The twin turbo S55 has almost a foot and a half of difference between its front and rear bank downpipe lengths, giving unevenly spaced pulses and the higher pitched weed eater note owners describe. Rather than correcting that behind the differential housing, which would have required a completely new rear exhaust, Active Autowerke adds length to the passenger side mid-pipe and uses a patented crossover with sinusoidal pipes to equalise the lengths before mixing — delivering the note expected of a six cylinder sports car while retaining your existing rear exhaust.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEqual length design corrects the roughly 18\" length variance between the front and rear bank downpipes before the crossover\u003c\/li\u003e\n\u003cli\u003ePatented crossover using sinusoidal pipes — US Patent 11248511, UK and EU patent 3882441\u003c\/li\u003e\n\u003cli\u003eGen 2 revision adds specially developed resonators (resonated option) that remove rasp with minimal change in sound volume and reduce 2k buzzing\u003c\/li\u003e\n\u003cli\u003eLighter weight than the 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\u003eRetains the existing rear exhaust section\u003c\/li\u003e\n\u003cli\u003eTested with stock and Active Autowerke downpipes and with stock and Active Autowerke rear exhausts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eActive Autowerke Gen 2 Equal Length mid-pipe assembly\u003c\/li\u003e\n\u003cli\u003eComplete kit as supplied by Active Autowerke; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Active Autowerke specifies no additional hardware for this part — it installs between the downpipes and the existing rear exhaust.\u003c\/li\u003e\n\u003cli\u003eCars running catless (straight-through) downpipes: Active Autowerke strongly recommends the resonated version of the EL mid-pipe.

It was designed to eliminate the highly restrictive OEM mid pipe and create optimal exhaust flow, and to address the thin, buzzy weed-eater note of the factory system — considerable research identified the synchronisation of the turbos as the main factor, and a single mid pipe eliminates much of it. The pipe is oval so the large 3.5\" section needed for optimum performance fits without ground clearance problems, with an exact fit on both chassis.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e18+ WHP over stock\u003c\/li\u003e\n\u003cli\u003e30+ LB-FT over stock\u003c\/li\u003e\n\u003cli\u003eSingle 3.5\" oval pipe design, shaped to clear the underbody without ground clearance issues\u003c\/li\u003e\n\u003cli\u003eSingle-pipe design eliminates the cheap weed-eater sound of the factory exhaust\u003c\/li\u003e\n\u003cli\u003eLess restrictive and more free flowing than the OEM mid pipe\u003c\/li\u003e\n\u003cli\u003eImproved performance from reduced back pressure\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\u003eDeeper and throatier exhaust note\u003c\/li\u003e\n\u003cli\u003eLighter weight than the factory system\u003c\/li\u003e\n\u003cli\u003eOffered with or without resonators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eActive Autowerke F8X mid pipe assembly\u003c\/li\u003e\n\u003cli\u003eRear section A\u003c\/li\u003e\n\u003cli\u003eRear section B\u003c\/li\u003e\n\u003cli\u003eBall clamps (2)\u003c\/li\u003e\n\u003cli\u003e65mm clamps (2)\u003c\/li\u003e\n\u003cli\u003eActive F-brace, per Active Autowerke's current kit specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Active Autowerke specifies no additional hardware for this mid pipe — the clamps needed to join it to the factory rear exhaust are supplied in the kit.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/active-autowerke-11-037-f8x-mid-pipe-installation-instructions.pdf?v=1787172586\"\u003eActive Autowerke F8X M3 \/ M4 Mid-Pipe installation instructions with stock rear exhaust (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eActive Autowerke's complete installation library: \u003ca href=\"https:\/\/store.activeautowerke.com\/pages\/instructions\"\u003eActive Autowerke — Installation Instructions\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eThe original listing carried no fitment chart; the table above reflects the F80 M3 \/ F82 M4 \/ F87 M2 application stated by Active Autowerke.

It also addresses the thin, buzzy factory note many owners describe as sounding like a weed-eater; after research and testing Active Autowerke traced it to the synchronization of the two turbos and answered with a single mid pipe, using an oval section so a 3.5 inch pipe could be fitted without creating ground clearance problems. Engineered for an exact fit on the BMW M2 Competition, the difference in power is noticeable the moment it is installed.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e18+ WHP over stock\u003c\/li\u003e\n\u003cli\u003e30+ lb-ft of torque over stock\u003c\/li\u003e\n\u003cli\u003e3.5 inch single-pipe design, oval section for ground clearance\u003c\/li\u003e\n\u003cli\u003eLighter weight than the factory system\u003c\/li\u003e\n\u003cli\u003eDeeper, throatier exhaust note; single-pipe design removes the factory weed-eater sound\u003c\/li\u003e\n\u003cli\u003eLess restrictive and more free flowing, for reduced back pressure and quicker turbo spool\u003c\/li\u003e\n\u003cli\u003eIncreased low-end and mid-range power\u003c\/li\u003e\n\u003cli\u003eAvailable with straight pipes or resonated pipes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMid-pipe\u003c\/li\u003e\n\u003cli\u003eRear section (A)\u003c\/li\u003e\n\u003cli\u003eRear section (B)\u003c\/li\u003e\n\u003cli\u003e2 x ball clamps\u003c\/li\u003e\n\u003cli\u003e2 x 65 mm clamps\u003c\/li\u003e\n\u003cli\u003eActive F-brace\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Active Autowerke specifies no additional hardware for this mid pipe; the Active F-brace and all clamps are included in the kit.\u003c\/li\u003e\n\u003cli\u003eInstaller supplies basic hand tools and a lift or jack stands; no cutting or welding is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/active-autowerke-11-050-installation-instructions.pdf?v=1787172762\"\u003eActive Autowerke F87 M2C mid pipe installation instructions (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/store.activeautowerke.com\/pages\/instructions\"\u003eActive Autowerke installation instruction library\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eQuoted power and torque figures are Active Autowerke's own test results and will vary with the rest of the car's exhaust and tune.
