CTS Turbo 8V RS3 and 8S TTRS 2.5T EVO Catless Downpipe
CTS Turbo is proud to announce our proprietary high-flow downpipe for 2017+ 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. 

Unfortunately, the Check Engine Light will come on after the installation; we strongly recommend using "stage 2" software because the CEL deletes or emulators are not compatible with these cars.


  • 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 (coming soon)


  • 2017+ Audi RS3 2.5T EVO (EA855)
  • 2017+ Audi TTRS 2.5T EVO (EA855)


To remove the CEL that will occur, proper tuning software must be used.

Use of stage 2 software upgrade is strongly recommended.
