Never before has there been such a bassy and muffled 5 cylinder sound as with our new HPerformance 4 inch exhaust system. Designed in such a way that there is no annoying droning noise, either with the flaps closed or open.
Our 4" exhaust system for Audi RS3 8V, RS3 8Y, RSQ3 F3 and TTRS 8S meets all TÜV requirements and therefore comes with ECE approval. This means that the exhaust system can be driven without additional TÜV registration. ECE approval also enables registration in Switzerland.
