i got Thorley on my truck, see pics in sig, not too good of pics, but they got a good shiny chrome coating. The flange is also really thick too avoid warping. Only prob is on mine, (may be diff for blazers) the passenger side header doesnt come down and go level (dont really know how to say it) it kinda points down, i guess its in case u want to run the y pipe and turn the exhaust back in front of the t-case. dont know. But they are pretty good. The coating isnt the HIGHEST quality (u can see like a drip or 2 in it) and the welds havent been ground off really smooth, but they are pretty heavy duty.
