Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F90 M5 Collection, these S63TU downpipes represents our outlook on creating innovative products with performance in mind.\u003c\/p\u003e\u003cp\u003eThe S63TU downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory M5 downpipes therefore reducing radiant heat and increasing performance. Our M5 downpipes will significantly increase horsepower and torque throughout the powerband. They will reduce any turbo lag\u003c\/p\u003e\u003cp\u003eOur F90 M5 downpipes are manufactured in house using 304 stainless steel. Each set is meticulously tig welded and checked for perfect fitment. Our design uses a factory matched 3.5\" v-band inlet that tapers to a high flowing, mandrel bent\" body and includes the lower section sold by others as a \"mid-pipe\".\u003c\/p\u003e\u003cp\u003eOur downpipes allow the use of the OEM O2 sensor heat shield. With the heat shield installed the engine bay remains stock-looking for a sleeper look!\u003c\/p\u003e\u003cp\u003eThis variant includes a pair of 4.5\" high flow Active A-Flow catalytic converters that will NOT produce a CEL for cat efficiency!\u003c\/p\u003e\u003cp\u003eThe Active A-Flow Extra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. Active A-Flow Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. Active proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most \"Check Engine Lights\" for cat efficiency errors. These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.\u003c\/p\u003e\u003cp\u003eThe Active A-Flow Catalytic Converters are rated for engines putting out up to 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Federal law prohibits the tampering of an emissions control device. Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren't adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet the standards set by the EPA, not CARB.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNO CEL for catalytic efficiency when using this downpipe\u003c\/li\u003e\n\u003cli\u003eActive EPA registered high flow and fully OBD2 compliant\u003c\/li\u003e\n\u003cli\u003eCasted upper stainless steel V-Band for precise fitment\u003c\/li\u003e\n\u003cli\u003e4.50\" diameter piping allows for maximum power output\u003c\/li\u003e\n\u003cli\u003eQuicker turbo spool\u003c\/li\u003e\n\u003cli\u003eRated for up to 850 hp applications\u003c\/li\u003e\n\u003cli\u003eWithstands up to 1500 F\u003c\/li\u003e\n\u003cli\u003eCan reach operational efficiency within 9 seconds of startup\u003c\/li\u003e\n\u003cli\u003eEasily bolts-on no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eAccepts OEM O2 sensor heat shield\u003c\/li\u003e\n\u003cli\u003eDurable construction from TIG welded 304 stainless steel\u003c\/li\u003e\n\u003cli\u003ePrecise fitment\u003c\/li\u003e\n\u003cli\u003eUltra high flow 400 cell per square inch catalyst\u003c\/li\u003e\n\u003cli\u003eEPA compliant for use on OBD2 vehicles (1996 and newer) except in California\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e304 stainless steel substrate is furnace braised to the mantle for outstanding durability\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eActive proprietary precious metal loading technology ensures greatly reduced emissions\u003c\/li\u003e\n\u003cli\u003eIdeal for Forced Induction Applications with no loss of HP\u003c\/li\u003e\n\u003cli\u003eBoth passengers and drivers are safe from harmful emissions and noise\u003c\/li\u003e\n\u003cli\u003eCovered by 5 Year \/ 50,000 Mile Warranty (on shell and tube ends) and 2 year \/ 25,000 Mile Warranty on the Catalytic core to original purchaser only - NOTE: warranty will be null and void if your car has excessive burble (greater than stock) as that physically destroys the catalytic core\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Active AutoWerke","offers":[{"title":"Default Title","offer_id":42714006126679,"sku":"11-063A","price":2279.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/8642\/1591\/files\/e42114fd-0f88-4de5-a708-cec0ca4788eb.jpg?v=1776705144","url":"https:\/\/jmautosports.com\/products\/active-autowerke-f90-m5m8-x5mx6m-active-aflow-catted-downpipes-11063a","provider":"JM Auto Racing","version":"1.0","type":"link"}
