I goofed in a previous post and said american racing headers. I meant to say the Pypes are a good header, that clones the Kooks style.
I have non coated headers, and while I dont belive there going to fall apart any time soon, there is plenty of rust on it already. My mom went for the ceramic coating and hers still look like new. Both sets are about 2 years old. But that is one of the points where the Kooks shines. They are made with a good quality metal, so even without the coating, they will stay looking good longer then cheaper made non coated headers. But eventualy they will look more used.
The Kooks do out perform the BBK as well. When I got mine, they were considerably cheaper then they are now. The price gap has closed a lot between them.
If I were buying headers right now, I think I personaly would be looking at the pypes from Brenspeed with the catted H pipe.
FWIW, heres what the BBKs look like installed:
