I have a Magnaflow (2-1/2 in - 2X 2-1/4 out) it sounds great without being too loud. Flowmaster 40 sounds good, but will be too loud for my taste. I also kept the first resonator - that keeps the sound really smooth, no raspiness of any kind - just V6 music

. I followed the recommendations of the installer (Muffler King in Kirkland WA) for a good sounding exhaust that would not be obnoxiously loud. I love it
