Removed the center balance pipe connecting the 2 mufflers and capped the muffler hole. Car sounded more aggressive and meaner.

But as usual it wasn't enough and after watching the dinan X pipe the game plan has somewhat changed.

Ordered today:

Dinan X Pipe
EVO RWs Secondary Cats

Probably will keep the current muffler setup unless end up making a deal on used AWE track exhaust posted for sale currently. If the deal happens great if it doesn't then will be happy with above plan regardless.
Try this out first. See how you like it and if there is any drone. If you feel it's not enough then get the exhaust.

On my old C63, I removed the resonator first and replaced with a straight pipe. Wasn't enough so I removed the secondary cats and replaced with straight pipe. Still wasn't enough so I went with Catless Long Tube Headers. Then it was finally enough lol. Only thing left to do was removed muffler but that would have caused drone on that car.
I'm glad I'm not the only one with these planned mods lol. The petrol head is embedded in a lot us lol and the car project is always evolving.
