Well, everyone, finally got some news for you. After spending another five
hundred dollars to Aircraft Exhaust, Inc, I received a retrofit muffler
(whatever) for my 912. It sits at a weird angle for some reason, not quite
straight but it seems to do what I wanted. The rum rum vibration is taken
up in the muffler and according to my beautiful wife, sounds deeper and
actually like an aircraft now. I dropped about ten db in the cockpit; is
now very tolerable. It doesnt seem to eat any extra energy from
backpressure and was easy to install. Now, this isnt going to make it
silent as in a tractor style with the muffler in the rear with a long pipe.
I have no cowling to absorb the sound and have the noise of the big blade
but it does definitely help. If I were to order a new exhaust system for a
new 912, I would recommend this set up. I believe it is the T2XQ or similar
at www.aircraftexhaust.net. I had the modification as pictured. I your
pipes are less than two years old, you can get the T2XQ mod but older than
that, you get what is pictured. That so far is the only answer I have for
the foul noise my engine produces. Now, does anyone know EXACTLY what motor
mounts we get when we get the 912 from Kolb factory? I would like to get a
softer mount but have no idea what my are. Is Kolb lurking and alive here?
So far so good. Ted p.s. oh yeah, by the way, this set up is actually
2lbs4oz heavier than the one with the double pipes and sits forward another
eight to ten inches.
