The CLS 450, known for its elegant design and turbocharged inline-six engine with EQ Boost, deserves an exhaust that complements its refined power—and Yonristic delivers just that.

Constructed with precision-engineered 3-inch piping, this system optimizes exhaust flow, reducing backpressure and enhancing throttle response. The result? A deeper, more aggressive exhaust note accentuates the CLS 450’s performance while maintaining a comfortable and refined tone for daily driving.

At the heart of this exhaust system is Yonristic’s specialized muffler design, carefully developed to provide the best combination of sound quality and power output. The system fully integrates with the factory valve control, ensuring seamless operation with your vehicle’s original settings. This allows you to switch between a quiet, refined mode for city driving and an exhilarating, full-bodied exhaust note when you unleash the power of your CLS 450.

Designed with perfect fitment, the bolt-on, slip-on-free construction eliminates the need for slip joints, ensuring maximum durability, leak prevention, and an OEM-like installation experience. This system is crafted from T304 stainless steel or Grade 5 titanium, offering superior strength, longevity, and up to 65% weight reduction with the titanium option.
