Mark,
Inconel is terrific stuff and expensive and light,
but it doesn't last long, ask the racing crowd. The heat cycling kills
it.
Stick to SS.

I agree on using Inconel... that's what I'm using for my new tangential
muffler. Although my first exhaust manifold, which I'm still
running, was made from commercial SS hand rail material and is holding up
fine. It is heavy, but lighter than using the stock cast iron
manifold. Ed Anderson is using these same SS handrails on his a/c and
has lots of hours on them. The secret is in the thickness
(.140").

Kelly,
You just need to fly at Mach 1 so you stay ahead of the sound.
;-)
Can anyone report on the effectiveness of the tangential muffler in
actual real world situations? (As I recall Al G. is running a
tangential muffler on his Velocity.) I ask because I'm in the
process of building one for my Lancair with the hopes that it will work
better than the DNA muffler that I'm currently running. I think it
will work better at reducing the noise level in the cabin, but at what
cost to power? Hopefully, this will save me the cost of a new Zulu
ANR headset. Comments appreciated.

Hey
gang!
I came
across a rare find this weekend.
Any serious
rotorhead will certainly appreciate this.
Bluelines
from 1973 of the General Motors Wankel Rotary
engine.
I just put
them up on eBay
