M perf dB?

Who can quantify how loud the M perf exhaust is?

I picked my 335i with M-Performance Exhaust two days ago. I've only got 200 miles on it, but it's disappointingly quiet. I hope it breaks in and gets louder.

Mind you that's with windows up its 78-82db at WOT.

Idle is about 50db.

Windows down is probably much higher.

It's not too bad...but clearly not obnoxiously loud.
