You may need a stage 2 tune if the Cat isn't very efficient, or you may see a P0420 catalyst efficency below threshold code with the engine light on.

Hi,

I had this setup originally with a stage 1 map its plenty loud enough with out the drone and had no problems.  Just had my mapper delete the O2 Sensors.

A 200cel sports cat sounds lovely even with the rest of the exhaust being completely stock. Ever so slightly slouder but you wouldn't notice it unless you were driving with the windows down. It gives the exhaust note a nice rasp, not the annoying 1.0 fiesta type but the performance engine type.

I've got one from MPDevelopments and it sounds great, no drone. Rest of exhaust is stock. Make sure you get an adapter as the stock exhaust is a weird size.

You should definitely get a remap to take full advantage of the sports cat, otherwise the hp improvement is negligible. And make sure the CEL is mapped out.

I did this at the start it stung me with an eml light immediatly.  My mapper removed it and hasn't come on since.
