Welcome to the Valvetronic Designs cat-back exhaust system for the F87 M2C platform, or in other words, the solution to the S55 sound problem. For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. As the M2 Competition has the same problem as its big brother, we had to develop a solution for it. Our mission has been to find this hidden sound and allow all F87C owners to enjoy it. This full catback is comprised of a 2.75″ equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through our quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving and not alerting the Karens. This system mounts up to factory mounting points and is a direct bolt-on. It’s time to make your M2 Competition sound like it always should have.

Sound Developments.

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 configuration 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.
