I’m NA and built a tangential
muffler from 6” inconel. I haven’t run the engine over 3000 RPM –
but so far it isn’t bad at all - and that was inside my garage. I’m
moving the plane to the airport in a few days (took the wings and canard up
there today!) – so I guess I’ll find out what it sounds like at
higher RPM once I get her all put back together.
Thanx

options
I'm thinking that with all this spare
space I could sneak in one of these.
An added advantage is that this would help
form a venturi inside the augmenter.
I know you NA guys have all kinds of
trouble with mufflers, but could the turbo actually help by smoothing out
all the nasty pulses?
