Mystery Headers - Supersprint non-Stepped?

[Titaniu//M]

Hi all,

Can anyone identify what these headers are? I studied them for a while and think they could be early Supersprint non-stepped headers, based on the EGT bung placement and the way the pipe necks down to mate up to the section 1. No engraved markings to be seen anywhere.

Thanks!

There’s a number of eBay sellers that copied the SS non stepped design... so might be that.

Most likely a copy if you can't find an engraving. Supersprint used to weld a plate onto the headers with 'Supersprint' engraved on it before they went to laser-engraving directly onto the tube. The latter method produces a pretty shallow engraving, so it may be possible that dirt/debris is obscuring the engraving

Thickness of the flanges might reveal something.

Are you selling them on ebay as euro headers?

No, that is who I was looking to buy them from. They're clearly not Euro headers, was trying to figure out what they were

Got it. Well, I'm glad you posted this because I was about to snatch them up.

I warned the seller that they were not Euro headers, and most likely knockoff Supersprints but I guess they don't value my opinion much. Whoever orders them is in for a surprise when they show up.
