2) possible to switch secondary downpipes only?
3) different downpipes on LCI / pre LCI or is the connections the exact same?
4) can I fit a stock exhaust from an -18 without OPF on this car?

This is for an EU spec car only
1 - yes, but you need an OPF DELETER kit, which still throws CELs from time to time
2 - yes, because it doesn't have a sensor, but most probably the OPF sensor will detect it, since it's after the 2nd dp
3 - they are different

4 - the downpipes are different and specifically in this case the 2nd. So you would need modify it because it ends with a flange and not a clamp.
