Joel, For a stretch of time, I was intimately acquainted with Ford Motor Co converter shells, having been hired as a consultant to help them characterize some problems they had with exhaust and converter components.
I can tell you that the BOTH the internal converter structure and outside metal casing are important to converter life.
Timevalve uses 316 stainless steel for their converter shell. This is a far superior metal for converter application than the 409 stainless steel commonly used in mass-produced American autos. This may account for part of the price difference between Timevalve's product and the $150 replacement.
