Fi Exhaust Valvetronic Catback Exhaust System for BMW 840i Gran Coupe (G16) 2019+
The Fi Exhaust Valvetronic Catback Exhaust System for the BMW 840i Gran Coupe (G16) is designed for drivers who want direct control over exhaust flow, sound, and overall performance. This system uses advanced valve technology that lets you switch between a quiet, refined tone and a more aggressive exhaust note at the push of a button.
Pair this system with a catless setup and high-flow downpipes, and you can see measurable gains in horsepower and torque, typically in the 5-10% range. This upgrade improves throttle response and delivers a more responsive driving experience across the entire rev range. With the valves closed, exhaust gases are routed through the muffler for a low-volume tone that works well for daily driving. Open the valves, and the system produces a deeper, more pronounced exhaust sound that highlights the turbocharged B58 inline-six engine.
Each system is built with precision-tuned muffler internals developed specifically for the 840i Gran Coupe. You get a balanced result that combines improved performance, comfortable cruising, and a more engaging exhaust tone that fits the character of the vehicle.
Key features and benefits:
- Direct bolt-on installation with no cutting required
- T304 stainless steel construction for long-term durability
- Improved exhaust flow for better throttle response
- Refined tone with valves closed, aggressive sound with valves open
- Designed specifically for BMW 840i Gran Coupe (G16)
Catback Exhaust:
- This system feature integrated valvetronic technology designed to give drivers control over exhaust sound while supporting engine performance across the full RPM range. With the ability to adjust valve positions, this system helps manage exhaust flow efficiently, improving responsiveness during acceleration and maintaining consistent power delivery at both low and high engine speeds.
- Before valvetronic exhaust systems were developed, exhaust design often required a compromise between low-end torque and high-end horsepower. FI EXHAUST addresses this limitation by allowing vehicles to perform effectively in different driving conditions. Drivers can experience smooth power at lower RPMs and sustained output as revs increase, making this technology a practical upgrade for both street driving and performance-focused builds.
Downpipe (Optional):
- Race Downpipe
- Sport 200Cell Downpipe
- This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only
- Race Downpipe may trigger a check engine light due to removal of factory catalytic converters
- This product is for “off-road use only”– check your local laws & regulations regarding the modification of the exhaust system by checking the vehicle code for your state. Many states are stringent on exhaust modification laws to pass SMOG.
Fi Exhaust Pro Control (Optional):
- The Fi Exhaust Pro Control System gives you full command over your valvetronic exhaust setup through a smart control box, dual-button remote, and a dedicated mobile app. Built for drivers who want quick access and consistent performance, this system integrates directly with your vehicle to manage exhaust valve behavior in real time.
- The mobile app includes a built-in diagnostic feature that can scan for and clear check engine lights at startup, either manually or through automatic detection. You can also view live valve position data through a simple interface, making it easy to track how your exhaust system is operating while you drive.
- With Auto Mode, you can set specific parameters based on RPM, vehicle speed, and turbo boost. Once configured, the system adjusts valve operation on its own to match driving conditions. This helps maintain the balance between sound control and performance without constant input.
- The included remote control allows you to assign functions to each button, giving you direct access to open or close the valves or switch into Auto Mode. This setup puts full control in your hands, whether you are driving daily or pushing the car harder when conditions allow.
