The Milltek Sport Cat Back exhaust system is designed for Mercedes-AMG GT, GTS and GTC models (Coupe and Roadster) that do not have a factory-fitted OPF/GPF particulate filter. This system replaces the exhaust section after the catalytic converter and unleashes the sound and flow of the 4.0-liter V8 biturbo engine in a controlled and sporty manner.

The Cat Back solution improves exhaust flow and emphasizes the character of the AMG engine while maintaining the car's everyday drivability and premium comfort.

The controlled and sporty sound of the AMG V8

Milltek has tuned this system to bring out the character of the AMG V8 in a clear yet balanced way:

• Deeper and fuller sound at idle

• Sporty sound as the load increases

• No annoying resonance or drone when driving on the road

The sound profile is clearly sportier than the standard system, without becoming tiring in everyday driving.

Improved flow and ride feel

Milltek Cat Back Exhaust System:

• reduces exhaust back pressure

• supports the engine's sensitive throttle response

• enhances exhaust gas flow throughout the entire rev range

• complements the use of the engine's torque and power range

The freer-flowing structure is ideally suited to the characteristics of AMG's V8 biturbo engine.

Direct bolt-on installation

The exhaust system is designed:

• to fit directly into the original mounting points of Mercedes-AMG GT models

• for installation without welding or permanent changes

• to preserve the car's original systems and structures

OEM-level fit ensures a clean and unobtrusive finish.

304L Aircraft Grade Stainless Steel

The entire system is made of high-quality 304L grade stainless steel , which provides:

• excellent corrosion and heat resistance

• long service life even in demanding driving

• flow-optimized internal structure

• carefully finished TIG welds

The material and workmanship meet Milltek's premium quality standards.
