I am not understanding your logic here. Why do exhaust (specifically midpipes and rear sections) have to be flexible or expand? All you are doing at that point is creating higher chances of exhaust mounts cracking and exhaust leaks. Whether you use Ti or SS it's all the same. Anything after the downpipe doesn't matter. We all know that real exhausts use inconel

That's why T-304 Stainless Steel is one of the best metals out there for exhausts and is RPi exclusively uses this type of metal. Just remember dudes, knowing is half the battle. :P
