On a side note: Some of the best car advice I've seen from a Fox "Toober" in recent memory:
If you want ceramic coated headers, buy them uncoated, install them, beat the
out of them until they fit perfect and [then] have them coated.
I mean, that's usually one of those things you just don't learn until you've done it but pricewise, the out-of-the-box solution looks attractive.
