A power mower is about 94 db. My Roadster is much louder than my 435i with MPPK and the M Performance muffler. I autocross my Roadster and we record sound during an autocross. I don't recall my exact numbers, but it is between 70-75 db. I really don't think installing an MPPSK will be anywhere close to 95 db.
