Paul,
  Which Beetle used a tangential muffler? The only one I have seen had a
stamped tubular housing across the back of the car and two pressure bleed
tubes out the back. Inside I seem to remember a straight perforated tube.
Was there a tangential model as well?

The pipes from the engine entered the tubular housing across the back of

the car on a

tangent. Don't confuse the tuned version we have been discussing with the

unturned

version used by Tracy, Dave and the VW. BTW the interior perforated pipe has
been found to be unnecessary.

Later VW models used a "semi tangential design, with the lower pipe (from
the fwd
cyls) entering roughly tangentially at the bottom front of the "tank" made from
two stampings joined at a flange (perpendicular to the plane of the road and the
long axis of the car).  The rear cyl pipes were not really fully tangential
any more,
and the outlets were moved up about half way to the middle.

The OLD VW mufflers, like pre63 were a pure circular "can" muffler with all
inlet
and outlets tangential or very nearly tangential.  Adding the "little heater
boxes" on the
later 'fresh air' heating systems forced a change in the rear cyl (upper)
input pipes, and
they went to the two part stamping for the can , I assume because it was
cheaper than
a piece of lg tubing.

The Sqback, Fastback (Type 3s) never used this exact muffler.
