Chris,
That thickness was used by Ed Anderson for his head pipes. The muffler coud be half that and be more than thick enough. If you use 321ss both could be thinner as it holds up better when hot.

Subject: [FlyRotary] Exhaust system wall thickness

Hi all, 
 
Looking through the archives today, searching for some additional information regarding materials to build a rotary exhaust system with, and I found some notes about using SS handrail tubing, approximately 0.12" in wall thickness. If one were to build matching muffler components to attach to those tubes, would 0.12" be sufficient thickness (presuming 304SS or similar)? Thicker? Thinner? 
 
Many thanks and best regards, 
Chris
