I will be really grateful if anyone can help source this bolt
It is the ? welded on bolt that forms the 3 bolted end of the catalytic convertor that attaches to the manifold end.
One has fractured during refitting a cat and while a regular bolt can be used I would love to source the ?splined domed head bolt put in by Porsche when the make up the cats.
Any info greatly appreciated, you are THE guys...

I know what bolt you are talking about. Unfortunately it's not listed as a separate part number in the PET it's show as included when you buy the whole catalytic converter.

Yes , they are press fitted into the cat flange at the factory but somebody has to make them for Porsche so I would love to source them. I know that a standard 35mm M8 hex head bolt will do the same job but the OCD in me would like all the bolts to match ( no I'm not knocking out all the remaining 5 others to match the single hex head !)
Sorry I don't have a pic handy as my car is in the bodyshop right now.
Again all info very gratefully received
Mike

I had a couple of those break on a previous car. The dealer couldn't get the press in bolts so I just used a standard bolt. The only time you'll see it is at an oil change.
