[DeTomaso] Muffler Opinions

[David & Marilyn Bell]

JT was actually an intimate conspirator to the muffler gutting written up in
the link below.  The addition of the high tech exhaust flow-splitter (the
short piece of angle iron) was JT's idea.  And now that I think on it, the
two pieces of angle iron that went into my mufflers originated from JT's
scrap metal pile.

Between the two of us, we've probably cut apart and rewelded 5 or 6 pairs of
Pantera mufflers.  It's only the resonator tips that are in question as we
have yet to butcher any of them up.

>The construction of the resonator tip is different than I thought.  I
assumed that the ceramic(?) material in the tip's end continued through the
resonator.  You are correct that it only positions the metal pipe inside the
resonator tip to the center.  The perforated metal pipe is exposed the rest
of the length.

>However, now the perforated pipe extraction task is potentially easier.  A
hole saw could be used to drill out the ceramic material that holds the
perforated pipe in place at the resonator's opening.  That done, could the
perforated pipe within the resonator then be extracted?
>
>I gutted many of these mufflers and therefore cut those perforated pipes
where they extend into the muffler; however, The perforated pipes were
welded to baffles within the muffler. The gutting process removes those
baffles with the portion of perforated pipe that extended in the muffler
body.  However, I do not recall what is left holding the perforated pipe in
place on the muffler end of the resonator.  This certainly seems to be an
easy method to pick up the additional diameter to go from 1.5" to 1.75" that
is required with a 2.5" exhaust pipe.  Area of 2.5" pipe is ~ 4.9". Area of
two 1.5" pipes (stock size) is 3.52"; 1.75" pipes is 4.8".

>So, if I use a hole saw to drill out the perforated pipe in the resonator
on the outlet side, will the perforated pipe then pull out of the resonator?
Anyone have a set of GTS mufflers that are cut open for inspection?
>
>This seems to easy - although, I wish I understood the dilemma when I had
the mufflers cut open; then I certainly could have removed the complete
perforated pipe.

pipe with holes in it, and rings at each end, which fit the ID of the chrome
tip.  The only thing you can do is remove and replace the resonator with one
of a larger diameter--or remove it entirely.
