I think its possible to replace them later.....they weight about....20lbs and they fit in my car. If you just take the resonators off without putting aftermarket exhaust, there is NO difference in sound. Only difference would be the extra airflow from the exhaust. Oh and I removed both resonators front and back. It cost me $150 and 1.5 hours for my local exhaust shop to make a pipe and weld them in place of the resonators. to be honest, I have NO idea how much of a sound difference resonator removal makes because I have not sat in a car with B&B AND resonators.

My experience was that removing resonators increased the hum of the exhaust at highway speeds. I only removed the large on and replaced it to get rid of the hum.

yep....minimal increase in humming....almost not noticeably in my opinion. JDN, does your exhaust still howl strong as the rpm increases??? I cannot get your video to play...

It's not a video any more, it's an MP3. Try an MP3 player and it should work. I play it with Window media player. I may have to remove it from the web site soon.

I heard this car the other day at startup and idle. It is quite loud (even for me). Definately a strong resonance tone throughout the lower revs, but very barky up to 3k rpm. It sounds very nice. As far as looks, the canisters are huge and full out the bumper cutout very nicely. Now I just want to hear it at full song pulling away from me. We msut so a little video shoot in the coming week Jeff. I think your car might be louder . Also, join us at our dyno meet in the near future. We would love to see what your car pulls in comparison to the new and old M5s.

I would imagine you get a pretty hefty vibration at highway cruising without the resonators???
