The best of both worlds: racing sound when you want it, refined comfort when you need it. This premium valved catback system gives your AMG GT R an extra 10-15 hp and complete audio control. From a silent cruise to an Affalterbach roar – at the touch of a button.
Why do AMG GT R owners choose this valved system?
- Switchable sound – racing sound or refined, you decide
- Power gain: +10-15 hp noticeable from day one
- Titanium or stainless steel – you choose weight or price
- Vacuum valvetronic – reliable and responsive
- Complete catback – from catalytic converter to tips
What makes this catback system so special?
Available in two premium finishes: Grade 2 titanium (ultimately lightweight, developing an iconic glow) or high-quality T304 stainless steel (durable and affordable). The Valvetronic system uses vacuum-controlled valves to regulate exhaust flow. Valves open = pure AMG racing sound that would make Affalterbach proud. Valves closed = refined and refined for everyday use.
The system completely eliminates the restrictive OE rear boxes. The result? A 10-15 hp power gain, instant throttle response, and that iconic AMG sound whenever you want. Suitable for the Mercedes-Benz AMG GT R R190. Tuning recommended for optimal results. Complete catback for maximum effect.
How does the installation work?
Complete bolt-on system – replaces everything from the catalytic converter onward. Professional installation is highly recommended for a perfect fit. Connect the vacuum lines to the valves and operate via the original equipment button or aftermarket controller. Weighs approximately 30 kg (titanium is lighter than stainless steel).
