For someone who has an engineering degree, I feel thrilled when I hear terms like creative, and elegant engineering. These days, we only hear about cost reduction engineering. Best achievements in engineering always come when creativity is at work. Kudos, and please keep us posted.

Suppose I should get titanium for about the same price....

Given the temperature at which stainless steel oxidizes vs. the lower point for titanium, I would "bite the bullet" and buy a new set of the Porsche nuts. Indeed, though not overly expensive when compared to the very high end (i.e., $25,000 or more), given that the Dundon exhaust is not inexpensive either, the nuts should be the least of the issue.

Re elegance in engineering, a great automotive engineer, John Barnard, taught me that, in most instances, the best engineering solutions are the most elegant ones. I also learned that it is usually most cost efficient to go for the highest level solution and scale down rather than start low and scale up.

Learning from the master, what an artist he was with F1 cars. The 640/641 were some of my favorite F1 cars of all time.

Love this thread.

When the team of creators, engineers, machinists and carbon fiber experts is highly skilled and works well together, the results are good.
