Mark,
I'll be anxiously waiting for your feedback.
With a 3" inlet/outlet and a 4"body I'm not going to be terribly surprised
if it's not too effective thought. Need some room for those gasses to expand and
lose some energy. But if it lives and has some effect it will justify my
ordering one of the race or maybe even the street series muffler.
Has anyone figured out what "special B2 stainless"
is? Sounds like it was created in the marketing dept.

Muffler
Hey Guys,
My new DNA muffler arrived yesterday so I
thought I would post a couple of pictures with some information and first
impressions.
It appears to be very well built, all tig welded, and no
packing to burn out. It weighs just under 5#, which is half of what the
Hushpower II weighs, so if it works, I will have reduced my fwf weight by
5#. To be totally honest, my HPII probably no longer weighs 10# as most
of the innards have long departed the a/c.
The model I purchased
was the Gen II - Collector Series, p/n 1040. It has 3" inlet and 3"
outlet, with a 4" dia. body. Total length is21", body length is
15". Literature says that it is good for 1000 hp, so it may have a
chance of lasting at least 100 hrs on my 3-rotor running for hours at
WOT. We'll have to wait and see on the longevity. I have a decible
meter, so I can take some before and after readings. Cost was $152 with
shipping from Canada.
I'm going out to the airport this morning to see
how well it fits. More on how well it fits & works later...
