Bought a set of used MAC shorties for my fox. After 1 season they're full of holes around the collector. I have 2.5 bbk catted midpipe for shorties

I was about to order bbk ceramic but checked some message boards, some say they start to peel and rust after a few months, others said the still look new after years. Anyone have personal experience with bbk chrome or ceramic?

Here's some materials and brands I've found:
-ceramic (bbk around $450)
-409 Stainless steel (Flowtech $500)
-304 Stainless steel (Flowtech $592)
-Pacesetter "Armor" coat $530
-Or another brand/material/coating.

What lasts the longest?
