(These figures are all from C&D's instrument tests.)

So, the M2 is "barely louder" than a 340i, and the 340 itself is "barely louder" than a luxo-barge E350. Based on this, it seems to be that we don't need to be too concerned that the M2 will be a loud car on the highway.
Damn, this means I have to get the M Perf Exhaust or Akra...

One thing I am a little worried about is that the M2 is not going to be loud enough. Even my brother's 991 GTS was not loud enough, hehe! The GT4 is a loud car when you get up there in the mid-range, with the PSE button on. And it sounds so beautiful in tunnels....

That's ok... I was't expecting it to be like the GT4 in the sound dept. But it will be fun doing a few mods to the M2.

Reminds me, I do want to hear a GT350R one day if possible. Another current car I really like from what I've seen...
