I'm sure you can put a few resonators in there to minimize the droning.
Did your RDsport (is that right) system have any droning at any rpm/acceleration/deceleration conditions?

What can be done to eliminate droning altogether, or at least droning below 2500 rpm? Will going with larger mufflers in additional to a box resonator (chambered) do the trick? I was thinking about putting back the OE box resonator behind the x-pipe and see if that will do the trick. The last thing I want to do is replacing the mufflers with with larger ones.

E63 has one resonator. It has primary and secondary cats like the M5. I don't think it drones at all, well maybe a little bit around 2K rpm. Can't really remember b/c it's a garage queen.
I believe there are hybrid x-pipe/resonators available to help out with the droning. I don't think the RDSport exhaust droned at all. I loved the sound of that exhaust. Frederico, of RDSport, was supposed to fabricate an exhaust for my E63 but I can't wait months for it. So, I went and got the Renntech. I'm hoping it gets done so I can sell the Renntech when it becomes available.

On the e63 and m5, I'm wondering if all the stock components are active during low engine rpm. Under considerable acceleration, it growls harder which may indicate additional opening of airflow on the exhaust system - somewhere. On the 545i, it's the second muffler.

Bimmer32,
Here is the hybrid xpipe that Joe might mean

This would help reduce droning. Please keep us updated.

Evening times are short now, but I should have some more video clips by Friday. As always, detail . . . detail description.

WOW. An x-pipe in a muffler/resonator casement. If the stock box resonator won't do the trick, I'll try this baby out. Thanks for the link. At this point, I'm willing to go with tube and chamber resonators to rid the droning and louder than desired idle sound level. Right now, the idle sound level is just a tad lower than a diseal rig. I should get a db meter.

This looks nice. If you try it, let me know. the sound is cool and all, but after a while it is freaking loud. hahaha.
