I have a header for my 4 cyl. PU.

I bought it used...but, un-installed.

Before I install it, should I coat it. There is a good coating place in town.

Is it really worth it?

Would powder coating work?

Powder coating will burn off as it not designed to stand the high temperatures. It needs to be ceramic coated. A good ceramic coating will prevent rust and make your header last longer. It will also help with under hood temperatures.

I put new uncoated headers on my truck with the small block, the black paint burned off in areas and had mild surface rust, but other than that were fine.

Only had them on for under 2 years.

Swapped in big block with the exhaust manifolds that were already on engine, now wanting headers, found some ceramic coated bbc headers for C10 trucks, $269.99.

Most places charge $250.00 to coat headers you already own.

Maybe since it's a 4 cylinder it will be half that.

I plan on ceramic coated if I pull the trigger on headers, to help last longer, look better, maybe perform better, and supposed to keep engine bay cooler.

By the way in Phoenix Arizona area where I live, in summer I doubt it matters, everything is horrible hot!

Worse case is you put that header on, as is, and after a few years it rusts out.

Look on summit racing for their brand, see if they sell summit brand header ceramic coated for your vehicle.

Might be cheaper that way vs sending off, then sell the one you just bought?

These are the headers I want to buy.

You know, I think the main reason I want them coated is to look good.

By the way, the headers that were on the truck when I bought it, the collector flange came off, it had rust.

Maybe if it was coated it would not have done that?
