Sound Devlopments.
At Valvetronic Designs, we are chasing perfection and we believe this our equal-length exhaust setup is the sound solution for F8x owners. Traditionally equal length exhaust configuartion lowers the aggressive nature of the S55 engine. With this new design we have spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but with the equal length configuration, allows for the sound to be very pleasurable rather than just loud. Owners coming from other non equal length setups will not feel short-changed in regards to this setups volume.
