Vance---Umpteen years ago, Midas shops had exact replacements for the
two in, two out TR6 muffler. Worth a call?

A question for all of
you out there. Has anyone found a "look alike" TR6 muffler that flows
worth a rip?
I was chasing an exhaust
leak on my new exhaust system, and out of morbid curiosity I looked at
the inlet pipes on my '74 muffler. It's a miracle that the car runs at
all with the stock muffler. There are a handful of tiny perforations in
the sides of the inlet pipes going into the muffler. The end of the
inlet pipe is
completely blocked. I bet there is less than 1 square inch of open area
for each of the inlets, and it is all on the sides of the inlet so that
the gas needs to make a right angle turn through a tiny hole. This is
compared to a cross sectional area of 2.25 square inches PER PIPE on my
'74. The manifold and pipes are all smoothly bent, nice flowing pieces,
but the muffler is garbage.
Holy constipation,
batman! That stock muffler is a LOSER for horsepower. I would like to
keep the stock look, so I was wondering if anyone had a bolt in
replacement that they would recommend. I suppose I could cut one open,
hog out the innards a bit, and weld it shut. Seems like a lot of work.
Another thought was to
go to a custom exhaust shop and have them fabricate something that looks
stock. I thought a 1 inlet / 2 outlet Sonic Turbo or Dynomax muffler,
with some fabricated adapters, could be made to look stock from the rear
of the car (i.e. have a pair of those gorgeous outlet pipes made for the
non-stock muffler).
Anyone out there played
with this issue? Any neat solutions?
Thanks,
Vance
