This will be a 2 part question about the rover k in relation to exhaust and MEMS
1) the first lambda probe (before pre-cat) is used for mixture control and the second only for checking the status of the main cat ?
If so, will the system work without the second probe or not ? Since I have packaging difficulty with the cat and thinking of not using it.
2) I would think that the pre-cat and the cat itself are substantial resistors to flow, draining most of the energy out of the gas? Because the pipe
and backbox I got are 72mm diameter while most of the OEM exhaustsystem was 44,5mm. Otherwise the step change would cause a negative pressure wave to
propagate back towards the head... and since I have no data on valve timing (overlap) I have no idea what the impact of this negative pressure would
be.
Thanks

Don't know about the cat though
It's fine to run just the 1st lambda probe with the MEMS ECUs. This is exactly what I have on my Caterham (MEMS3).
I'm not even going to attempt to answer (2) as it will just end up in an internet argument.
