Valvetronic Exhaust Control

The integrated electronic valve system allows the exhaust sound to be adjusted according to your driving conditions and personal preference.

This configuration is ideal for:

• Daily commuting

• City driving

• Highway cruising

• Long-distance travel

• Comfortable driving

The result is a more discreet exhaust character while maintaining the premium feel of the W205.

Valve Open — Sport & Aggressive

Open the valves to unlock a deeper, louder, and more aggressive exhaust sound.

The freer-flowing exhaust path increases exhaust presence during acceleration and gives the W205 a more performance-oriented character.

Ideal for:

• Sport driving

• Dynamic acceleration

• Weekend driving

• High-load conditions

• Performance applications

One exhaust system. Two distinct personalities.

High-Flow Cat-Back Performance Design

The OAO system replaces the exhaust components downstream of the catalytic converter with a performance-oriented cat-back configuration.

The optimized exhaust routing is designed to improve exhaust gas flow while reducing unnecessary restriction in the rear section of the exhaust system.

Potential benefits include:

• Improved exhaust flow

• More pronounced exhaust sound

• Sportier exhaust character

• Reduced exhaust restriction

• Enhanced driving experience

Actual performance gains may vary depending on the vehicle, engine configuration, and other modifications.

Premium Stainless Steel Construction

Manufactured from high-quality stainless steel, the OAO Cat-Back Exhaust System is engineered for durability, strength, and resistance to high exhaust temperatures.

The stainless-steel construction provides a balanced combination of:

• Durability

• Performance

• Heat resistance

• Corrosion resistance

• Premium appearance

Designed for long-term street and performance use, the system is built to withstand demanding driving conditions.

Precision TIG Welding

Key components are precision TIG welded for clean joints, consistent fabrication, and reliable structural integrity.

Every weld is carefully finished to maintain the premium appearance and structural quality expected from a high-end aftermarket exhaust system.

Enhanced Exhaust Sound

The OAO Valvetronic Cat-Back system is designed to give the W205 C-Class a stronger and more engaging exhaust character.

With the valves closed, the exhaust remains controlled and refined for everyday driving.

With the valves open, the system delivers a deeper and more aggressive tone under acceleration.

Depending on the exact engine and vehicle configuration, the system can enhance:

• Low-RPM exhaust tone

• Acceleration sound

• Throttle acoustics

• Sport driving character

• Overall exhaust presence

More character. More control. More driving emotion.

Engineered for the W205 C-Class

The W205 C-Class combines premium luxury with sporty handling and everyday usability.

The OAO Valvetronic Cat-Back Exhaust System is designed to complement this balance by adding an adjustable performance character without removing the versatility of the vehicle.

Whether you're commuting during the week or enjoying a spirited drive on the weekend, the valve-controlled design allows you to choose the exhaust personality that suits the moment.

Premium Exhaust Tips

The system is finished with premium exhaust tips designed to complement the sporty rear styling of the W205 C-Class.

The upgraded exhaust appearance provides a more aggressive visual presence while maintaining the clean and refined design language of the Mercedes-Benz platform.
