The middle silencer has a small crossover internally. KEY FEATURES 18+ WHP over stock* 30+ LB-FT over stock* Improved performance from less back pressure Deeper & throatier exhaust note Less restrictive, more free flowing Lighter weight than factory system Quicker turbo spool Increased low end and mid-range power Single-pipe design eliminates cheap weed-eater sound from factory exhaust PERFORMANCE MID PIPE REDESIGN BMW applied two silencers in the middle and rear of the factory F8X exhaust system to assist with noise dampening. 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! The next challenge was making a large 3.5" pipe ( needed for optimum performance ) fit without ground clearance issues - thus the oval pipe. The solution was a single mid pipe which eliminated much of the annoying sound. After much research and testing we discovered the synchronization of the Turbos as the main factor in the sound. In addressing the annoying sound ( described by many like that of a weed-eater ) we needed to better understand the issue. 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. 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.
