Clio Cup query

The 197/200 have dual exhausts, I think as you say the R3 might just be a single as i've seen a few pics of what I presume is the R3 and they have a single.

All the clio cup racers have dual exhausts 100%, it's just the R3 we're not sure about but on the evidence above it would suggest it has a single exhaust.
 
I would imagine the exhaust system is devoid of any cat and so to have two exits would just be a waste of time/weight.

Actually looking at the below it might still have the centre cat:
