The MagnaFlow Stainless Steel, Straight-Through Universal Muffler # MF12588 is a straight through style of muffler whereas the Flowmaster 40 Series is a chambered style. Flow through mufflers are always louder than chambered mufflers so the part # MF12588 would be louder. The # MF12588 will flow better though and will produce more power.
