Header life
Would ceramic coated headers last much longer than non coated.
I did do a search on this question but couldn't find a response.
Thanks in advance for your input.
The LGs midsection is stainless so it should last a good long time too.
Ceramic coated headers are usually made of mild steel, unless someone has gone to the trouble of having their stainless steel headers coated.
There are more than a few cases of failures after a couple of years and a few thousand miles involving ceramic coated mild steel headers





I should say I have ceramic coated FLP long tubes with 17000 miles on them and they look great.
i would assume that the Stainless Steel headers will probly live longer than you or me.??

unfortunately the pics by AT&NB do not show up. But they did not look good at all.
The headers seemed to have rusted from the inside out near the collectors. There was obvious blistering and failure of the ceramic coating due to the significant rust beneath it.

But how do you know if the set of coated, mild steel headers you get, are "done properly"? ... Especially on the inside? ... If they are mild steel and not done properly then they will rust from the inside out due to the caustic components found in exhaust gases.
If they don't rust/corrode then great. But if they do rust then it can be a big problem what with removal and replacement.
Also, how long can the coating withstand the heat before it starts to break down????
With stainless steel headers, there are no such concerns. Stainless is much more corrosion resistant and requires no coating unless the owner opts to do so for heat reasons.
