Description
The BMW G20 M340i and G22 M440i are among the most celebrated modern BMW performance platforms, powered by the legendary B58 turbocharged inline-six engine. Renowned for its smooth power delivery, impressive tuning potential, and everyday usability, the B58 deserves an exhaust system that amplifies both its performance and character.
The Yonristic Performance Valved Exhaust System is engineered to unlock the full potential of the G2X platform. Combining increased airflow, precision acoustic tuning, advanced valve control, and premium construction materials, this cat-back system transforms the M340i and M440i into a more responsive, engaging, and exhilarating driving machine.
Whether you're commuting, cruising, or pushing the limits on your favorite back road, the Yonristic Exhaust System delivers the perfect balance of refinement and aggression.
Engineered for Maximum Flow and Performance
At the core of the system is a high-flow exhaust architecture featuring a 3.5-inch front section that transitions into true 3-inch mandrel-bent piping. This design minimizes restriction while maintaining optimal exhaust velocity, allowing the B58 engine to breathe more efficiently.
By reducing backpressure and improving exhaust scavenging, the system enhances throttle response and overall engine performance across the entire RPM range.
