installing.

The current easy, cheap and quiet solution is to use the
RX-8 Renesis engine with the much tamer exhaust, use the RX-8 exhaust
manifold, weld on a 180 deg. turn and couple it to the Hushpower II
Resonator. Fits under the cowl and I have 130 hr. flying without a
problem.

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,

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

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.
