I seen the video of the straight pipe 750 and I don't think the guys doing the jobs are reputable.

An exhaust tech should know before hand how a twin turbo engine would react to a resonator delete and a muffler delete.

Best option which is probably the most expensive option is cat-less downpipes and an X pipe instead of the resonator while leaving stock mufflers on.

This gets expensive because of the added tune you would need to hide the check engine for the O2 sensors but you get non restricted airflow and pure turbo spool with the aggressiveness in sport mode.

I have catless DP on now with everything else stock and it sounds great. Thinking do to the X pipe now instead of the resonator.
I kept stock downpipes and went with a custom full exhaust on my G12 750i. Sounded amazing and no drone. X Pipe to aftermarket mufflers.
What brand mufflers did you get?

Only reason I'm not switching from the M muffler is because of the valves and the way it sounds in sport mode. Sounds too good during downshifts. Did you have the M muffler too stock?
I didn't have M mufflers and I went with a custom setup from Kinneys Muffler shop in Watauga, TX. I would highly recommend replacing stock mufflers with Vibrant Race Mufflers which are similar to Kinneys. I had them in my Hellcat Charger and F10 M5. Sounds amazing.
