CTS Turbo is proud to announce our proprietary high-flow downpipe for 2018+ Audi 8V RS3/8S TTRS with 2.5L TFSI EVO (EA855) engine. 

This stainless steel high-flow downpipe that allows the user to remove the restrictive factory "main catalytic converters". This downpipe is a part of our modular exhaust system and it is compatible with factory or CTS Turbo mid-pipes. 

We used CAD simulation to streamline the flow of exhaust gasses and ensure that it splits evenly into two outlets. Many hours of R&D were spent to ensure perfect fit, smooth exhaust flow and excellent sound. 


  • Large 3.5" downpipe outlet splitting into dual 2.5" pipes
  • Durable 304 food-grade stainless steel
  • Laser cut flanges and precision machined v-band 
  • Factory-like placement of O2 sensors
  • Designed using the latest 3D scanning technology
  • Exhaust flow simulated with CAD software to ensure optimal flow routing 
  • Perfect fit with factory or aftermarket mid-pipes
  • Aggressive sound - really makes that 2.5T scream
  • No drone under normal driving conditions 
  • Optional driveshaft removal tool (based on factory Audi tool, required to remove and install driveshaft)
