I've got the Flowmaster catalog and the "delta-flow" is simply three angled
pieces of metal welded in series inside the muffler... The hype (or claim) by
the manuf. is improved scavenging and less sound as compared to non-delta flows
(like mine). The metal plates look like this:
/\
/ \
/ \
/ /\ \
/ / \ \
/ / \ \
/ / /\ \ \
/ / / \ \ \
/ / / \ \ \
/ / / \ \ \
I know, I know, ASCII sucks for this kind of stuff and the above looks more
like a mountain or some trees, but each of the /\ is supposed to be a metal
plate if you were looking down on it. Hence the "delta" /\ name...
I bought their cat-back which included the old-style 3 chamber and I am very
pleased with it. It's not too loud nor too soft, just a nice pleasant rumble
from my V8. I didn't want anything too loud so as not to scare off all the
critters when I'm in the woods. As far as performance goes, I dunno. --It
sure sounds more powerful. ;-)

What is the difference between the normal Flowmaster 50 Series 3 Chamber
muffler and the DeltaFlow Flowmaster 50 Series 3 Chamber muffler? I believe
the DeltaFlow Mufflers is just meant to cut out or decrease interior sound
levels, isnt it?
I am beginning the Spring search for a muffler. I do not want a loud
obnoxious muffler nor a 'ricey' sounding muffler. I want a muffler which
will sound similar(nice mellow tone would be nice also!) to my stock muffler
and, just one which will flow alot better. I have really been thinking about
a Gibson also, just because I like the quiet tone they have.
I have 'some' intake mods, such as running an Amsoil 2Stage Hi-Flow air
filter, I removed the air restrictor plate at the grill, and I am running a
dual(3") cold air ducts from the grill; so I figure maybe the 119,500 mile
old stock muffler may not be able to keep up with the added airflow. I will
be getting a 'performance' throttle body of some type also this late
spring/summer.
Thanks for any and all input.
Kyle
