What kind of Header is this?

So when I bought my 426f from the PO, I received an entire box of spare parts and in there was this header. I have no idea who makes this or if it is even made/compatible for the 426. It is larger than OEM and made of Titanium, anybody know anything about this Header?

Probably a YZ OEM header

I don't think so. Doesn't the YZ OEM have a heat shield? And I don't think the YZ OEM is titanium either.

Most YZ headers are Titanium, and some year WR's too.

But yours has an aluminum flange, with is not stock

Probably old FMF.

It looks somewhat like the tapered White Bros.header I have.

I would like to use it, just is this something recommended for the 426f? I have looked at a few aftermarket headers and the FMF has a exhaust chamber versus this straight through header. Any thoughts?

Ride it with both the stock and that one. Then decide for yourself.

I am hoping it will fit into a FMF Q4 muffler. If it does, I am going to have it ceramic coated inside and out to keep the heat down and away from the rubber radiator coolant hoses. The front bend is a good 3/4's of an inch closer than stock to the motor and hoses.
