Performance Exhaust System for BMW M5 G90 G99 4.4T
Transform the sound, performance, and presence of your next-generation BMW M5 with the STRATEC™ High-Performance Exhaust System, engineered for the BMW G90 M5 Sedan and G99 M5 Touring equipped with the 4.4L twin-turbo V8 hybrid powertrain.
The factory G90/G99 M5 delivers enormous performance, but its exhaust system leaves significant room for enthusiasts looking for a more aggressive and engaging driving experience. The STRATEC™ system is designed to increase exhaust flow, reduce unnecessary restriction, and bring out a deeper, sharper, and more powerful V8 exhaust note.
Available in your choice of ultra-lightweight Grade 5 titanium or premium T304 stainless steel, this system provides two distinct material options while maintaining the same performance-focused STRATEC™ architecture.
Whether your M5 is a daily-driven luxury sedan, high-performance Touring build, or heavily modified performance car, the STRATEC™ exhaust provides the sound, craftsmanship, and flow capability the platform deserves.
