Deep Tone Industries BMW G90 & G99 M5 S68 Exhaust Midpipe (2024+)

The DeepTone mid pipe for the BMW G90 and G99 M5 focuses on the part of the exhaust system that defines how the car sounds and responds. Designed specifically for the 4.4-litre twin-turbo V8, this mid section uses a proven V8 flow layout that improves exhaust gas balance while preserving the refinement expected of BMW’s latest M5 generation.

By refining the mid section rather than replacing the entire system, this upgrade delivers a deeper, more controlled tone with improved flow consistency under load. At cruising speeds, the sound remains composed and settled; when pushed, the system opens up with greater depth and character rather than raw volume. The result is an exhaust note that feels purposeful and well judged, whether paired with the factory rear silencer or an aftermarket rear section.

Built around an established design already proven on high-output V8 applications, this mid pipe is capable of supporting serious power levels while remaining fully usable for daily driving and fast road use. It’s an ideal foundation upgrade for G90 and G99 M5 owners who want to shape the character of their car without overspending or compromising balance.
