Sounds about right. I dynoed my M3 at Carbconn back in 2009 when I lived in Seattle. Stock with just Eisenmann muffler and drop in filter it put I believe 338whp and then with aftermarket Fabspeed high flow cats, Eisenmann, and filter it put down 362whp from what I remember. Definitely impressive numbers for the 1M!
