I spent the time to cut away the outer shell from the stock manifold, leaving only the inside pieces. Then I welded the two pieces together. None of my pictures show it very well, so I'll have to take a new one if you need it.

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 erve_W0QQitemZ230338894473QQcmdZViewItemQQimsxZ20090423?IMSfp=TL09042314 10006r30271 Bobby Hughes -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Christopher Owens Sent: Saturday, April 25, 2009 12:32 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Exhaust system wall thickness 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 On Apr 25, 2009, at 12:49 AM, Al Gietzen wrote: > with, and I found some notes about using SS handrail tubing, > approximately 0.12" in wall thickness.
