11-041A - Active Autowerke S63 N63 A-Flow Catted Downpipes
Active Autowerke S63 N63 A-Flow Catted Downpipes
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)
