Active Autowerke Downpipes W Active A-flow Cats - F10/F12 M5/M6 11-093A

Downpipes W Active A-flow Cats - F10/F12 M5/M6

Efficiency in a forced-induction engine is determined by the pressure differential across the turbine wheel. Active Autowerke's Aflow Catted Downpipes maximize this differential by utilizing a streamlined, low-restriction design. Each set is hand-made from premium 304 stainless steel and features furnace-braised substrates for maximum longevity under the extreme temperatures of the "hot-V" turbo configuration. The integrated 400-cell catalytic converters reach operational efficiency within just 9 seconds of startup, ensuring the system meets modern OBD2 requirements while supporting up to 800 HP without a loss in performance. Key Features: Precision Fitment: Each unit is meticulously TIG-welded and checked against master jigs to guarantee a perfect bolt-on installation with no cutting or welding. EPA Compliant: 49-state EPA registered and fully OBD2 compliant (Excludes California). Thermal Management: Engineered to reduce radiant heat in the engine bay compared to restrictive factory units. High-Flow Catalyst Substrate: 304 stainless steel substrate furnace-braised to the mantle for outstanding vibration and heat resistance. Comprehensive Protection: Covered by a 5-year/50,000-mile structural warranty and a 2-year core warranty. Specifications: Inlet Type: Precision-casted 3.5" Stainless Steel V-Band Outlet Diameter: 3.0" Mandrel-Bent Tubing Catalyst Matrix: 400 Cells Per Square Inch Operating Temperature: Tested to withstand up to 1,500°F Vehicle Fitment: * 2011–2016 BMW M5 (F10) 2012–2018 BMW M6 Coupe / Convertible / Gran Coupe (F12/F13/F06) Custom Build Time: Typically made-to-order (Approx. 2-week lead time)
