Chris,
If I remember correctly you have a Renesis. If so, the stock manifold
can easily be cut down and used. It's a little heavy but you don't have
to worry about it holding up. I may try a lighter manifold in the
future. But for now it's one less thing to worry about during the first
100 hrs. The stock manifold can be had for under $100 but may take some
looking. It also has a good heat shield that can be partly used. At
least three folks on this list have taken this approach. Here's one on Ebay with no reserve and no bids. http://cgi.ebay.com/ebaymotors/RX8-Exhaust-Manifold-and-O2-sensor-No-Res

Hi Al,
I agree, but don't have much experience with these kinds of metal and
how much they weigh. I suspected that if I asked about the high side,
someone would reply that I didn't need that much and make a good
recommendation. I do greatly appreciate the insight :-)
Best regards,
Chris

Chris;
You're building an airplane. Weight matters. .035 inconel is good.
