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 (straight pipes)\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 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.

of that potential back — slowing exhaust flow and, with it, turbo spool. The Active Autowerke B46 Signature downpipe for the 230i, 330i and 430i uses 3-1\/2 inch stainless steel piping for more power, quicker spool and durability, with a stainless flex joint feeding into the ball flare that meets the OEM exhaust system.

The sound is unobtrusive with a rich, mellow tone, and two Active Autowerke noise canceling chambers per muffler reduce the drone some mufflers emit at cruising speeds around 3,500 rpm.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDurable 100% 304 brushed stainless steel construction\u003c\/li\u003e\n\u003cli\u003eLarge 3-inch mandrel bent piping for maximum flow\u003c\/li\u003e\n\u003cli\u003eStraight-through design\u003c\/li\u003e\n\u003cli\u003eDouble-walled 76mm Signature stainless tips\u003c\/li\u003e\n\u003cli\u003eAdjustable tips with embossed Active Autowerke logo\u003c\/li\u003e\n\u003cli\u003eTwo Active Autowerke Noise Canceling Chambers (NCC) per muffler to reduce drone around 3,500 rpm\u003c\/li\u003e\n\u003cli\u003eGains of 5+ HP over stock configuration; additional HP with Active Autowerke programmed software\u003c\/li\u003e\n\u003cli\u003eImproved power and torque throughout the entire RPM band\u003c\/li\u003e\n\u003cli\u003eWeighs 40 lbs versus 55.1 lbs for the factory system\u003c\/li\u003e\n\u003cli\u003eBMW factory style hardware — no cutting or re-welding required\u003c\/li\u003e\n\u003cli\u003eComplete illustrated instruction manual supplied\u003c\/li\u003e\n\u003cli\u003eTwo year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eActive Autowerke rear mufflers, left and right\u003c\/li\u003e\n\u003cli\u003eCenter exhaust bracket\u003c\/li\u003e\n\u003cli\u003eExhaust hangers, left and right\u003c\/li\u003e\n\u003cli\u003eRed rubber hanger assemblies\u003c\/li\u003e\n\u003cli\u003eExhaust clamps\u003c\/li\u003e\n\u003cli\u003e8mm Allen bolt for tip extension adjustment\u003c\/li\u003e\n\u003cli\u003e20mm aluminum bushing for the E93 convertible\u003c\/li\u003e\n\u003cli\u003eComplete illustrated instruction manual\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 exhaust — it uses BMW factory style hardware and bolts straight on.\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-11-015-11-016-e9x-m3-rear-exhaust-installation-instructions.pdf?v=1787172586\"\u003eActive Autowerke Signature Rear Exhaust installation instructions — BMW E90 \/ E92 M3, including the additional steps for the E93 convertible (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.youtube.com\/watch?v=F-pSqbWkwKQ\" target=\"_blank\" rel=\"noopener\"\u003eActive Autowerke E9X M3 Signature Rear Exhaust installation video (YouTube)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable class=\"va-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3 Convertible\u003c\/td\u003e\n\u003ctd\u003eE93\u003c\/td\u003e\n\u003ctd\u003eS65 4.0L V8\u003c\/td\u003e\n\u003ctd\u003e2008–2013\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":42888440021158,"sku":"11-016","price":1519.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/products\/IMG_5014small_2048x__85465.1616464513.jpg?v=1654633992"},{"product_id":"active-autowerke-gesi-ultra-high-flow-cats-upgrade-for-signature-x-pipe-fitting-bmw-e9x-m3","title":"Active Autowerke GESI Ultra High Flow Cats Upgrade – BMW M3 (E9x)","description":"\u003cdiv class=\"sl-desc\"\u003e\n\u003ch2\u003eOVERVIEW\u003c\/h2\u003e\n\u003cp\u003eActive Autowerke's GESI G-Sport cats upgrade is a set of connecting pipes for their Signature Track Pipe with X-Pipe on the BMW E9X M3, for the owner who already runs that pipe and wants to clear the check engine light without resorting to a tune while still meeting emissions requirements as specified by the EPA.

longer.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConstructed from 100% 304 brushed stainless steel\u003c\/li\u003e\n\u003cli\u003eSingle-pipe design that
