I
was thinking (don't tell my wife she will just find more for me to do)
we are making efforts to find an exhaust/muff. sys. that lasts "a long
time" well like I said , was thinking, about other aircraft I have
owned/flown & the maint. involved with the exhaust sys., none of
them went longer than 200-300 hrs. before work/repairs had to be
performed, sounds like we are already there. I'm using the Hushpower
II, but do not have any helpfull hints have 12 hrs on eng. run so far,
would love to here of someone finding the golden goose here & hope
no one gives up prematurly including myself, just thought I'd throw the
that into the mix to say??? It is -10 deg.F. here in MI, I need to get
dressed & get my butt to the airport & finish the gearleg
fairings, but I will have to go outside to do that, dam. David R

it is heated, EAA builders hanger)

Mark,
Should have read more thoroughly - I
see you listed the part number for what you ordered. My bad. Still
curious about B2?

[FlyRotary] DNA Muffler
Does anyone on the list have any real-life rotary experience
with the DNA Gen II muffler (
http://www.dnamufflers.com/DNA/main_DNA.html)?
It is an interesting design in that it has no packing material to burn
out. Instead, it utilizes ladder-rungs, which they call "internal
sound diffusers", which resemble a chain of DNA down through the center
of the muffler body, which is made of 304 SS. Their web site claims
that the racers use them with great success. From speaking with a
sales rep, they claim there the rotary crowd uses them too. I'm
considering purchasing one of their FULL THROTTLE COLLECTOR mufflers
(P/N 1040), but thought I would check to see if anyone else has used
this style muffler. This muffler has a 3" inlet/outlet with a 4"
body. So it is compact enough to fit inside my cowl. My exhaust
header has a 3" swivel joint, so it should be a good fit.
