Another vote for Gary Cook, he did a great job on my headers and exhaust.
I've been trying to get in for a week and a half. I really like his work too. No one else has called back. The number I got for Diamond doesn't work.
A few years back I tried getting in touch with both of them without any luck for several weeks. As I mentioned, Ernie from MotoFab does work as nice as anyone else and he responds very quickly and gets your stuff taken care of in a timely fashion.......I think both Diamond and Cook do excellent work, but both are like ghosts or Unicorns.......
Just my .02.....grr
