Headers, TTI or Doug’s?

TTI installed around 2009. Overall I really like them despite they started rusting around 2-3 years of garage kept car. I had to shim motor mounts and slot K-Frame to push engine/trans back some. Once I got engine positioned correctly then good clearance and NO dents were needed. Keep in mind Mopar K-Frames were super sloppy production tolerances were all over the place. But TTI provides the engine location specs in their instructions. Oh and no leaks either.
Do yours have the ceramic coating?
