Yah I ran BBK ceramic shoerties for 3 years, and they never turned blue.
Well man does the car have a new sound...WOW. This thing sounds about the same at idle, but when I give it some gas OMG..its like unleashing the beast..lol. The shorties didn't scream so..man this mofo sounds plain sick!! It is def. night/day difference!
Install wasn't to bad either, and man do those 1 3/4 tubes look sexy in their! As for the coating I started it and ran it for about 5 min..then went to re-tighten bolts..headers were so hot i couldn't touch-um (right after shut-down)....after about 1-2 min. I was able to grab them, heh, this stuff is awesome!
