Performance Mid Pipe Redesign
BMW applied two silencers in the middle and rear of the factory F87 exhaust system to assist with noise dampening. The middle silencer has a small crossover internally. This helps with drone, however, it is also quite restrictive and amplifies the uneven, out-of-sync turbocharger sound that many owners have complained about.
Upon analysing the F8X exhaust, we came to the decision that we can accomplish more with much less – therefore designing our M2C exhaust started with the highly restrictive mid pipe. With our design, we were able to drastically increasing exhaust flow, while virtually eliminating the "dueling 3-cylinders" sound.
M2 Competition Mid Pipe Performance Advantages
In order to get the most possible gains, we had to apply some trade secrets to our mid pipe design – many of our competitors have done the same. However, we wanted our F87 Mid Pipe to stand out from the rest.
Unlike the design of the factory mid pipe, and the mid pipes of our competitors, we decided on a singular pipe design. This was for a few reasons:
First and foremost, to cancel out that cheap weed eater sound that is so frequently complained bout. Not only does this design cancel out the un-M3-like sound, it creates a deeper, more harmonious sound that most have come to expect from a performance car built by the ///M Division. Naturally, with this increased flow – we were able to pull out a surprising amount of power. Eliminating this extra pipe also allowed us to save some valuable weight, which as you know, translates to improved performance!
