The 3.7L V6 Mustang is definitely a success. This car makes as much power as the earlier model V8's did using two less cylinders. These cars also react very well to performance upgrades such as tunes, intakes and exhaust. A cold air intake from JLT, custom tune from Jon Lund or one of our offroad midpipes yielded us a 30rwhp increase over stock. Magnaflow. Procharger also offers a supercharger kit for those looking to take their V6 to the next level. If sound is what you're looking for we also offer several different catback and axle back setups from names like Magnaflow, Pypes, Flowmaster, Borla and Ford Racing.
