S-Line Ferrari 458 Valvetronic
S-Line Vavletronic 458 system.
458 Owners can now enjoy the S-line sound with valve actuated mufflers! Enjoy the famous
S-line sound and have the ability to drive quietly when needed. Zero drone. This system is the same dB as stock but with that fantastic F1 scream. If you want to get a little more dB we recommend test pipes. (offroad use only). We also recommend the Forza valve control key fob actuator. (sold separately) This is the best of the best!
