Active Autowerke BMW S58 G80 M3 G82 M4 G87 M2 Downpipes W Aflow CATs

For the owner of a flagship G-series M-car, Active Autowerke provides a "no-compromise" performance upgrade that prioritizes both power and daily-driver refinement. These downpipes feature integrated GESI G-Sport catalytic converters, which are EPA-registered and fully OBD2 compliant. Utilizing proprietary precious metal loading, these converters reach operational efficiency within just 9 seconds of startup, drastically reducing emissions and eliminating the pungent exhaust smells common with aftermarket pipes. Designed as a direct bolt-on replacement, this system preserves your car's sophisticated electronics while providing a deep, aggressive V8-like growl that the S58 engine was always meant to have. Key Features: Refined Exhaust Note: Increases the volume and depth of the exhaust tone while maintaining a drone-free cabin. Fast Catalyst Light-Off: Proprietary loading technology ensures emissions systems satisfy factory monitors quickly. Corrosion Resistance: High-grade T304 stainless steel substrate is furnace-braised to the mantle for outstanding durability. Precision Casting: Casted upper flanges provide superior strength compared to standard cut-and-weld alternatives. Warranty Protected: Covered by a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Specifications: System Type: Twin Catted Downpipes Weight Reduction: Significantly lighter than the heavy ceramic factory assemblies Flow Rating: Engineered for engines producing up to 850 HP Hardware: Includes lower mounting brackets and precision V-bands Manufacturing: Hand-fabricated in the USA Vehicle Fitment: * 2021+ BMW M3 Sedan (G80) / Competition / xDrive 2021+ BMW M4 Coupe (G82) / Competition / xDrive 2023+ BMW M2 (G87) *Important Note: The catalyst warranty is void if the vehicle is equipped with an "aggressive burble" tune, as excessive backfire can physically degrade the catalyst core over time.
