stainless pipe and should not be weight
restrictive. JohnD

I welcome any and all comments and
criticism, as I stated, I don't have a clue how this will work. JohnD
I think this will be rejected out of
hand. Just enough flow to get off idle but no more. So now we have a
4" Borla stainless.
For the lower RPM the smaller core
diameter would be OK. But the least amount of restriction possible is far
better.
The Spintech worked. It just had a bad
shape. How about a round Spintech?
