BBK are junk. Mac are junk.
Now if you can deal with a header leak here, holes not lining up there... than pay a small price for these headers and deal with them or fix them.
You get what you pay for but if you are on a budget, go with the BBK. Mine sometimes seal than sometimes don't. The welds on em are about the worse I've seen (the flange face is something to be less than desired).
For $160, you can't expect a perfect header though...
Kooks does make them for a FOX and they make great power, but they hang REAL LOW.I run Macs, like them.
The best, not sure if they make them for fox's but Kooks makes some of the best headers around. $$$$$ though.
BBKs are good, worse for ground clearance than Mac from what I have seen.

I don't know what hes talking about.... Anyway, I had BBK shorty unequal ceramics, they look brand new after 2 years. They fit perfect, didn't leak. Now i went to BBK Longtube ceramics. Also awesome. I'd buy bbk everytime. And yes, but cermaic.
