This BMW M5 F90 Performance Downpipe (2017–2021) is engineered specifically for the 4.4T Twin-Turbo V8 (S63) engine, focusing on maximum exhaust flow, structural stability, and long-term durability.
Designed as a direct replacement for the factory downpipe, it eliminates restrictive airflow and unlocks the full performance potential of the S63 platform used in 2017–2021 BMW M5 F90 models.
The factory downpipe on the BMW M5 F90 (2017–2021) is designed primarily for emissions and noise compliance, which creates unnecessary exhaust back pressure—especially on tuned S63 engines.
Upgrading to a high-flow performance downpipe is one of the most effective modifications for improving turbo response, power delivery, and exhaust sound on 2017–2021 BMW M5 F90 vehicles.
