Thanks guys. And BTW - I know a m3 will never sound like a Ferrari - my hope was trying to convey that I'm after that higher pitch exotic sound vs the low and loud bark of large liter/cubic inch V8's.
Last year at the Montreal F1 there were some sweet cars downtown revving while waiting for the traffic lights. The small high rpm V8 sounds (to me) so much better than the giant lumpy bark of the
big motor cars. Just my humble opinion.

Anyway - other than cold start the stock system is all but silent.

I worry a little about MPE reputation to crack.

Likely will pull the trigger and order Monday. Considering ceramic coating.
