Header

Hey, I am trying to figure the differences between a ceramic coated header and a stainless header, is there any difference besides looks? I would think performance of the header would have little to do with coating.

The ceramic coating might help reduce overall engine bay temperatures and if you're running a short ram intake then it may be benificial. Maybe someone that actually has a ceramic header could give you a better answer

that answer was on point.
Let me also add that ceramic coated headers tend to rust and corrode over time. The protection they give from heat isn't beneficial enough to choose it over Stainless.
Most people buy the ceramic because it's less expensive.
IMHO Stainless is best.

Although i know from experience that you should pick a header carefully depending on where you live. If you are in an area where its cold one day then hot the next (like GA.). you should pick ceramic, cause they have very little chances of cracking from cooling too quick. Stainless steel is known for that fatal flaw, because it doesn't contain the heat as well as ceramic does. I own ceramic and have been on for the past year, and they still look and perform as well as the day i bought them.

headers

I do have a short ram, would a header wrap be beneficial. I am just trying to get all of the info before I decide on one. Ceramic is a lot less reflective so it should keep heat down, but stainless is well stainless.

Header wrap is always a great idea.
I use it, and it works.

Stainless or ceramic, try to find one that yields the most HP, and also suits your budget $$.

header wraps are good, but remember that they can retain moisture when the car is cold, so if your engine bay gets wet frequently, it might not be the best choice.

That's why you get one of those fans pointed at the shcool bus driver and blow it right on the header at all times.

i think on the 5th gen, brand is more important than material (ie. mugen over dc, etc.)

I've heard those header wraps can cause cracks to form, but honestly I don't know.

Yes they do. But i've only seen it happen on a ceramic header. It adds excessive stress to the welds of the manifold and greatly reduces performance [B]in the long run.[B] Early on its great. Not to mention if it gets wet thats another can of worms you don't want to have to deal. In my best opinion go ceramic without the header or go stainless steel with a header wrap and cold air intake system so you dont have anyway of sucking in hot air.

Brand? If the welds are clean, collecter size is the same, and material is the same, whay does brand matter? I here everyone grab assing the mugen header. Frankly, there are a lot better power adders out there for the money. I am not planning on dropping $899 right now.

I agree, I heard everyone perfers mugen over dc. But the price you pay depending where you go, you can get a custom header for your car.

never heard of that before. Thats one of the reasons we recommend getting the mild steel headers coated. To keep the header from rusting. I've had my mild steel ceramic RMF for almost 3 years now IIRC and i have never had anyone say their ceramic coated header was rusting.

but stainless puts a nice smile on your face when you look at all its beauty.

I wouldn't expect an RMF header to rust, top of the line custom stuff. I was refering to mass produced headers which most people on here purchase. I've seen a few brands rust w/ my own eyes.

I'm kinda scared to drive my car this winter, don't want that header to break.

As sexy as stainless headers look, if your worried about heat why not just retrofit the OEM heat sheild. They don't look too bad when coated in matte black or polished.

Header coatings are not only used to prevent rust and make a nicer looking product, but we all know they also help reduce underhood temps. The single biggest difference between a coated, (insulated one), vs an un-coated, (non-insulated one), is the effect on the combustion chamber temp. "Insulated" tends to raise the temp. while "Non-insulated" tends to lower the chamber temp.

It becomes a matter of preference based on whether you're "NA" or are running a power adder. In the case where a turbo or supercharger is used, equal length, large diameter SS tubes are typically used by their manufacturers to help disipate and lower combustion chamber temperature. Motors that are NA respond reasonably to the addition of either type of header, (SS or Ceramic), producing marginally better TQ / HP numbers.

If air intake charge temperature is your ultimate concern, opt for the cold air intake instead of the short ram style. That way you can use either style header and it won't adversely affect your intake charge temp.

Unfortunately, the only way to determine for real which combination makes the best performance numbers, you'd have to run them on a dyno and see for yourself.

All applications are different. Then you have to start looking at fuel delivery and timing curves, (ECU programming), to achieve the best results from the addition of the header and air intake.

I've heard heat wrap is somewhat bad, because heated air moves alot quicker in the exhaust which is good. And with heat wrap it cools the air making it slower. This is only something I've heard. Also I had a ceramic coated header in my previous lude and the engine was cooler than with my stock header without a heat shield in my new lude. Anyway just my 2 cent

so with this being said couldn't you just let your car warm up for say 5-10 min before running it and then park it in a place that is out of the wind and elements and let it slowly cool down like normal cars do... or is time from shutting off the car to the time it goes to a outside temperature cold to short of a time to where it will crack??

See i live in Ohio and i am looking at getting stainless steals but (for example) Saturday it was 50 degrees and today Monday it is snowing and slightly sticking...

i would like stainless for the look and the anti rust ability but i don't want them to crack cause stainless is hard as hell to weld!!!

Re: Header

But who really lets their cars warm up 10 minutes every time before they drive it? That's wasting gas.

Like I said in your thread, stock header FTW. If you want something that looks good, look at edge2lyfe's MR page. He got the header cover polished and the whole bay looks flawless, and brand new from the factory. He also got the radiator supports and battery tie polished. It's really clean.

Re: Header

um its common sense to let your car warm up for 10 min when its 10 degrees outside for 3 months straight.

and that engine does look sweet but i think im gonna go with the headers...

i dont drive mine until it reaches a certain oil pressure during warmup. Usually takes a few minutes

No ****. I went ceramic and in 2 years is works fine but it starting to look bad...

I am seriously considering going to a hytech replica when I replace... thoughts?


and...

I let my car warm up a lot (while driving) and then I let my happy ass do whatever I feel like... (I'm talking 2.5k rpm max for at least 5 minutes, or when the temp bar gets to its plateau)... I live in the middle of nowhere so I am more patient than city folk who do lots of short trips...

and...

blake is right, stainless is sexy.

Heat wraps keep your exhaust hotter... thermal dynamics isn't hard, trust me.

Re: Header

My ceramic seemed to get little rust spots but I guess it doesn't seem to be getting bad fast... I know I didn't get any gains from it though... the header just seems to be the weak spot in most mild builds... I think it held me back the most.

anyone have advice on the the hytec replicas?? Will my Koyo 2 row radiator be able to take this header (I think it will... from the pics...)??

Official HyTech replica H22 Tri-Y header Group Buy!! - Preludepower.com
New H22 Tri-Y Header Tested w/ Dynos!!! - Honda-Tech

300ish for actual gains... I like it...
