i don't know if it is BETTER at keeping temps down or not (but i bet it is); it is excellent stuff, they coat both inside and out, looks awesome, and has a lifetime warranty
Yeh i got the BBK chrome shorties. Burned off in a week. Now they are crappy and rusted. I wish i would have gotten ceramics. Next on my list is BBk Ceramic Long tubes.
I got the headers yesterday afternoon and then threw them in last night. The whole process took about two and a half hours. They went in really easy except for that stupid EGR tube Everything else bolted up well with no leaks. The ceramic finish is real nice and the overall quality of the header was good.
I was very impressed with the performance gains. I didn't get any additional top end power but the low end torque increased significantly. Definately a nice upgrade.
