Where do you guys get the headers that have some type of silver coating? Do you just buy the headers then have them coated locally? I can't seem to find them on Speedway or Performance Bodies for sale like this.

thanks.

The headers we run on our DW came from JR Motorsports. In there catalog they have them listed as coated or uncoated. Other manufacturers might or might not do that.

FYI: We have tried them coated from the factory and sending them to be coated ourselves and while the coating doesnt come off they dont seem to hold there color that well on a dirt car. With all the mud, oil, etc that gets thrown on them they dull and even get sort of a stained appearance. The next set I am thinking about having Jet Hot coat with their flat black coating.

I go to Wal-Mart and buy the flat black outdoor grill paint. It's cheap and doesn't burn off right away. Quick to touch up also.

Painting is ok but the coating keeps heat inside the pipe and helps produce more power.

Ego,

Do you buy factory coated headers or go with another alternative?

What type of headers have you had the most luck with? Where can I get them?

On an open collector type exhaust the gains are minimal. I have had a few sets of jet hot coated headers and to me it wasn't worth the extra weight (about 30% extra IIRC), and they were a pita to keep clean. They were sure nice when doing plug checks though.

The ones I had I ordered from Dynatech and they shipped them directly to JetHot to be coated, took about 3 weeks total. Total cost was ~$500 but that was 6-7 years ago.

I had my stock car headers ceramic coated, for the hp, and rust prevention.

I bought them first and installed them, so I could dent them to allow the bolts to fit in easyier, and also a few dents for plug clearance made them better fitting. I also welded turn downs on them.

the coating looked good new, but the mud and oil baked right on and now they dont look like my 550 dollar headers...
I used dynatach headers.

I dont think your going to gain any hp on short open dump mod headers.

I have got our headers coated from a place in AR. It is a ceramic coating and is easy to clean. Holds up well also. I'm on my 3rd season same headers. I think it cost about 250-300. These were mod headers. The coating does not let the header metal heat up like none coated ones do. This gives you more HP and cooler under the hood temps. The headers are cold to the touch very soon after racing. Powder coating will last a season maybe, depends on how much stuff hits them. If you need headers let me know I can try and get you a #. ltr

Headers should be ceramic coated not powder coated. The powder coating is not heat proof and will melt off onto the floor when they get hot.Powder coating is basically a plastic coating that is applied as a powder and melted into a finish in an oven.It is not heat proof.
