Andy,
As an introduction, I'm Director of Engineering COA (in the old days this
was called Product Engineering). We are located in Columbus, IN and Arvin
now ArvinMeritor has been producing exhaust systems for over 85 years.
Definitely the Z06 Corvette was one of the most unique systems we ever
developed and put in production. I personally did not work on this product
but am very familiar with it because of our "Lesson Learned" reviews we have
across our business units. Many of the people that worked on this project
are now retired, but several are still here trying to be the supplier of
choice for the automotive industry. There were several things that "could
not be done" with Titanium that with Timet's (the supplier of the titanium)
help we were able to accomplish, one of those being the Chrome Flashed
titanium tail tips you asked about. One of the reasons this was used was to
please the typical Corvette owner who has a tendency to keep his or her's
vehicle in immaculate condition. The Chrome Flash tip enabled the owner to
"polish and buff" the tip and under operating temperature not change colors.
(Yellow or golden) Another point of record was the mass saving compared to
a normal system of over 40%. You might be interested to know we are still
working with Timet to help them in development of a better titanium that
when the automotive companies ask we will be able to deliver a state of the
art exhaust system again.
Best Regards,
Larry Antle
