Found a good place with good price for ceramic coating for headers
 

I'm going to go directly to this place when I get my headers to get them coated.

Price range is Just right, and it's local (belmont)

around 180 - 240 depending on length and dimension.
They said that the typical 4 cylinder headers are around 180 to 200. 10 day turn-around, but I found on some m3 forums that they are really good what what they do!.

accessories plus is the name of the place:

Just putting this out there since I wanted a place local to do powercoating.
