I was referring to the audible difference but they will also transmit more vibration into the car. Vibration in the car is really only noticeable at idle, more so with the a/c running or if the car is idling rough such as if you have a vacuum leak or something. I had the idle on my car bumped up to 900 rpm to reduce the SC'er rumble at idle well before upgrading the mounts though so I don't really get much vibration at idle but the lower stock idle speed will probably lead to more vibration as indicated by vI6cious.

this makes sense, but in concern for my own build... what wakes the dead? what exhaust is after your headers?
well my catless headers with a stock exhaust and no name muffler and 1 resonator removed it sounds very very good not too loud but when you open up it hits all the perfect notes. when i added the cams it really opened up the growl at all speeds and yes its very very mean but i really like it.

im a teenager and i dont mind loud so i dont think i will have an issue with bw mm but the vibrations i bet could get on my nerves if i start driving more city

If you want to upgrade, but worry the vibes will be too much do the M3 MM.

The vibes though from the BW MM, at speed are actually kinda sexy. It just sounds and feels a bit more race like compared to OEM, but it's really not over the top unless you are sitting in stop and go with your AC on. Then it can be pretty annoying
