Was a mix up and they got done in brite not black like they were supposed to be. I guess it's why you write it down and not do it verbally.

Trying to decide if I want to send them back.

If they cost more to be shiny, only pay for the black lol. They look great, and may have a nice contrast with the engine bay.

I think they looks Good.

I like em, very nice.

Let them go as is... they might screw them up
blasting them

If it don't go chrome it Brad!
They really do look great tho

Mmmmmmm chrome. I like it.

Don't really want to ship them back to Michigan.

Look great. You racing at Norwalk?

I think they will be fine, so nice when everything is brand new

I think they look great.

They look great and I'd use em like they are. I think the black would have been nice, but I wouldn't have it redone at this point.

Hey Brad, Send me the 1 Free Header Coating credit that they give you for their mistake. I need to get mine done. BTW: They look great!

They look good! I agree with Mike. You send them back who knows? I am getting ready to do something on mine also. Will be open
to who does best job and price?

I assume you sent them to QC Coating
and its strange that they would screw
up.. they do all my headers but I live
near by and drop them off and pick them
up... I did take a set back once.. there
was a spot I wasnt happy with and they did
them again
EDIT
My last set on the Rampage I had them do them
in black

Nice headers ! Silver ceremacoat looks nice ! Did you build them ? I just got mine back and they're black.

They look great. The silver should be a little cooler than black, no?

I think they look great. Understand it is not what you wanted too. FWIW we have not had great luck on two set done in black but don't use QC. I see a lot of dragsters with black that turns chalky too eventually. But who knows.

They did you a favor. Shiny is mo better.

They look all wrong!
Tell you what. Send them to me (i'll pay the shipping cost, and order another set!
Nice headers BTW
Not a stock front k correct?
Matt

I used NitroPlate in Nashville Tn for the headers on my Dart, they still look great after seven years.

Wish someone would screw my headers up like that!!

Very nice, Might not be exactly what you wanted but Sweet nun the less! I vote ...run them.

Drivers side, it is a tube k frame with coil overs. I guess I will run them and see how they hold up, maybe do them black next time motor is out for a freshen up.

Those look great on both visual and power potential..............

My shiny headers from QC still look like new minus a few scuffs I inflicted. They are on year 4.

Just worried about my nitrous habbit and what it does to coatings. I had QC's black on my last set hold up, just a bent mess now, so I assume these will be no different.

How much hotter is the cyl when you spray... cant
be that much hotter so they should hold up fine..
we tested a set of headers a group had coated and
went up to 1500*.. they didnt normally run that high
but it was on the dyno.... I built them then they
wanted to get them coated... no issues

Black or silver............a clean nitrous tune WILL discolor them at the first bend and make them dingy right there. It's GONNA happen, don't care who coats them, or what color they are

Monte... whats the EGT on a good tune

Really nice, but show us what they look like with about 50 passes on them. Mine didn't hold up. Went to ceramic black. Held up better, but still got a little chalky around the first bends off the ports.

You can't tune a gas motor by EGT numbers. It's just a number. I only use them to see if all the holes are lit. I have cars that run anywhere from 1200-1600 and everywhere in between.

As to coating holding up on a nitrous car, depends on who coats them. Before we went to stainless headers, Nitro-plate did ours and they held up VERY well. The bends would get dingy in one pass, but overall it held up well. Kind of like a piston coating on a nitrous car. There isn't one made I can't burn off, except for hard anodizing.......LOL!!!

Not to hijack your thread Brad, Monte what do you mean you can't tune a gas engine by EGT numbers? I thought wideband was the way to go? I hope I didn't drop all this cash to monitor something that is pointless.

Please clarify what you mean. Thanks.

And what is this black stuff? Or we talking some sort of coating that they are doing in chrome now? Trying to visualize this.

Is it ceramachrome? If so you can have black done over the top.Also coated on 5 he inside or just spray where you can see?

So will a blown application. Pic = ceramic coated in black. As for EGT's, I can tell you from experience that at 2000*, your rug catches on fire.

This is the black coating

I built my headers out of 16 g 321 ss. Really needed no coating. Someone sold me on the idea of keeping under hood temps lower with the cer black. Said it was good for 2000 degrees.
First time on the trans brake cooked the finish. After that, anywhere you touched them, the coating would come off like dust.
My single egt probe would get to approx 1700 on the brake.

Wideband sensors measure o2 in the tailpipe, not exhaust gas temp. You want to tune an engine based on o2/air fuel ratio, not egt.

The only major exceptions to this are diesels and airplane engines, that are not tuned to a/f ratio.

I use the EGTs to balance intake manifolds...
try to get all the EGTs the same or close with
grinding on the runners in the manifold... most
of the headers I build I put bungs in them at
exactly 1" from the flange... you can see them here

Agree with MOnte on a gas motor the EGT means pretty much nothing other than the hole is lit. The numbers can vary way to much due to many things, Fuel type, timing etc

Some of those black headers shown have been my experience. They tend to get chalky and don't last but maybe just whose doing it. We have gone to a new deal that is basically a piston coating on the headers. So far seems to be working very well.

Who is doing that coating Al? What color does it come in?

Have them done here locally. We have done three sets now and all look great so far. Our dragster has the most time on it so far. A couple years worth right now. Will get a pic up here of the color. They have a few different shades, one looks a lot like stainless after its been run in for a bit.

I'm not saying tune your engine by the EGTs... I was asking
on a good nos tune up.. what kind of temps would be expected
and EGTs would be the only place to get a temp from

Found this one not the best but you can see the color. And yes those are EGT's, to make sure the holes are firing

Here is one of the dragster headers. People seem to like it for some reason. Keep asking what it was and where we got it done. Holding up well no makes chalking etc Did it chase we like to be different.



Here is another of the Stratus. Will be over at the coater to drop off more stuff. Will try and take a pic of the other options he has.

Definitely cool looking. I have to remember that when I want them redone.

Do you have wideband on all 8 cylinders Al?

Those look nice, I'm not a fan of bling so I like that matte look. I prefer matte black though.

Brad, They def did a nice job on screwing up though ha ha

Seems all the company's I am dealing with are screwing up.

Yes we use O2's on each primary tube.

Trust me I feel your pain. Seems these days the struggle is very real. Been working on mine for two years and a lot of that is waiting on parts to be made or having to tweak them when they are.

My Friends and I like shiny.

I don't have any friends
