No, I'm not upset at all. I agree about the materials part being high quality on OEM. I used the OEM stainless manifolds as a basis for my last set of turbo pipes. I also highly doubt that any of these small header companies did ANY research into weld draw, hardness testing, or even annealing though that last would be easy enough with a high temp furnace. They probably do all their product evolution/redesign through analysis of failed returns.

I just felt it was important to point out some of the conditions that the parts we are buying would be subjected to and that I don't think the average buyer is going to wear them out too quickly even with header wrap, though they need to be aware of the problems associated with wrapping mild steel, and most especially for those in the winter areas where salt on teh roads will get tied up into the header wrap and sit there rotting out the pipes under the higher temps.
