CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 1.8T/2.0T Test Pipe

The CTS Turbo test pipe is engineered for B8 and B8.5 generation Audi vehicles equipped with 1.8T or 2.0T turbocharged engines. This direct replacement component eliminates the factory catalytic converter, significantly reducing exhaust backpressure and allowing the turbocharger to operate more efficiently. Precision-manufactured from high-grade materials with CNC-machined flanges, it provides a substantial improvement in throttle response and turbo spool characteristics. Designed specifically for A4, A5, AllRoad and Q5 models between 2010 and 2016, this test pipe installs using OEM mounting locations for straightforward fitment during performance upgrades.
