ER downpipe - mid w/o silencer and rearsilencer

Hi Guys,

First of all, sorry for my English.
I'm the owner of a BMW M135i. Fitted some oz Ultraleggera's, H&R springs, performance lights, steeringwheel, side skirts etc...

I have a Catless downpipe from ER. Bastuck midsection without silencer and bastuck rear silencer.

I really love the sound. Nice pop and bangs when off throttle and upshifts. But the drone at low revs is getting annoying.

What would you guys do to avoid drone but to keep the loud noise when you want it too? Is it true that the drone caused by the midsection with no silencer?
Thinking of:
ER downpipe - stock midsection - bastuck rear silencer
ER downpipe - midsection without silencer and stock rearsilencer (to close the valve?)

Bastuck also offers a midsection with a small silencer, but don't know if it's avoids the drone.

I want the bangs and pops when upshifting and off throttle. But delete the drone.

Thanks for your opinions and help guys!

Ps: posted my question in this section, cause at the f21 section it's quite calme :D maybe this info is also interesting for m235i owners.
