So I discussed with the premier powerdercoating and ceramic coating shop in Tampa pros and cons of ceraming coating the inside and outside of the exhaust. They said the outside provided a lot more thermal efficiency than the out. But if I wanted to decrease heat transfer even more efficiently than ceramic coating the interior & exterior, their suggestion was to ceramic coat the exterior twice. Plus it saves time & money, since there's no additional prep time. Just some time to allow the first ceramic coat to cure, and they'd coat it a second time. So that's what I went with. Being that you can't see these pipes when installed (unless on a lift), I opted for the best thermal coating irrespective of appearance. So I went with a "bare" looking black.

Can you send me a price for GESI cat shipped to 30040? Also, not sure if this was answered yet or not. Does the CEL come on with GESI cats in place?

As a suggestion for those that want to do this and don't want to drop the transmission, shop around for a set of OEM take-offs and cut off the secondary cats. So, when the day comes to sell it or return it to stock, you can drop the transmission then. In other words, you only incur the labor cost once. Not twice.
Just a suggestion...
