The Milltek Sport Cat Back Non-Resonated exhaust system is designed for Audi R8 V8 4.2 FSI Quattro models with a naturally aspirated V8 engine. This system replaces the section of the exhaust system after the catalytic converter and provides a significantly sportier and more open sound than the original exhaust system.

The Non-Resonated design eliminates mid-range damping, further freeing up sound and flow – the perfect choice for the driver who wants the R8 V8 engine to sound clear and pure.

Powerful and clean sound of a free-breathing V8

Milltek has tuned this exhaust system to bring out the character of the Audi R8 V8 engine in a genuine and sporty way:

• Deeper and fuller sound at idle

• Sporty sound as the load increases

• No annoying resonance or drone when driving on the road

The Non-Resonated structure brings more openness and presence to the sound while maintaining a controlled and usable overall sound.

Improved flow and ride feel

Milltek Cat Back Non-Resonated Exhaust System:

• reduces exhaust back pressure

• supports the engine's sensitive throttle response

• enhances exhaust gas flow throughout the entire rev range

• emphasizes the rev sensitivity and mechanical sound of the V8 engine

The freer-flowing design is ideally suited to the characteristics of a naturally aspirated V8 engine.

Direct bolt-on installation

The exhaust system is designed:

• to fit directly into the original mounting points of the Audi R8

• for installation without welding or permanent changes

• to preserve the car's original structures and systems

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 offers:

• 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.
