ceramic vs stainless headers

I posted a thread about magnaflow exhaust and about after a week or so in the discussion of that thread I needed help with my headers. I just felt like that thread topic was answered and lost interest so I decided to start this one about headers. I have been reading for days about headers. Stainless vs ceramic coated. I dont mind spending extra coin on something that will look good and last for years to come. I cannot find many reviews on the hedman stainless steel hedders #62190 which are uncoated and made of 304 steel. I think I want those but I need to be schooled here on the pros and cons. I just dont feel comfortable buying something because i dont know enough about them. I read a post that the uncoated stainless will turn a bronze color after awhile but will look better then the ceramic coatings once they start to rust and fail. I cannot find any pics of this to see what they will look like. I also read about the uncoated stainless let off more heat than ceramic. Not sure if that is important or not. Than I was reading that stainless steel with ceramic coating is the way to go, which kind of confuses me because what is the point of stainless with ceramic on it if the ceramic turns crappy looking and fails. So which one do I want? I would like to stick with the hedmans because everyone says the 68198 are a perfect fit and the hedman 62190 is the same thing just stainless steel. Im running a 454 with oem cast iron heads in a 66 chevelle. Can someone please help me out here? Im looking to learn a thing or 2 and make the correct choice!

Re: ceramic vs stainless headers

My friend only uses stainless Hedmans and i'm getting the 62190 for my '67. I already have the flowmaster stainless exhaust.

Re: ceramic vs stainless headers

If you want to see raw stainless steel headers Google "Pro Stock headers", then search images. They all use uncoated stainless headers.

Re: ceramic vs stainless headers

Stainless will discolor (blue or gold depending on the temps), but they will not rust. There will be substantial more radiant heat compared to coated. Anywhere the coating is scratched will rust and the inside of the pipe will rust of course. For a daily driver I would choose the coated header and be mindful of nicks and scratches. Stainless set shown below...

Re: ceramic vs stainless headers

Here is where the disconnect happens... Ceramic coating is an INSULATION. Its sole purpose is to retain the heat within the exhaust system... resulting in lower under hood temps, which can lead to improved performance. The fact that it is shiny, is an added benefit. It was not developed for its eye appeal, it was for its insulating properties.
There is also a black ceramic coating that insulates better than the shiny, and retains a near new finish for a very long time.
Stainless simply resists rust & corrosion. (looks nicer, lasts longer than steel) but, does nothing to control heat issues.

Choose accordingly....

nothing stays new if it is used.

My good judgement is the result of my experience... although my experience is the result of my bad decisions !!!

Anylizer....... do the positive effects of ceramic insulation greatly outweigh the looks of plain stainless? I'm just cruising to shows, I'm not to concerned with gaining HP or anything

Based on your input,I would guess that you would be happier with Stainless, un-coated headers. They will turn blue & bronze, which can be polished off if you so desire. Although it will return when heated up again.
The shiny finish of the ceramic will deteriorate over time, and in some cases discolor at the heads almost immediately.

For what it's worth, I am a coating applicator, have been for 18 yrs. I will be using the black ceramic on my Chevelle. If i wanted the "bling" factor... I would use straight stainless. it just wears better. IMO/IME

Kirk those look pretty nice especially after all those years!
Anylizer... thanks for the info.

Just one more thing. What is the disadvantage of the stainless higher temperatures in the engine compartment? Will it be a concern of mine?

Just cruising, stick with iron, get them coated.

The way our cars are set up is the heat from uncoated stainless headers really a factor? I can't believe I'm making a skeptical out of this.... I rebuilt the entire car from the ground up and now I'm stuck on headers and can't make a decision. I feel like a idiot. I however really appreciate all the knowledge from everyone here!

Re: ceramic vs stainless headers

How about something else to confuse the issue After years of dealing with headers scraping on speed bumps, driveway aprons and debris on the road I gave up on long tube headers. I do not need every last horsepower available for my cruiser so this build has mid length ceamic coated headers. Even with 3" exhaust and a lowered car there will be no clearance issues.

Re: ceramic vs stainless headers

Your plug wires/boots as well as the starter will thank you for choosing the coated versions.

Re: ceramic vs stainless headers

The perks of ceramic coating are of the many. As mentioned prior, the Cerakote Glacier Series Black has by far the best heat properties that will be much much better than any kind of wrap. Glad to see that wrap is out of the picture anyway. Stainless steel, as shown in the image by another fella, with for sure blue and look very wonky. The perks of ceramic coating are far beyond any type of paint or bare metal, and in some cases can look AS GOOD AS a chrome header without the blue.



The coating itself is only as strong as the prep process from the factory. Your best bet might be to get a stainless set and swing on by your local Ceramic Coating Business to have them properly coated. I've seen many of many of many of many high dollar powder coat and ceramic coat jobs that come off like nothing is there. Which ever weakness you've heard could very easily be avoided if maintained correctly. Proper Tune being the most important.
