These ducati guys..... I'm 35. My entire career since 18 has been in manufacturing. Before that I took a 2 year course in high school on manufacturing technology, in which I was top of my class both years. After that I entered a 4 year apprenticeship program for tool and die making. I've taken 3 college level metallurgy courses and 2 college level equivalent structural engineering courses. At the company I work for I've worked with every industrial material imaginable including magnesium, carbon fiber and yes, titanium. In the past 17 years I have developed a comprehensive understanding of the strength and abilities of common industrial materials. I'm not just a shade tree mechanic. Pound for pound steel is 5% stronger than titanium, but titanium is 45% lighter than steel, so you can have an exhaust that's just as strong for 40% of the weight...but most ti systems have a .040 wall thickness which is comparable to stock steel systems, so they would be just as strong as the stock steel pipes.
