Yeah, that sounds familiar. If I recall correctly, my manifolds and crossover pipe (connected the manifolds on the V6, fyi) weren't coated inside. I'll see what old pictures I can dig up for any sort of confirmation.
*edit* Found exactly what I needed...and it seems my memory sucks. Manifolds and xover did have coating inside. Never had any issues from it, though.
This is when new.
...and to show durability, here's a shot of the front manifold about four years later when some of the underhood piping got redone.
Replacement pipe and blue downpipe were done locally after Jet Hot screwed up thrice.
Everything from the downpipe back was coated inside (sterling finish that you noted). Didn't have any housings coated.
The Sterling held up really well on the post-turbo bits aside from scratching due to install/teardown & general hands-on stuff done in the garage.
I'll check with my buddy to see what we used on the housings...
