CTS Turbo B9 Audi RS5 Test Pipes

CTS Turbo test pipes are engineered specifically for the B9 Audi RS5 from 2018 through 2021, replacing the factory catalytic converters with smooth-flowing straight pipes. These precision-manufactured components eliminate exhaust restrictions, reducing backpressure to allow the 2.9-litre twin-turbo V6 to breathe more freely. The direct bolt-in design ensures proper fitment without modification, while the improved flow characteristics complement other performance upgrades. Expect a notably more aggressive exhaust note alongside enhanced throttle response. Professional installation recommended. Check local emissions regulations before fitment.
