Yes they do

Hate to rain on your parade, but QC has never coated the inside of headers nor do most other shops. If you ask the right questions you'll get the right answer. Bill will tell you that they only spray inside the collector and primary area as far as you can see.

This is NOT ID coating. Even if it were done throughout with Bright Ceramic, in most situations Bright Ceramic would not stick to the inner primaries because it can't be prepped sufficiently. ID coatings are done with a different thermal barrier that is capable of bonding to less than ideal part prep.
