IRL G90 G99 M5 Axleback Exhaust

The V2 exhaust for the G90 G99 M5 was engineered to deliver the ideal balance of refinement, performance, and an unforgettable driving experience.

At the core of the system is a carefully designed valved architecture that enhances exhaust flow while preserving the sophisticated character the G90 M5 is known for. The result is sharper throttle response, stronger top end power, and a deeper, more aggressive tone without introducing excessive drone.

With the valves closed, the system remains civilized and comfortable for daily driving. Open the valves, and the S68 twin turbo V8 comes to life with an exotic, Motorsport inspired sound that transforms every drive into an event.

Unlike systems that focus solely on volume, the V2 was developed to maximize real world performance while maintaining the refinement expected from a flagship M car. Larger-diameter tubing and optimized crossover sections help reduce backpressure and improve exhaust scavenging, which can contribute to measurable horsepower gains and a more responsive powerband.
