CTS Turbo B6 Audi A4 Test Pipe

The CTS Turbo Test Pipe is engineered specifically for B6 Audi A4 models from 2002 to 2005, replacing the factory catalytic converter to reduce exhaust backpressure and unlock improved throttle response. Precision-mandrel bent from high-grade stainless steel, this test pipe removes a significant restriction point in the exhaust system, allowing turbocharged engines to breathe more freely. Direct bolt-on installation simplifies fitment using factory mounting points. Intended for off-road motorsport use only. A professional solution for performance-focused workshops building serious street and track Audi platforms.
