11MODE BMW i8 (I12 / I15) Exhaust Controller

NEW V2 – NOW WITH MEMORY FUNCTION

Unlock the unique exhaust sound of your BMW i8 with the 11MODE V2 Exhaust Controller. Designed for I12 Coupe and I15 Roadster models equipped with factory-controlled valved exhaust systems, this controller allows you to take full control of your exhaust valves and enhance the driving experience.

Many drivers assume that Sport or Performance driving modes automatically keep the exhaust valve fully open. In reality, the factory ECU continues to manage valve operation and may partially or fully close the valve depending on driving conditions, speed, and system load. The 11MODE Exhaust Controller overrides this factory logic, giving you direct control over the exhaust valve and unlocking a more consistent exhaust tone.

The latest V2 version includes a Memory Function that automatically remembers the last selected setting for improved convenience.
