Received my DNA muffler this past week and got it
installed and running. Havent flown it yet, but have done some taxi and full
power runups. So far I'm a little disappointed. It doesnt appear to be any
quieter than my home made muffler. I'll reserve judgement until I actually fly
it, but from the cockpit the noise level seems the same, and my buddy standing
about 50 ' away said he thought the noise level was the same.
One thing not the same - the muffler screwed
up my tuning. It appears to be considerably richer now all across the RPM range.
And the big bog at the staging point that took me so long to tune out is back
with a vengeance. Oddly, in spite of the tune issues it still appears to reach
the same static RPM as previously.
Looks like the solution for me is going to be
the high $ headset and the rest of the world is just going to have to live with
it.
