Custom Exhaust Solutions

On my 2009 328i I have secondary cat delete, resonator delete, and a magnaflow muffler. I have changed my mind about this set up. It is just a bit loud, and occasionally drones. I have a couple of ideas to handle this right now.
1.) Install X-Pipe as close to the manifold as possible.
2.) Install aftermarket resonators/straight-though mufflers behind possible X-pipe
3.) Reinstall factory resonator
or any combination of these three. I'm here for your opinions
