Thread: Series 2a 2 1/4 petrol exhaust pipe diameter

Hi guys,

Could someone please advise both inside and outside diameters of series 2a petrol, exhaust pipe, I'm considering using 2 inch glv. Conduit.

Thanks

Norm.

38.68 OD

33.61 ID

That was at the tailpipe. I'll double check the rest in a sec.


EDIT -

Main pipe is around 43.68 OD
So, ID is likely around 38.61, but that is just a guess.
