Active Autowerke has been an industry leader in engineering high quality
BMW performance products for over 41 years. Dedicated to improving
performance with the highest quality products, Active Autowerke is
synonymous with making power. Our philosophy on developing refined BMW
performance parts, with power in mind, and providing them to a large BMW
community can be best characterized by our F80 M3 and F82 mid pipe a
valuable addition to our F8X BMW collection.
The Active Autowerke F8X Mid Pipe was specifically designed to eliminate
the highly restrictive nature of the OEM F80 M3 and F82 M4 mid pipe thus
creating optimal exhaust flow and drastically improving performance. In
addressing the annoying sound ( described by many like that of a weed-eater
) we needed to better understand the issue. After much research and testing
we discovered the synchronization of the Turbos as the main factor in the
sound. The solution was a single mid pipe which eliminated much of the
annoying sound. The next challenge was making a large 3.5" pipe ( needed
for optimum performance ) fit without ground clearance issues - thus the
oval pipe. Engineered for an exact fit on both the F80 M3 and F82 M4, the
difference in power with this mid pipe will be noticeable the moment it is
installed!

BMW applied two silencers in the middle and rear of the factory F8X 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 analyzing the F8X exhaust, we came to the decision that we can
accomplish more with much less therefore designing our F80 M3 and F82 M4
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.
In order to get the most possible gains, we had to apply some trade secrets
to our mid pipe design u00a0many of our competitors have done the same.
However, we wanted our F8X 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 about. 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!
