Anyone with direct experience know what the ID / OD of the RM Avanti Clubman stub/manifold is?
I'm currently on a v4 BGM - which I think is restricting the topend on my RT but like the advantage of the 4 stud fixing and wondered if you could keep the stub and change the pipe.

Have you considered welding on one of
these to your pipe of choice?

I’ve just tried a brand new BGM TS1 stub and its a nice snug fit on the avanti Exbox header. Both measure 41.5mm OD. You would have to chop 10mm of the actual length of the BGM stub for it fit as per the Exbox stub. Pm me an email address if you want me to send pics
Update* tried 2 BGM stubs for TS1. One fits as above, the other is 41.7mm and doesn’t fit (but could be made to) and the stub is actually 3mm shorter than the other BGM stub.
