BBKceramic vs nickel coatins worth it?

[Chevyguy]

I know for looks you can't beat the ceramic coated ones.

These are going in my daily driver, my stock headers have warped flanges with stripped out threads, the H pipe has no flanges left and we used a pair of "handcuffs" and some crappy bolts, I'ts held ok for 30,000 miles but not too much more.

I figure get the 1 5/8" longtubes since the whole mess has to go, I already have a Mac 2.5" cat back

I'm gonna be driving in the winter in the Northeast so figure plenty of salt spray. I don't care if they get discolored, but dont want them to rot out from the inside, that would bite.

Any tales from the street about the Nickel coatings???
