2inch inlet, straight flow....
since your engine is a high-rev M42, a higher flow less restrictive exhaust will be better

Good exhaust system = Flow good at both Volume & Velocity.
2.3inlet will have too much volume, but not enough velocity.

my backbox and centrebox hav 2.5" inlet but the pipe from the centre box to the backbox is 2.2"...
There are some in the M42club running 2.5" from extractor all the way thru...
