BMW 4-Series F83 Active Exhaust – Valvetronic Performance Exhaust Systems

BMW 4-Series F83 Active Exhaust – Unleash the Sound of Your M4 Convertible

The BMW 4-Series F83 M4 Convertible, produced from 2014 to 2020, combines open-top driving pleasure with exceptional performance. Powered by the S55 3.0L twin-turbo inline-six engine, the F83 delivers an exhilarating experience — but the stock exhaust system often fails to match the car’s dynamic personality. Designed to meet emissions and noise regulations, the OEM exhaust limits both sound and performance. Upgrading to a BMW F83 active exhaust system with valvetronic technology unlocks the car’s true character, giving you full control over its exhaust tone and driving dynamics.

Why Upgrade to a BMW F83 Active Exhaust?

The factory exhaust on the F83 M4 Convertible prioritizes refinement over passion, which can leave enthusiasts wanting more. A performance active exhaust system provides multiple benefits:

• Valvetronic sound control – instantly switch between a quiet, refined tone and an aggressive, motorsport-inspired roar.
• Dual driving personality – valves closed for comfortable city driving; valves open for thrilling top-down performance.
• Enhanced performance – optimized exhaust flow reduces backpressure, improving turbo efficiency and throttle response.
• OEM integration – fully compatible with BMW’s factory driving modes and electronics.
• Tuning-ready design – supports Stage 1, Stage 2, hybrid turbo builds, and ECU remapping.
