3" exhaust is just stupid on a v6. Trust me that factory AMG exhaust is plenty for the srt6 up to 350-400 hp. we are talking about street cars, not race cars.
stock on a c320 is 2.5" on a c32 amg piping is 2.75" if your interested.
100 cell high flow cats are better than "removing it" like you said, its a street car not a race car.
