David,
The manifolds were done at Rewarder Headers in Camarillo. I used Morse Muffler on Burbank Blvd near the Costco for my exhaust rebuild. They were very competitive as far as price goes. under $400 for my entire system. The coated manifolds cut down on underhood temps alot and they look good too. Where are you located in Burbank? I am on Catalina St. near the Chandler bike path.
