Regarding the use of titanium for our rotary exhausts.....Here is  
what Burns Stainless has to say about it. "Titanium compared to 
aluminum is 60% heavier and twice as strong". "Titanium is not 
recommended for high temperature applications  ie 1600 degree 
sustained like high pressure turbocharger or rotary engine exhaust".
       They do, however recommend the inconel tubing for rotary 
exhausts, and stainless 321 for turbo applications because of 
it's resistance to fatigue at high temperatures.
