G87 M2 Valved Rear Axle-back Exhaust (Matte Black Tips)
Active Autowerke’s G8X Valved Rear Exhaust section is the result of over 40 years of BMW-specific R&D. While the primary goal is a superior sound signature, the engineering team focused heavily on optimum exhaust flow and weight reduction. By replacing the dense factory muffler assembly with a streamlined stainless steel unit, this exhaust reduces weight hanging off the rear of the car while maximizing exhaust gas scavenging. The internal geometry is designed to provide a smooth transition of gases, which is critical for maintaining turbocharger efficiency on high-horsepower builds.
Key Features:
OEM+ Integration: Reuses the stock BMW valve actuators, meaning no extra wiring, controllers, or dash errors.
Resonance Control: Internal muffler chambers are tuned to eliminate cabin drone while allowing the S58 character to shine under load.
Industrial Durability: Full 304 Stainless Steel construction ensures maximum resistance to heat cycles and corrosion.
Fitment Guaranteed: Every exhaust is test-fitted on an in-house G8X fixture as part of a rigorous quality control measure.
Specifications & Tip Options:
Configuration: Valved Axle-back (Connects to factory or aftermarket mid-pipes)
Installation: Bolt-on design; includes all necessary heavy-duty clamps and hardware
Available Tip Styles:
Brushed Stainless Steel
Matte Black Coated
