I am replacing the SS Hooker hedders , they have pancaked tubes , a few cracked . Is this ceramic coating on the Hedman hedders going to look as good as the SS after a few months/years ? Or does the coating peel off after a few months or years ?

Sure looks good now , hard to tell the difference between SS and ceramic coating .

Thanks
 
I have the ceramic coating on my Doug's headers......a couple years now.

So far so good.
 
The coating is as durable and long lasting as the warranty. There are companies out there that offer lifetime warranties.
 
Should last for a longtime but read the instructions, especially the part of not putting them on a fresh motor. Fresh motors run hotter and the coating will come off, my buddy wishes he would of read that part. He had to pull them back off and drop a couple hundred bucks on those brand new headers and sent them to jet hot. They have been fine since.

Thanks , that's good info , did not see that in the instructions included with hedders . Don't think I should worry the motor has about 1,000 miles on it so it's not fresh .
 
Another thing ceramic coaters generally don't tell you is to be sure to use stainless hardware not only on your headers but on your valve covers above them ... any resulting drippy rust will NOT be covered by your warranty.

A good high temp ceramic coating job should last for many years. Some places do not coat the insides of the tubes though so make sure you know who you're dealing with and getting exactly what you want.

Presuming the next question, I got out of the high temp ceramics a couple years ago, sorry. The shipping costs were just too prohibitive for my customers.
 
Thanks for the great tip about the stainless hardware, Leanna!

The reason the header mfgs. say not to use on a fresh engine is usually "do not use to break in a new engine". This is because new flat-tappet cammed engines need to run at 2500 rpm for 20 minutes to safely break-in the new cam. If you're running a little lean on your fuel mixture your engine will create too much exhaust heat and discolor the ceramic finish.
Roller cams do not require such a break-in.
Best to run any break-in period with a slightly rich fuel mix.
