I've got an e93 325 which has the same direct injection 3.0 unit (albeits detuned to 218hp) and I have to say that the engine note is not that great. I had an e46 325 vert a few years ago and that sounded wonderfull on full song.
We've just come back from a trip to Italy where they have a lot of tunnels and a few times with the roof down I changed down gears and let rip but it wasn't that impressive. My 15 year old now calls it the milkfloat because the noise it made was so poor.
I was looking for a sports exhaust to see if this would make any difference but to date no joy.
My advice if the exhaust note is important to you is try before you buy.
