The Milltek Axle-Back exhaust system is designed specifically for the BMW M5 G90 and G99 models with the 4.4-liter TwinTurbo hybrid powertrain. The system replaces the rear mufflers (the part after the axle) and retains the functionality of the car's original exhaust aftertreatment system and hybrid system.

This is an ECE-approved version that is suitable for road use without separate modification inspections in the ECE area (model and country-specific regulations must be taken into account).

Designed for G90/G99 platform

The exhaust system has been developed specifically for the BMW M5 G90 Sedan and G99 Touring models, with the fit, valve timing and sound optimized for the S68 4.4L V8 TwinTurbo hybrid powertrain of that generation. The system works in conjunction with the original exhaust valve timing.

Features

• ECE approved for road use

• Axle-Back structure (replaces rear shock absorbers)

• Direct bolt on installation

• Compatible with original flaps

• Made of high quality stainless steel

• Available with different output options

Sound and driving experience

In keeping with Milltek's design philosophy, the system brings out the character of the V8 engine more clearly, while maintaining a controlled and ECE-compliant sound level. With the valves closed, the sound remains subdued in everyday driving, and with the valves open, the exhaust system produces a deeper and more powerful tone under load.

Fit

• BMW M5 (G90) 4.4L TwinTurbo Hybrid

• BMW M5 Touring (G99) 4.4L TwinTurbo Hybrid
