high quality...maybe not high. lol. i bought the cheap ones which were just painted. and after install i had quite a few spots that were scratched thru and what not. Also had to take my grinding wheel to the flange that mounts to the head, to make it all flat. It's all no big deal, and still makes the headers totally worth it. just something everything should know. I would still buy another set of flowtechs tho.
