John, no doubt a sturdy exhaust. However, it
may not provide you will maximum power. When I read early-on that the
rotary engine needed minimum back-pressure for performance, I also though that a
large diameter tube would provide minimum back-pressure. It turns out that
is not the case. It has more to do with reflected waves and length of your
header pipes. Smaller pipes keeps the exhaust velocity up and the
reflected waves can help scavenge the chamber at certain rpm depending primarily
on the length of the header.
1 3/4 - 1 7/8" dia tubes are frequently mentioned. I
use 2" diameter which may be a bit on the large size. I wouldn't hesitate
to fly with your set up, but I think you may be looking for additional power
later.

Enclosed is a picture of the 2 1/2" stainless
exhaust hooked to stock turbo manifold. Heavy, but bullet proof.
