Many types of 13B exhaust systems and configurations have been discussed
and experimented since we began flying the 13B (and other rotary engines
configurations)

For exemple, Ed Anderson is using two exhaust pipes and two muffllers,
and is apparently well satisfied with this arrangement.

Ed, could you please list the pros and cons of such an exhaust
configuration.

Thank you

Yvon

Ed is not on here Yvon.
Sounds like a good idea to me however.
