Nothing to do with me but considering many M owners are looking for a little more noise itl be interesting to see where these end up in relation to the ones offered from BCS @ £688 :?

Nah, I think that's the Eisenmann Race ones.

I've got these and don't found them overly loud - and they only blow about 86db on the static noise test at the track.
