MAC makes a good header, but their coating is shit. You'll see your headers start to rust within the year.

Correct me if I am wrong, but I thought the reason the BBK's were a bit pricey was due to stainless construction. The headers on my mom's Cobra still looked pretty new 3-4 years down the road when she traded it in on the '03. I don't know if they were stainless or just had a top-notch coating, but they looked way better than any MAC header I've seen of the same vintage.
