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 ?

Hi...I assume Cheifski is relating to me in his post above!
I've put in 200 cell primary race cats (quite neatly actually - to ensure it looks stock, they've been inserted into the stock AMG cat housing). Amazingly, the standard cats are 750 cell and they look so restrictive that it's a wonder any flow gets past them! They make the sound a bit harder and more aggressive when the engine is under load but my main criteria was no extra noise so the difference between mine and stock, sound wise, is minimal.
Power wise it's said to be worth 30-40hp (with bigger manifolds - the standard ones are VERY restrictive) - mine has larger 3" manifolds to assist with the flow into the cats which is basically CLK Black Series spec and one of the main reasons (other than ECU variations) why the C63 is slightly down on power compared to other '63 engined AMG's. I haven't had it dyno'd yet but in all honesty I don't need to - my butt dyno tells the difference very clearly and thats not something you can usually say when talking about relatively small power gains in a 500hp car that isn't turbocharged!
