I have Jet Hot coating, as it looked like you did too. Did you have everything recoated? Can they spot in an area of damage or do you have to have the entire system recoated?
Come to think of it, the exhaust does pop if you back off at high rpm. I remember thinking at the time it had to be sucking in air, but it slipped my mind later.

I believe the flanges are 3/8". I bought the flange kit from Bill Littleton at
www.gcperf.com/, for about $140. However, I think all of the Backdraft Dealers carry the kits now.
As far as the coated headers, sparks when welding but cleans up nice. Didn't disturb any part except the end of the tubes. Looks good and no problems so far. Well worth the time and money!
