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.

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\u003ch4\u003eM3\/M4 MID PIPE PERFORMANCE ADVANTAGES\u003c\/h4\u003e\n\u003cp\u003eIn order to get the most possible gains, we had to apply some trade secrets to our mid pipe design – many 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 bout. 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 \u003cp\u003e\u003ca href=\"https:\/\/svbimmer.com\/pages\/emissions-notice\" target=\"_blank\"\u003e\u003cstrong\u003eVIEW EMISSIONS NOTICE\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Active Autowerke","offers":[{"title":"Non Resonated","offer_id":41776707797192,"sku":"11-037","price":799.0,"currency_code":"USD","in_stock":true},{"title":"Resonated","offer_id":41776707829960,"sku":"11-037R","price":999.0,"currency_code":"USD","in_stock":true},{"title":"w Exhaust Dump","offer_id":43954368053448,"sku":"11-037D","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0210\/4203\/6785\/files\/Active-Autowerke-F80-F82-BMW-M3-M4-Midpipe.jpg?v=1768904404"},{"product_id":"active-autowerke-f87-bmw-m2-competition-mid-pipe-11-050","title":"Active Autowerke F87 BMW M2 Competition Mid Pipe Includes Active F-Brace","description":"\u003ch4\u003eACTIVE AUTOWERKE AA F87 BMW M2 COMPETITION MID PIPE\u003c\/h4\u003e\n\u003cp\u003eActive Autowerke has been an industry leader in engineering high quality BMW performance products for over 30 years.

If one could eliminate some or most of this exhaust back pressure, the turbo will spool that much faster and effortlessly resulting in quicker engine revs and increased HP. The Active Autowerke Signature down pipes are designed with the intent to maximize power. These down pipes are created with the least amount of restrictions possible by utilizing a full 3\" piping throughout with the least amount of bends possible. What you will experience is a faster, more responsive engine because the turbo impeller now has the ability to spool that much faster. The end result is more power. Made from 304 stainless steel the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Liberation Serif, serif\"\u003eThis variant includes a pair of 4.5\" ultra high flow GESI catalytic converter that will NOT produce a CEL!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000000\"\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eThe GESi G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate.

Every effort was made to ensure that the midpipe would work with the stock exhaust and enhance the sound with a deeper tone. We believe our midpipe together with our rear exhaust offers the best combination of sound and performance versus other systems on the market today.

being flashed back to OEM-specs by a BMW dealer became quite problematic. A manufacturer software issue locked the devices into Write Mode after the first tune was written to the vehicle. Getting the tool back into the proper \"Read Mode\" was a complicated endeavor; we knew our next programming tool would have to have the flexibility to ALWAYS READ AND WRITE AT ANY TIME.\u003c\/p\u003e\n\u003ch3\u003eValue\u003c\/h3\u003e\n\u003cp\u003eCompared to the G5 and the SIMON 3, the SIMON 4 has a much more consumer-friendly price, making it much easier to bundle the tool with a file tune or two (or three!) for your BMW.
