Cat-back Resonated VS Cat-back Non-Resonated system, for Clio 197

Non-resonated if you enjoy bleeding out of your ears, otherwise resonated although even some of the resonated ones can drone a bit.
 
Scorpion resonated on mine. Plenty loud enough for the driving I do - fairly civilised round town, but great when you use all the revs. Does have a tendency to drone on the motorway, but thankfully I don't do a lot of that kind of driving. Non-resonated are cheaper if you buy brand new....
