Decat C63 ?

[christmc]

I have just bought a new C63 pp and would like to know if anyone has de catted theirs of if it makes a significant difference to the exhaust . Its sounds fantastic anyway but i just wonder if it is worth it?

It's paladium silver ( Gun Metal Grey essentially ) upgraded 19" alloys, command, rev camera , bi xenon headlights , harman karden upgrade sound, and the merc performance pack upgrade. So running roughly 487-490bhp

I have to be honest i dont know what sports cats would actually do i thought cats were just for filtering ozone harmful toxins.

So do they sound different to the standard ?
