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\u0026amp;D program focused on improving the sound of the S55 exhaust. This R\u0026amp;D has resulted in the development of the\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cstrong\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eActive Autowerke F80 M3 and F82 M4 equal length mid-pipe\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003e\u003cspan\u003e \u003c\/span\u003e(patent pending) – the other option to our world famous F8X single mid-pipe.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eAn 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 addition 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.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eInitial 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 our expertise in having already developed a single mid-pipe system for the F-series M cars and devoted our R\u0026amp;D resources into developing the mid-pipe solution which you see here.\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e\u003cspan color=\"#000000\"\u003eOur R\u0026amp;D looked at the ways this could be done and while making up the difference in the rear section of the exhaust seemed like the most logical place, it would require a brand new rear exhaust system and we were aware that many BMW owners would not like this option. So we looked at adding length to the passenger side midpipe section and creating a new crossover section to create an exhaust note that's never been akin to the \"S55 sound\". \u003c\/span\u003e\u003c\/span\u003eUsing a patented solution of a crossover with sinusoidal pipes allowed us to correct the downpipe length variance before mixing the sounds giving the expected 6 cylinder sports car exhaust notes.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eThe 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\".
