It's got me thinking about gutting or removing my muffler!

The drone is my second concern aside from cutting out my OEM muffler lol.

BTW... the video does no justice, this absolutely sounds amazing I get compliments everywhere I go. Will try to make a better video sometime this week or next.

Where would you add the resonator?

The BMW Performance Exhaust on my wife's 128i is really nice, although a bit loud. No drone, though. The Dinan free-flow on my E92 is just right, so I'm hoping this new exhaust will be about the same.

There are tons of videos on the M-performance exhaust. It sounds good but in my honest opinion, not that great. I've heard it in person and its like stock but a bit louder and deeper. Its worth a consideration, however.

I'm sure there is. The drone is an issue though.
