Like you I have high regard for TTI headers but not their customer service. I bought a set of small block Mopar headers from them years ago, and paid plenty extra for ceramic coating. Less than six months after install the coating was dissolving and looking like crap. I called TTI and got this "yes we are having problems with our ceramic coatings that we subbed out. Send them back and we'll re-do them". Sure, that's real convenient. Down the car, remove the headers, pay for shipping. I asked about getting some money refunded because the send back option sucked. Nope, and they seemed to have no concern that I paid all this money, was a returning customer, and that it was their fault.
