I've been trying to convince VAC to come out with a SS header for our engines.
VAC has a stellar reputation and has been around for many years, established in 1984. Yes, they are relatively new in the e90post community, but they are embracing it fully and have shown their support since joining.
Local thread for their updates:
These headers would be engineered to the highest standards and they would NOT be released unless there was a performance gain to be had. That is just the type of organization they are.
They know about the coated steel header that MMW is coming out with, so they're not sure how many more people would be interested in purchasing headers. Of course, they need to spread out engineering costs over a number of headers so they can actually make money (duh, common business sense).
BTW: they're always looking to develop something new if there's a need. Feel free to contact Mike@VAC if you can think of anything. Doesn't mean it will happen, but if there's a need, there's a stronger possibilty.
Who's interested in SS headers?
