Each time you remove your exhaust manifold, the gaskets need replaced. If you attempt to reuse them, they can leak and fail, causing noise and exhaust heat to fill your engine compartment. Pick up some new nuts and anti-seize to make the replacement job easier. Quantity of four required for re-installation.

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)
