Downpipe W Active A-flow Cat - F3x/F87 M2

Product Details

Active Autowerke’s Aflow Catted Downpipe offers the perfect balance for the BMW owner who demands high performance but requires daily-driver refinement. Unlike track-only "straight pipes," the Aflow system utilizes a sophisticated metallic substrate catalytic converter that significantly reduces harmful emissions and raw fuel odors. This allows you to enjoy the power of a high-flow exhaust while maintaining a clean cabin environment and remaining OBD2 compliant. Each unit is custom-made in Miami and features cast upper flanges to ensure a factory-perfect, leak-free seal every time.

Key Features:

• Clean Performance: High-flow catalyst virtually eliminates the raw fuel smell associated with aftermarket downpipes.

• Precision Engineering: Features a casted stainless steel upper V-band for a surgical fit against the turbo housing.

• OBD2 Compliance: Engineered to satisfy factory emissions monitors, keeping the dash clear of "Efficiency" codes.

• Refined Acoustics: Increases the exhaust volume under wide-open throttle while remaining quiet and sophisticated during highway cruising.

• Heat Management: Designed to withstand the intense thermal cycles of a high-output turbocharged engine.
