Description
Active Autowerke has been an industry leader in engineering high quality BMW performance products for over 39 years. Dedicated to improving enjoyment of your driving machine with the highest quality products, Active Autowerke has been recognized as the leading BMW innovator. Their high level R&D has resulted in the development of the Active Autowerke F8X M3 & M4 equal length mid-pipe – the other option to our world famous F8X single mid-pipe.


An inline 6 engine naturally has an evenly spaced exhaust pulse which results in a more smooth and full sounding noise. However, the twin turbo setup of the S55 engine while producing additional power has created a sound which sounds more like 2 independent inline 3's competing for noise than the throaty sound one would expect. The variance between the lengths of the front and rear down-pipes of almost a foot and a half creates unevenly spaced pulses so that when the merge in any form of crossover system whether stock, x-pipes, double x-pipes, single mid-pipe or rear-section solutions. Since the sound waves are moving at the same rate when they exit the system, these crossover sections are simply creating a higher pitched sound resulting in the annoying sound some have referred to as a weed eater sound. The current systems allow the banks to merge unequally pulsed sounds and after much research and testing (from many BMW experts) it was determined that equalizing the length of the exhaust pipes before mixing was a solution to this sound problem.

Initial exhaust solutions focused on correcting this variance in the space behind the differential housing with one complaint being the inability to keep existing rear exhaust systems. Active Autowerke decided to leverage their expertise in having already developed a single mid-pipe system for the F-series M cars and devoted our R&D resources into developing the mid-pipe solution which you see here.
The Active Autowerke F8X Equal Length Mid Pipe was specifically designed to create equal length exhaust pipes adjusting for the difference between the front and rear banks of the F80 M3 and F82 M4 down pipes before mixing in an X-pipe and creating an exhaust note different from the normal "S55 sound". Engineered for an exact fit on both the F80 M3 and F82 M4, the difference in sound with this mid pipe will be noticeable the first time with an open throttle!

PLEASE NOTE: IT IS STRONGLY RECOMMENDED THAT CARS WITH CATLESS (STRAIGHT-THROUGH) DOWNPIPES USE THE RESONATOR OPTION FOR THE EQUAL LENGTH MIDPIPE.


KEY FEATURES
Lighter weight than factory system
Quicker turbo spool
Increased low end and mid-range power
Equal length design eliminates the pulsing sound caused by the unequal length down pipes

Description
Active Autowerke has been an industry leader in engineering high quality BMW performance products for over 30 years. Dedicated to improving performance with the highest quality products, Active Autowerke is synonymous with making power. Their 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 ) they needed to better understand the issue. After much research and testing they 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!
