TTI Rust

No time to call today so I sent an email with a few questions, including:

To ceramic coat the Poly headers it's an additional $60. For # TTi 383440-134C4 it's an additional $185 and it's listed differently as ceramic with a thermal barrier. Is this a better coating than what is applied to the Poly headers?

I would guess that it depends on if there is a difference in preppwork and such if the quality gets better, its two different options so to speak,just coated is for looks and if done right durability, thermal barrier also traps heat inside the tubes wich adds performance(if its worth it is a different question) and should help the steel in the tubes get less abused by the heatcykles it also helps everything in the enginecompartment that dont like heat by not releasing as much heat.

Reason for less options on the Poly headers might just be that TTI may already have a batch of those headers with just standard coating and wants to sell those before they make another batch with possibly more options if at all,i suspect the polyheaders being a kind of slowmower compared to the abody stepheaders that must move quite well.
