PRODUCT DESCRIPTION
Darktrace BMW M3/M4 G80/G81/G82/G83 4” Fatboi Midpipe
Upgrade your BMW M3/M4 G80/G81/G82/G83 with the Darktrace 4” Fatboi Midpipe, engineered for maximum airflow, deeper sound, and increased performance. Designed for enthusiasts who want a more aggressive exhaust character and improved turbo response, this midpipe transforms both the sound and feel of the S58 platform.
Constructed from premium 304 stainless steel, the Darktrace Fatboi Midpipe features an oversized 4-inch design that significantly improves exhaust flow and reduces restriction compared to the factory setup. The larger diameter piping allows exhaust gases to exit more efficiently, helping the engine breathe better while enhancing turbo spool and overall responsiveness.
The Fatboi configuration delivers a noticeably deeper, louder, and more aggressive exhaust tone with increased presence throughout the RPM range. Expect enhanced turbo acoustics, sharper crackles, and a more raw motorsport-inspired sound, while still maintaining a refined driving experience during cruising.
Designed as a direct-fit upgrade for the factory exhaust system, the Darktrace 4” Fatboi Midpipe installs seamlessly with OEM mounting points and requires no unnecessary modifications. Precision engineering ensures excellent fitment and long-term reliability.
With reduced backpressure and optimized flow characteristics, drivers can expect improved throttle response, smoother power delivery, and noticeable gains in performance. Whether you’re building a street car or track-focused setup, the Fatboi Midpipe delivers the sound and performance to match.
Features:
- Oversized 4-inch midpipe design for maximum exhaust flow
- Approximately 5kg lighter than the OEM midpipe, improving vehicle dynamics
- Deeper and more aggressive exhaust note with enhanced turbo sound
- Reduced backpressure for improved throttle response and performance
- Smooth mandrel-bent construction for optimized airflow
