    In addition, the "more to the story on your rust problem that we don't know about" that you refer to as something I'm not telling everyone is that my poly headers were only coated on the outside, unlike their other headers.

    As they stated and I posted, "We have sent a new set of headers to our coaters for ceramic coating and they will be adding a thermal barrier inside for additional protection."

    It appears there was an assumption made in this thread.

    I'm hopeful that TTI will now coat all the poly headers with the thermal barrier on the inside. Sounds like a win win.

    As info the thermal barrier is usually a $50 add on, no brainer if you ask me. I paid the extra scratch for it.

      TTI does not have a thermal barrier as an option for the poly headers. Ceramic only.

      They offer a ceramic coating with a thermal barrier on their big block headers for $185. I don't see an option for ceramic only.

      This is the info on their website. Hopefully they will add the thermal barrier as on option for us poly owners.
