Alpina B8/G16 M850i Valved Sport Exhaust System

This exhaust system was developed for the BMW G16 M850i Gran Coupé and the Alpina B8. The complete system builds straight onto the factory downpipes, or you combine it with the free flow race front pipes. Valve control follows the factory Sport and Sport+ modes, so you set the sound from the driver's seat, and across the whole rev range the car sounds fuller than it does with the factory system.

Sound and control

• Valves closed: a controlled tone for daily driving.
• Valves open: deeper and more aggressive, with more volume and character.
• OEM integration: control through Sport and Sport+, without an extra remote or wiring.

Performance and construction

• T304 stainless steel, durable and corrosion resistant
• 7.1 kg lighter than the factory exhaust
• Fully mandrel bent tubing for maximum flow
• TIG welds for strength and a tight finish
• Reuses the factory exhaust tips, for a factory look

Features
