Porsche 930 - Aftermarket exhaust - check valve pipe

[Pau]

Hi,

I've installed a Rarelyl8 aftermarket exhaust on my Porsche 930 and so deleted the cat converter. All fine and good but I dont know what to do with the check valve to catalytic converter pipe?

Can anyone advise what to do with this pipe?

Been trying to reach out to Brian but cant seem to get a hold of m.

I don't think you need it

Hey Paul, sent you a reply a bit ago. That tube is for air injection. It needs to be removed and capped or just cap it. If memory serves the threads are 22Mx150.

Not sure what is left of the air injection system, but ideally you should remove all of it. Pierburg switches, pumps, hoses etc. Its a good afternoon's work

Thanks for the replies. I'm just gonna cap it off! Thanks!
