The CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 1.8T/2.0T Test Pipe is the premier test pipe for your Audi. Our test pipe is designed to seamlessly replace the restrictive factory catalytic converter, which is located immediately after the turbocharger. It features 3-inch stainless steel piping, smooth mandrel bends, and two O2 sensor bungs with the option for a third. Significant power gains, improved exhaust flow, and a deeper, throatier exhaust note are the main benefits of installing this test pipe.

Upon inspection, you will notice a flare measuring nearly 4 inches, which then tapers down to 3 inches. This design allows for optimal exhaust gas flow as it transitions from the turbocharger into the test pipe. In addition to being one of the best bang-for-the-buck performance upgrades for A4/A5/AllRoad and Q5 owners, this test pipe is also a very attractive component. Each 3-inch test pipe is mandrel-bent and hand TIG welded. Need an additional O2 bung for data logging? No problem — an extra O2 bung is now included at no additional charge!

Product Details:

  • Direct replacement for the factory component
  • 304 stainless steel construction
  • Mandrel-bent stainless steel tubing
  • Fully TIG welded design with reinforced welds at the flanges
  • Extra O2 bung for wideband sensor
  • Installation hardware included
  • Throaty exhaust sound
  • Excellent power upgrade
  • To eliminate the CEL that will occur, proper tuning software must be used

Use of Stage 2 software is strongly recommended.
