I had Series 50 Flowmasters on my previous Tiger and experienced the same
affect.  My term for describing the boominess was "waffling" in that it seemed
to be a pulsing pressure, similar to driving a late model 4 door with only the
rear windows open (if you've ever experienced that!).  My current Tiger has
Dynomax mufflers and I could not be happier with them.  Quiet(ish) when
cruising and plenty loud when under hard acceleration.

If you would like to hear these mufflers go to the following link:

Dyno Day in March 2008.

Thank you to everyone who has (or may) chime in. Just to answer a few

When I said "Boomy" I meant the resonance was so pronounced it was disturbing
to deal with.  Maybe it wasn't the best of terms.

I think in an open Tiger noise is more palatable than in an enclosed car.

On this car (Plymouth Valiant) a single exhaust is easier to snake by the gas
tank.  That is why I chose to use it.

The 3" (7.07 sq.in.) single exhaust is about equivalent to dual 2-1/8" (7.16
sq.in.) pipes. That doesn't seem to be over kill there.

An "H" or "X" pipe is irrelevant in a single exhaust. Within 2 feet of leaving
the exhaust manifolds the are constantly merged.

  Ironically it is only at about 4-5,000 RPM that I notice a minor gain in
performance over the choked down,  single 2" pipe and stock muffler I
originally was running. Ugghhhh, I won't tell of the "days" of labor I spent
putting this together from a bunch of stuff I had lying around.  I really
though with the merged single exhaust and the three chamber 50 series it would
be quieter, but then I have been wrong before.

Thanks again everyone for the input.  We can now return to our drama "Tiger
bidding on Ebay."  :-)
