headers questions
i like the idea of coated, keeps temps down and all. i just replaced my o2s last sept or so, will they get trashed bty the coating curing process? weighing all my options - i know i gotta get some extensions and ill have to get an exhaust welded up too.
Ceramic coating will NOT prevent rust. Coating is strictly to keep exhaust temperatures hotter to increase scavenging, while keeping the surface temperature of the header a few degrees cooler. It is more for performance than anything else.
While ceramic coating will delay the formation of rust, it simply can not prevent it. Depending on your climate conditions, driving habits and frequency, they will ultimately rust. After a year with my Jet Hots and moderate driving, they began rusting badly.
If you want rust-proof headers, pick up ceramic coated stainless headers.

Perhaps it has something to do with increased EGTs from car to car from a performance standpoint.
