Active Autowerke has been an industry leader in engineering high quality BMW performance products for over 41 years. Dedicated to improving enjoyment of your driving machine with the highest quality products, Active Autowerke has been recognized as the leading BMW innovator. Our philosophy on developing refined BMW performance parts and making them available to the larger BMW community is highlighted by our most recent R&D program focused on improving the sound of the S55 exhaust. This R&D has resulted in the development of the Active Autowerke F80 M3 and F82 M4 equal length mid-pipe (US Patent 11248511, patent pending in UK and EU) the other option to our world famous F8X single mid-pipe.
WE ARE RECOMMENDING TO OWNERS OF CARS WITH AFTER-MARKET DOWNPIPES TO USE THE RESONATED VERSION BUT WE HAVE ONLY TESTED WITH THE STOCK REAR EXHAUST AND ACTIVE MAAD MAXX EXHAUST. WITH STOCK DOWNPIPES, THERE IS MINIMAL RASP. WE DO NOT GUARANTEE RESULTS WITH OTHER MAKES OF REAR EXHAUSTS.
• 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
