I thought Schumachers were bolt in and go?

So basically what happened is the exhaust that was sold to me wasn't modified by accurate but instead an amateur job. If that is the case I think that the only way to fix this is to send it to accurate exhaust and have them do it correct but how would that happen with the high temp ceramic coating? Could they blast some of it off to make the fix and then I would have to recoat the header?

I am not familiar enough with those type coatings to know if they can do it in "spots" or not. I would like to think you can get by without re-coating the whole header, but I don't know for sure.
