RE: [DMCForum] Mufflers..

["Dave Stragand" <dave.stragand@xxxxxxxxxxxxxxx>]

Like the classic 'turbo' mufflers?  These types were designed to
overcome the high heat in turbo apps by the diamond baffle pattern.
They can still be pretty loud.  I had them on my Chevy and didn't like
them much.  They tended to be very raspy under load.  I much preferred
the glasspacks I put on later.

I tried every muffler manufacturer two years ago looking for something
for my D.  The only ones I could find that fit were either the Walkers
or Supertrapps.  It is a very tiny muffler -- 9" body -- and not much of
anything else would fit.  

I was going to repack another set of 21959's as they were only like
$9.50 each last I checked.  It was actually the Walker tech support
fellow who recommended the carbon-fiber packing trick.

Thanks for the info Dave..

I was looking at some of the "chamber" muffler
designs.  I know they are not as free-flow as the
"packed" mufflers, but I would guess they make less
noise..  They also don't ever change their noise level
(packed mufflers tend to wear out).

Any comment on that idea?
