For the BMW owner seeking increased performance without the drawbacks of a "catless" system, the Active Autowerke Aflow Catted Downpipes offer the perfect solution. These downpipes feature high-flow metallic catalytic converters that are specifically designed to maintain exhaust efficiency while preventing the dreaded Check Engine Light (CEL). Unlike track-only pipes that can produce raw fuel odors and cabin drone, the Aflow series maintains a sophisticated, refined exhaust note suitable for a luxury daily driver. Each set is custom-made in-house to ensure an exact bolt-on fit, providing a reliable solution that satisfies both the driver’s demand for power and the vehicle’s onboard diagnostic requirements. Key Features: No CEL Guarantee: Advanced Aflow catalyst technology prevents catalytic efficiency dashboard warnings. Refined Exhaust Note: Provides an aggressive V8 growl while maintaining cabin comfort for daily use. Bolt-On Installation: No cutting or welding required; replaces the bulky factory units directly. Thermal Resilience: Built to withstand the high temperatures generated by the S63 and N63 twin-turbo engines. Safe for Occupants: Reduces harmful emissions and raw exhaust odors compared to catless alternatives. Specifications: Primary Material: Brushed 304 Stainless Steel Fitting: Direct OEM Replacement (Bolt-on) Manufacturing Location: Hand-made in Miami, FL Weight Reduction: Lighter than the heavy, ceramic-core factory catalytic converters Surface Finish: Natural Stainless Lead Time: Custom made-to-order (Approx. 2 weeks)
