A.C.'s comment here about the number of chambers is pretty critical IMO to
determining why some like their flowmasters and some don't....and
unfortunately they all look a lot alike from the outside. 2 chambered are
pretty standard, the 3 chambered are noticably quiter and likewise the single
chamber race muffler is pretty loud. maybe that is why some sound ok and some
find them harsh. I have Stainless Bassani mufflers on my mustang right now but
I've had 2 chambered flowmasters...with 2.25 and thought it sounded pretty
good....but I like loud. Tom - did you say in previous threads if yours are 2
chamber, 3 chamber or one of flowmasters other product lines?

Tom,
I am using the supposedly louder two chamber Flowmasters on my Mustang GT
and love them. I don't have any problems with resonance at any speed while
having a very nice sound at idle and under acceleration. The harder I
accelerate, the better it sounds. This a true dual system with only the
Flowmaster mufflers and tail pipes changed with an increase in diameter from
2.25" to 2.50".
I wonder if the boominess could be due to it being a single pipe system with
a fairly large diameter pipe? I think Owain's suggestion to add a glasspack
in series would probably be the easy and cheap solution whatever the cause.
HTH,
