My new coax muffler.

Brian

Looks like the holes in the inner pipe need to be larger
towards the aft end.

Paul Lamar

The holes are all 5/16", I put a rod into each one and pulled it back, so each hole is like the holes in a cheese grater. Each one protrudes on the inside of the pipe and should scoop air out of the inner pipe and also provides some turbulence inside the inner pipe. We whould see in about a week how this muffler works.
