CTS TTRS/RS3 4 High Flow Downpipe features a CNC machined 4 T304 stainless steel V-band flange and turbo outlet.

Our 4 mandrel-bent stainless steel design is free of obstructions and uses a premium core interlock style flex section. For optimal clearance between downpipe and driveshaft, our design splits from a 4design to a dual 2.5 design where two more stainless steel flanges mate seamlessly to your secondary catalysts or high flow mid-pipes.

Each downpipe is hand-built to order at our facility, and test fitted in our hand made jigs to ensure exact fitment each and every time. In addition to the quality craftsmanship and great sound.

To remove the Check Engine Light that will occur, proper tuning software must be used. This downpipe works with ANY brand stage 2 software.

Fitment:

• 2009-2013 Audi TTRS 2.5T
• 2011-2012 Audi RS3 2.5T

Stage 2 software is required to avoid check engine light.
