Early prototypes ran without flex joints and created an annoying vibration inside the cabin, so the finished design adds them. Made from 1.3 to 1.5 mm thick 304 stainless steel and developed for precise fitment on both the F80 M3 and F82 M4, the difference in performance is noticeable the moment you leave your driveway.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e10–15 HP increase, measured when paired with the Active Autowerke F8X mid pipe\u003c\/li\u003e\n\u003cli\u003e1.3–1.5 mm thick 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eFlex joints to dampen cabin vibration\u003c\/li\u003e\n\u003cli\u003eLighter weight than the factory downpipes\u003c\/li\u003e\n\u003cli\u003eLess restrictive and more free flowing, for quicker turbo response\u003c\/li\u003e\n\u003cli\u003eImproved low-end and mid-range performance\u003c\/li\u003e\n\u003cli\u003eBrushed stainless finish\u003c\/li\u003e\n\u003cli\u003eOptional White Lightning exhaust coating by Swain Tech Coatings, available at additional charge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eComplete downpipe set as supplied by Active Autowerke; see the installation instructions for the full bill of materials.\u003c\/li\u003e\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 downpipe set.\u003c\/li\u003e\n\u003cli\u003eOptional: \u003ca href=\"\/products\/active-autowerke-mid-pipe-for-bmw-m3-m4-f80-f82\"\u003eActive Autowerke Mid Pipe for BMW M3 \u0026amp; M4 (F80 \/ F82)\u003c\/a\u003e — the quoted 10–15 HP gain is measured with this mid pipe fitted.\u003c\/li\u003e\n\u003cli\u003eInstaller supplies basic hand tools and a lift or jack stands.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eActive Autowerke does not publish a downloadable installation manual for this downpipe set in its instruction library.

Active Autowerke's 4.5 inch pipe uses the fewest bends possible, tapering to 3.5 inch at a stainless flex joint and then to 80 mm to meet the OEM exhaust — never dropping below the stock 80 mm — so back pressure is kept to a minimum while daily drivability is retained. This variant carries a 4.5 inch GESi G-Sport Ultra High Output catalytic converter, built in full 304 stainless including the substrate, that keeps emissions low at high flow and will not trigger a check engine light.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4.50 inch diameter piping, tapering to 3.5 inch and then to 80 mm at the OEM exhaust connection\u003c\/li\u003e\n\u003cli\u003eDiameter is never reduced below the stock 80 mm\u003c\/li\u003e\n\u003cli\u003e1.5 mm wall thickness\u003c\/li\u003e\n\u003cli\u003e4.5 inch ultra high flow GESi G-Sport catalytic converter, 400 cells per square inch\u003c\/li\u003e\n\u003cli\u003eRated for 500 to 850 hp applications\u003c\/li\u003e\n\u003cli\u003eTIG welded 304 stainless steel construction throughout\u003c\/li\u003e\n\u003cli\u003e304 stainless steel catalyst substrate, furnace brazed to the mantle for durability\u003c\/li\u003e\n\u003cli\u003eCast upper stainless steel V-band for precise fitment\u003c\/li\u003e\n\u003cli\u003eStainless flex joint\u003c\/li\u003e\n\u003cli\u003eWithstands temperatures up to 1500 F\u003c\/li\u003e\n\u003cli\u003eReaches operational efficiency within 9 seconds of startup\u003c\/li\u003e\n\u003cli\u003eEPA registered, fully OBD2 compliant for 1996 and newer vehicles, except in California\u003c\/li\u003e\n\u003cli\u003eSuited to forced induction applications with no loss of horsepower\u003c\/li\u003e\n\u003cli\u003eBolts on with no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003cli\u003eCovered by a 5 year \/ 50,000 mile warranty on the catalytic converter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eComplete downpipe assembly as supplied by Active Autowerke; see the installation instructions for the full bill of materials.\u003c\/li\u003e\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 downpipe; it bolts on with no cutting or welding required.\u003c\/li\u003e\n\u003cli\u003eOptional: Active Autowerke offers this downpipe in a version supplied with a turbo flange gasket.
