CTS Resonator Delete Kit - B9 Audi S4 3.0T

The CTS Turbo Resonator Delete Kit for B9 Audi S4 3.0T models removes the factory exhaust resonators that dampen sound and restrict exhaust flow. Engineered specifically for 2017-2021 S4 platforms, this direct replacement kit features mandrel-bent tubing for smooth gas flow and straightforward installation. By eliminating the stock resonators, you'll experience a sportier exhaust note with enhanced turbo sounds whilst reducing backpressure in the exhaust system. Built from quality materials for durability and consistent performance under demanding conditions.
