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.\u003c\/p\u003e\n\u003cp\u003eThe 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!\u003c\/p\u003e\n\u003cstrong\u003e\u003cstrong\u003e\u003ca title=\"bimmer post active autowerke m4 exhaust review\" href=\"http:\/\/f80.bimmerpost.com\/forums\/showthread.php?t=1194246\" target=\"_blank\"\u003eSee what actual customers are saying on BimmerPost!\u003c\/a\u003e\u003c\/strong\u003e\u003c\/strong\u003e\n\u003ch2\u003e\u003cstrong\u003eKEY FEATURES\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e18+ WHP over stock\u003csup\u003e*\u003c\/sup\u003e\n\u003c\/li\u003e\n\u003cli\u003e30+ LB-FT over stock\u003csup\u003e*\u003c\/sup\u003e\n\u003c\/li\u003e\n\u003cli\u003eImproved performance from less back pressure\u003c\/li\u003e\n\u003cli\u003eDeeper \u0026amp; throatier exhaust note\u003c\/li\u003e\n\u003cli\u003eLess restrictive, more free flowing\u003c\/li\u003e\n\u003cli\u003eLighter weight than factory system\u003c\/li\u003e\n\u003cli\u003eQuicker turbo spool\u003c\/li\u003e\n\u003cli\u003eIncreased low end and mid-range power\u003c\/li\u003e\n\u003cli\u003eSingle-pipe design eliminates cheap weed-eateru00a0sound from factory exhaust\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* \u003cem\u003e\u003cstrong\u003ePerformance gains when paired with \u003ca title=\"F8X BMW M3\/M4 Performance Exhaust\" href=\"http:\/\/store.activeautowerke.com\/products\/f8x-bmw-m3-m4-rear-exhaust\" target=\"_blank\"\u003eActive Autowerke F8X Rear Exhaust Section\u003c\/a\u003e\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eMUSTANG DYNO RESULTS:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/c1.staticflickr.com\/1\/628\/21607095396_132b0d3266_c.jpg\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eModifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eActive Autowerke F8X Mid Pipe\u003c\/li\u003e\n\u003cli\u003eActive Autowerke F8X Rear Exhaust Section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eF8X BMW M3\/M4 Exhaust Results:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003eRED Line Stock Figures: 380 \u003cem\u003eWHP |\u003c\/em\u003e 371 \u003cem\u003eWTQ\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #0000ff;\"\u003eBLUE Line Full Active Autowerke Exhaust: 398 \u003cem\u003eWHP\u003c\/em\u003e | 401 \u003cem\u003eWTQ\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ffd966;\"\u003eGOLD Line Full Active Autowerke Exhaust Run 2: 397 \u003cem\u003eWHP\u003c\/em\u003e | 398 \u003cem\u003eWTQ\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: \u003cem\u003eActive Autowerke Full Exhaust System is recommended for, BUT NOT LIMITED TO, off road or racing applications.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003ePERFORMANCE MID PIPE REDESIGN\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eBMW 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.\u003c\/p\u003e\n\u003cp\u003eUpon 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.\u003c\/p\u003e\n\u003ch2\u003eM3\/M4 MID PIPE PERFORMANCE ADVANTAGES\u003c\/h2\u003e\n\u003cp\u003eIn 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.\u003c\/p\u003e\n\u003cp\u003eUnlike 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:\u003c\/p\u003e\n\u003cp\u003eFirst 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!\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/dlg0xVQCMH4\" width=\"560\" height=\"315\" allow=\"autoplay; encrypted-media\" allowfullscreen=\"\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/G8FnS5VGlGM\" width=\"560\" height=\"315\" allow=\"autoplay; encrypted-media\" allowfullscreen=\"\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eu00a0\u003c\/p\u003e\n\u003cp\u003e\u003ca title=\"How to install the Active MID PIPE to the factory rear exhaust\" href=\"http:\/\/images.activeautowerke.com\/Installation%20PDF's\/F80%20-M4-M3%20MID-PIPE%20ISTALLATION%20WITH%20STOCK%20EXHAUST%2011%204%2015.pdf\"\u003e\u003cimg alt=\"\" src=\"\/\/cdn.shopify.com\/s\/files\/1\/0578\/5357\/files\/pdf-icon_small.png?5194202583727197452\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"sb-car-tag-by-description\" style=\"display: none;\"\u003eyear-2014,year-2014-make-bmw,year-2014-make-bmw-model-m3,year-2014-make-bmw-model-m4,year-2015,year-2015-make-bmw,year-2015-make-bmw-model-m3,year-2015-make-bmw-model-m4,year-2016,year-2016-make-bmw,year-2016-make-bmw-model-m2,year-2016-make-bmw-model-m3,year-2016-make-bmw-model-m4,year-2017,year-2017-make-bmw,year-2017-make-bmw-model-m2,year-2017-make-bmw-model-m3,year-2017-make-bmw-model-m4,year-2018,year-2018-make-bmw,year-2018-make-bmw-model-m2c,year-2018-make-bmw-model-m3,year-2018-make-bmw-model-m4,year-2019,year-2019-make-bmw,year-2019-make-bmw-model-m2c,year-2019-make-bmw-model-m4,year-2020,year-2020-make-bmw,year-2020-make-bmw-model-m2c,year-2020-make-bmw-model-m4,year-2021,year-2021-make-bmw,year-2021-make-bmw-model-m2c\u003c\/div\u003e","brand":"Active Autowerke","offers":[{"title":"non-resonated","offer_id":51011864232210,"sku":"11-037 KIT","price":799.0,"currency_code":"USD","in_stock":false},{"title":"resonated","offer_id":51011864264978,"sku":"11-037R KIT","price":999.0,"currency_code":"USD","in_stock":false},{"title":"with exhaust dump","offer_id":51011864297746,"sku":null,"price":1799.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/4220\/0082\/files\/F80wdumpa_2d6dda69-fb70-4afe-a974-ec8427e4ebda.jpg?v=1740692864","url":"https:\/\/merakiautoworks.com\/products\/f8x-bmw-m3-m4-mid-pipe","provider":"Meraki Autoworks","version":"1.0","type":"link"}
