Greetings all and happy new year,


What are the disadvantages of straight pipes out of the engine without
muffler for a Renesis engine--??
I understand that the exhaust noise is less than prior rotaries.

This will be for a cozy so the noise will be in back of me.

I have never heard an RX8 engine straight pipe. It might be OK at
a non noise sensitive airport.

I haven't heard one with a fish tail end pipe... but the bridgeported 12A
gyroplane without the muffler was an intolerable screaming banshee...
everyone in the county behind the tailpipe knew I was making horsepower!!
My Lightspeed ANR headsets weren't enough to calm the beasty in flight... of
course, I was 6' in front of the tailpipe without any type of enclosure
though!!  My panel label on the throttle read, "Volume" !!!

I loved that banshee!!
