F90 M5 Valve Controller – BMW M5/M5 Competition Exhaust Control by ExValve ASR Unlock True Sound Freedom in Your Twin-Turbo V8 M5 While the BMW F90 M5 and M5 Competition offer serious performance and iconic exhaust notes, they still rely on ECU-controlled exhaust valves that don’t always match your driving style. With the F90 M5 Valve Controller by ExValve (ASR), you can finally take full manual control of your car’s exhaust system — whether you want quiet starts, full-throttle sound, or something in between. Because of its smart, plug-and-play design, this module makes exhaust customization simple and safe. Engineered for BMW F90 M5 and M5 Competition (2017–2023) This ExValve controller was designed specifically for the BMW M5 (F90 platform), including both base and Competition models with the S63 engine. It connects directly to the factory exhaust valve motors with OEM-grade T-harnesses, so you don’t have to cut or splice wires. Compatible With: BMW F90 M5 (2017–2023) BMW M5 Competition (F90) Stock or aftermarket valved exhaust systems Vehicles with S63 4.4L twin-turbo V8 engines Need more upgrades?

Take Control with Three Simple Valve Modes With the included RF remote fob, you can toggle between three modes to suit your driving environment: Open Mode: Valves remain fully open for maximum aggression Close Mode: Valves stay shut for a discreet, quiet ride Auto Mode: Valves behave based on factory ECU logic Whether you're sneaking out of the garage at 6 AM or heading to a track day, you’re always in command — with no tools, apps, or menus required. Quick and Reversible Plug-and-Play Install Unlike many DIY exhaust modules that require software coding or permanent wiring changes, the ExValve controller installs using plug-and-play OEM connectors. That means installation is quick, tool-light, and 100% reversible. Installation Overview: Lift the vehicle and locate factory exhaust valve connectors Disconnect the plugs and insert ExValve T-harness inline Secure the controller box in a dry area using adhesive or zip ties Test valve response using the RF remote Enjoy full control with zero CELs or errors Because it mimics stock signals, the controller won’t interfere with your M5’s electronics, drive modes, or ECU tuning. CEL-Free and OEM-Safe ExValve is engineered to ensure no check engine lights (CELs), fault codes, or system conflicts. It safely simulates OEM valve behavior using CAN-safe logic and built-in resistors. Additional Safety Benefits: Works with all ECU software versions Does not interfere with OBD2 diagnostics Maintains factory drive modes (Comfort, Sport, Sport+) Ideal for leased or warranty-covered vehicles This makes it the smart upgrade for owners who want flexibility without compromise. Compatible With Aftermarket Valved Exhaust Systems If you’ve upgraded your F90 M5 exhaust, chances are it retains OEM-style valve motors. Fortunately, this ExValve module works perfectly with top brands, including: Akrapovič Evolution Exhaust for BMW M5 Remus Sport Exhaust System for M5 IPE Innotech Exhaust for F90 M5 So whether you're running stock or modified, this controller will give you full control over your sound profile. Compact Wireless Remote – Simple and Effective The supplied RF remote fob features dedicated buttons for each mode, with haptic feedback and a fast response time. Unlike app-based controllers that require Bluetooth pairing, this fob operates independently and functions even with the engine off. Mount it on your keychain, in your glovebox, or keep it tucked beside the center console — you'll always have quick access to your desired sound mode. Built to Last – Premium Construction for Demanding Environments Because the F90 M5 generates extreme underbody heat, the ExValve controller is built with automotive-grade materials that can handle the environment. All components are weather-resistant and vibration-proof, ensuring long-term durability. Built for: High-temp exhaust proximity Road grime and splash zones Continuous high-RPM use Aggressive daily driving Whether you're in hot climates or track conditions, ExValve is ready to perform. Why Enthusiasts Trust ExValve by ASR Cheap modules may offer similar features, but they often fall short in reliability, support, and safety. ExValve is trusted by tuners, shops, and M owners alike for its flawless integration and performance. Why It’s Better: Fully plug-and-play 3 valve control modes Works with factory and performance exhausts Zero dashboard errors Built and tested to OEM standards Complete your build with a Carbon Fibre Rear Diffuser for M5 F90 or F90 M5 Dry Carbon Front Lip for a matched OEM+ look.
