Taking Offers - 1990 BMW Factory DTM Inconel Headers, a Super Alloy!

[Shane Snyder]

BMW Factory 1990 DTM 4 into 1 Inconel headers, a piece of BMW motor sport history. Marked 137/54 90, would have been off a 2.7L factory race engine that was raced in 1990. Headers had heat wrap on them, that left some marks on the headers. Asking $3000 obo...

Thanks,
Shane

You should drop them off somewhere and have someone blast them nice and clean real quick.

Here's what they could potentially look like:
Good luck with the sale....nice headers!

Pat,
If mine looked like that, they wouldn't be for sale! What process was used to get them that shiny? Any numbers on your piece?

Thanks,
Shane

Looks like ceramic coating

[m3pat2]

Yes, they are ceramic coated in silver on the outside (similar to JetHot Coating) and the inside is also ceramic coated in a copper color. This keeps the engine bay much cooler and the exhaust gasses flowing faster (not that DTM headers need any more flow =)). I recommend doing this to any header.

Here's a shot on the inside coating. Bump for a very rare header. Also I didn't pay much attention to any numbers on the flanges. It's on the car now, so I'm not able to see anymore.

Pat, where did you get that work done?

Free bump for the DTM headers.

Looks like their site is down for maintenance for now.

My headers looked like the original poster's pics when I bought them. Embee does a great job cleaning and coating them.

I still can't believe how light inconel headers are compared to the stock S14 headers. I recall it was at least a 50% weight reduction if not more.

Pat,

How does the chrome look after running the car?

Mike, first of all I didn't coat the header for looks as a primary reason, but more for reducting radiating heat, secondly it was for preserving the inconel metal.

The silver coating will age to a greyish aluminum color. Darker than the coolant pipe in the picture. Chrome would probably last longer and look better for a show car.

Here's the current look of the coating after being on the car for 3 yrs. and around 9,000 miles.
