I'm starting my last challenge.....exhaust.

What size pipes are the best?

The best type of connections or joints?

I've seen and heard about the failed mufflers on 13bs......the ones the burn
that the metal guts out, and the one that plugged up the exhaust with the
packing material (and crashed). Can you recommend a bullet proof muffler
brand for a rotary (Renesis)?

Thanks,

I think you need to get some .049 thick Inconel sheet and make your own. Keep it hollow.
Don't put ANYTHING  in side as it wiil melt and could plug the opening. You can trade
Inconel cost for more weight by building everything out of
.065 thick 304 SS.

Here are some ideas that work. The Russians recommend the 2 by 2 square tube
out of the ports  which you will probably have to fab out of 304 SS or Inconel sheet.
