Can you please elaborate on drone? Is that the noise heard in the car on the highway at a constant rpm?

straight pipes are very raspy, sound really bad. If i was you buy a magnaflow xpipe and replace the resonators with it. Your car will sound great

MB C-300 Sport 2009 Manual Black XPIPE+Exhaust
straight pipe is cat back usually no resonators no mufflers and no point for an Xpipe if you do a straight pipe I had one on my 08 Audi S line a4, I have an Xpipe with straight pipes instead of mufflers on my current C 300 here is the vid.

I think xpipe because it will be more raspier but than again straight pipes would have a better flow.

Straight pipes actually have worse flow. The exhaust pulses from each bank mixing in the x-pipe actually improves flow. Straight pipes leave a low pressure pulse in between each high pressure pulse which increases backpressure.
