Paired with the matching Dinan axle-back exhaust the tone sharpens further into an aggressive growl reminiscent of the Dinan E9x M3 racing middle exhaust — the same custom \"X\" design carried over to the F8x chassis. Unlike the stamped X-pipes common in the marketplace, the Dinan \"X\" is engineered for maximum flow.\u003c\/p\u003e\n\u003cp\u003eThe X-Pipe removes the factory center section behind the secondary catalytic converters, including the large resonator, replacing it with straight-through mandrel-bent 2.75\" T304 stainless steel tubing and the custom crossover. The kit ships complete with mounting hardware, OE-quality clamps and flanges.

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.
