Sounds awesome, but per the BMW norm pricey…
Or just spend $100 on a sawzall, $20 on blades, $80 on pipe, $100 on exhaust tips, and $40 to have someone weld the pipe and tips on and have a better sounding exhaust for under $400 with another tool added to your garage.

Removing resonators/cats off my m5 helped the sound a ton
Your car sounds like a sport bike, not exactly the sound I would want from a large V10. Don’s sounds much better. I guess it’s all subjective
X…
e60’s with just the mufflers removed sound PERFECT.
I have to agree with MDP, and that video would seal the deal if it were mine.
ill def concur with this statement.
thanks guys 
One thing I def learned is the whole exhaust video thing can be really misleading…the Eisenmann race with x-pipe sounded AMAZING in videos but was waaaaaayyyyyy too loud for me when I saw a guy in CT with one…and I wanted relatively loud! It sounded incredible but from the outside it looked like it would kill you from the drone. Not to mention I see them for sale all the time from people who were mislead the same way. Hearing it in real life gives you a better judgement of the volume and that’s a whole different story…
I bet removing the mufflers is loud but sounds good, however you won’t get 30whp doing that
