The Speed Logic race catless downpipe removes the restriction built into the OEM downpipe so the turbo spools faster and makes more power, and it gives the car a deeper, louder exhaust note along with the turbo sounds the factory system muffles. Depending on tuning, supporting modifications and fueling, the gain runs from roughly 20 to 25 horsepower. Every Speed Logic downpipe is built from 304 stainless, 100% TIG welded with all welds backpurged in argon, and carries a lifetime warranty.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4\" stainless steel race catless downpipe\u003c\/li\u003e\n\u003cli\u003eFull 304 grade stainless steel construction\u003c\/li\u003e\n\u003cli\u003eAdds 20-25+ horsepower and 25-30+ lb-ft of torque with adequate tuning\u003c\/li\u003e\n\u003cli\u003eRemoves the restriction built into the factory exhaust system\u003c\/li\u003e\n\u003cli\u003eDelivers turbo sounds and a deeper exhaust note\u003c\/li\u003e\n\u003cli\u003e100% TIG welded\u003c\/li\u003e\n\u003cli\u003eAll welds fully backpurged with 100% argon\u003c\/li\u003e\n\u003cli\u003eWelds are not ground or polished\u003c\/li\u003e\n\u003cli\u003eCatless - off-road use only, not available for sale in California or other emissions-testing states\u003c\/li\u003e\n\u003cli\u003eIncludes a Speed Logic LIFETIME warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eComplete downpipe as supplied by Speed Logic.

It does not fit the N26 engine.\u003c\/p\u003e\n\u003cp\u003eRestrictions in the exhaust system rob horsepower and torque, especially on turbocharged cars, so removing as much restriction as possible increases both significantly. The factory catalytic converter inside the stock downpipe is a major culprit: its catalyst material is formed into tight honeycomb weaves that exhaust gas must pass through, and it creates turbulence downstream that slows exhaust flow further. The factory catalyzer uses a 400 cell ceramic core, meaning 400 cells per square inch. Evolution Racewerks uses a 200 cell metallic core instead — fewer, larger cells that exhaust gas passes through more easily. Lower cell count means higher flow, which means more power, faster turbo spool and better throttle response. A metallic core also tolerates more heat, lasts longer and weighs less than the ceramic factory unit.\u003c\/p\u003e\n\u003cp\u003eThe downpipe is constructed from 100% 304 grade stainless steel with mandrel bent piping, 100% TIG welded by ER's in-house fabricators and built in the USA. The factory turbine housing uses a 4\" V-band flange, which ER duplicated and CNC machined from billet 304 stainless. Because the ER catalytic converter is more compact than the factory unit, there is room for very long transitions between the 4\" turbo outlet and the 2.5\" exhaust rather than the short transitions BMW was forced to use, which reduces turbulence and backpressure. Like the factory part, the ER downpipe incorporates a 100% stainless steel flex section so the exhaust can move without putting undue stress on the turbocharger, manifold and exhaust components — something many competitors leave out.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCatalytic converter: high flow 200 cell metallic core\u003c\/li\u003e\n\u003cli\u003ePiping: mandrel bent 4\", with long transitions down to the 2.5\" factory exhaust diameter\u003c\/li\u003e\n\u003cli\u003eConstruction: 100% 304 grade stainless steel, 100% TIG welded, built in the USA\u003c\/li\u003e\n\u003cli\u003eTurbocharger flange: precision CNC machined 4\" V-band cut from billet 304 stainless steel\u003c\/li\u003e\n\u003cli\u003e100% stainless steel flex section, as used on the factory downpipe, for proper exhaust movement\u003c\/li\u003e\n\u003cli\u003eO2 sensor retained in the factory location; CNC machined O2 bung and laser cut brackets TIG welded with stainless rod\u003c\/li\u003e\n\u003cli\u003eFinish: mirror polish or brushed\u003c\/li\u003e\n\u003cli\u003eOptional high temperature black thermal (ceramic) coating rated to 2000°F; available in black only\u003c\/li\u003e\n\u003cli\u003eOptional additional O2 sensor bung for a wideband O2 sensor, supplied with a pre-installed plug\u003c\/li\u003e\n\u003cli\u003eOptional EGT sensor bung for EGT gauges, supplied with a pre-installed plug\u003c\/li\u003e\n\u003cli\u003eCompatible with the factory or aftermarket exhaust systems\u003c\/li\u003e\n\u003cli\u003eTrack tested durability\u003c\/li\u003e\n\u003cli\u003eAll hardware for a complete installation is included\u003c\/li\u003e\n\u003cli\u003eWarranty: Evolution Racewerks Limited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSports Series 4\" high flow 200 cell metallic catted downpipe\u003c\/li\u003e\n\u003cli\u003eAll hardware required for complete installation, as supplied by Evolution Racewerks\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 Evolution Racewerks specifies no additional hardware for this part; all installation hardware is supplied and the downpipe works with the factory or an aftermarket exhaust.\u003c\/li\u003e\n\u003cli\u003eA signed Vehicle Compliance Waiver and vehicle use verification are required before this part can be sold and shipped.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEvolution Racewerks does not publish a downloadable installation guide for this downpipe.

It does not fit the N20 engine.\u003c\/p\u003e\n\u003cp\u003eThe factory catalyzer uses a 400 cell ceramic core, meaning exhaust gas must pass through 400 cells per square inch. Evolution Racewerks uses a 200 cell metallic core: fewer cells per square inch means each cell is larger and exhaust passes through more easily, so flow goes up. Higher flow means more power, faster turbo spool and better throttle response. A metallic core also handles more heat, lasts longer and weighs less than the ceramic factory unit. Because exhaust restriction robs horsepower and torque on turbocharged cars, replacing the restrictive factory downpipe and converter unlocks meaningful power.\u003c\/p\u003e\n\u003cp\u003eThe downpipe is built from 100% 304 grade stainless steel with mandrel bent piping, 100% TIG welded in house and made in the USA. The 4\" turbocharger V-band flange is CNC machined from billet 304 stainless steel, and the O2 sensor stays in the factory location. The headline feature of the N26 version is its CNC machined solid stainless steel billet ball joint. BMW press-forms its ball joint, which mirrors the shape on the inside of the pipe, so exhaust dives into the valley and back out again and creates significant turbulence right at that point — turbulence that slows exhaust velocity and raises backpressure. ER machined the ball joint from solid billet instead, keeping the factory connection while leaving the interior smooth so exhaust flows through unrestricted. ER's in-house testing showed real world improvements from the billet joint, which is why the N26 downpipe costs more than the N20 version, where a simpler slip-fit design is used.\u003c\/p\u003e\n\u003cp\u003eLike the factory downpipe, the ER piece incorporates a 100% stainless steel flex section so the exhaust system can move without loading the turbocharger, exhaust manifold and other components.

The GESi catalytic converter will produce emissions that meet the standards set by the EPA, not CARB.\u003c\/li\u003e\n\u003cli\u003eImportant: this downpipe fits N20 cars only. It will not fit the N26 (SULEV \/ California-emissions) version of the same engine — check your engine code before ordering. These cars were built with either the N20 or the N26, so Active Autowerke asks that you supply your VIN so the correct engine can be verified. Fitment applies to US-model cars only. Confirm fitment with Speed Logic before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003e11-079\u003c\/strong\u003e — listed by Active Autowerke as 11-079 KIT\u003c\/li\u003e\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\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e228i\u003c\/td\u003e\n\u003ctd\u003eF22 \/ F23\u003c\/td\u003e\n\u003ctd\u003eN20 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2014–2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e328i\u003c\/td\u003e\n\u003ctd\u003eF30 \/ F31 \/ F34\u003c\/td\u003e\n\u003ctd\u003eN20 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2012–2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e428i\u003c\/td\u003e\n\u003ctd\u003eF32 \/ F33 \/ F36\u003c\/td\u003e\n\u003ctd\u003eN20 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2014–2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Active Autowerke","offers":[{"title":"Default Title","offer_id":42114055340198,"sku":"11-079","price":1424.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/products\/N20cata_2048x_71e6abe9-429e-47da-b95f-3926b187bef8.jpg?v=1642709751"}],"url":"https:\/\/speedlogicauto.com\/collections\/bmw-428i-f33-downpipes.oembed","provider":"SPEED LOGIC","version":"1.0","type":"link"}
