• Quiet and comfortable operation

The result is a more discreet exhaust character that complements the luxury-focused nature of the W222.

Open the valves and experience a deeper, fuller, and more aggressive exhaust note.

The freer-flowing exhaust path creates a stronger exhaust presence under acceleration while delivering a more performance-oriented driving experience.

Ideal for:

• Sport driving

• Hard acceleration

• Dynamic driving

• High-load conditions

• Drivers who want a more aggressive exhaust sound

Engineered for the Mercedes-Benz W222

The W222 S-Class is renowned for combining luxury, technology, and effortless performance.

The OAO Valvetronic Exhaust System is designed to complement this balance by providing adjustable exhaust sound without compromising the sophisticated character of the S-Class.

Whether cruising through the city or accelerating on an open road, the valve-controlled configuration gives the driver greater control over the vehicle's exhaust personality.

High-Flow Performance Design

The exhaust system features a performance-oriented internal design developed to improve exhaust gas flow and reduce unnecessary restriction within the exhaust path.

Optimized exhaust routing helps create a deeper and more pronounced exhaust tone while maintaining a smooth and refined character.

The system is engineered to provide a balanced combination of:

• Improved exhaust flow

• Enhanced exhaust sound

• Reduced exhaust restriction

• Sportier driving character

• Adjustable sound levels

Premium Stainless Steel Construction

Constructed from high-quality stainless steel, the OAO exhaust system is designed for strength, durability, and resistance to the demanding temperatures experienced within a high-performance exhaust environment.

The material selection provides a strong balance between durability, performance, and long-term usability for the W222 platform.

Precision TIG Welding

Each major exhaust component is precision TIG welded to achieve clean joints, consistent fabrication, and reliable structural strength.

Careful welding and fabrication help ensure proper fitment while maintaining the premium appearance expected from a high-end aftermarket exhaust system.

A More Emotional V8 Sound

For compatible V8-powered W222 configurations, the OAO Valvetronic Exhaust System enhances the natural character of the engine with a deeper and more authoritative exhaust tone.

With the valves closed, the system maintains a refined character suitable for everyday luxury driving.

With the valves open, the exhaust note becomes noticeably stronger and more aggressive, bringing a sportier personality to the S-Class.

From quiet luxury to full-blooded performance — control it your way.

Premium Exhaust Tips

The system is finished with premium exhaust tips designed to complement the rear styling of the Mercedes-Benz W222.

The larger and more performance-oriented appearance adds a subtle motorsport-inspired touch while maintaining the elegant proportions of the S-Class rear fascia.

Direct-Fit Design

The OAO Valvetronic Exhaust System is developed around the original W222 exhaust layout for a direct-fit installation concept.

OEM mounting locations and vehicle-specific exhaust routing help simplify installation while maintaining proper exhaust clearance.

Professional installation is recommended to ensure correct alignment, valve operation, and exhaust-system clearance.
