The CTS Turbo 3.5″ stainless steel race downpipe for VW Golf R and Audi S3 is designed for more efficient exhaust gas flow. The factory downpipe heavily restricts exhaust flow, which can affect performance, especially on vehicles with optimised engine software. The CTS Turbo downpipe enables smoother exhaust gas flow, while the modular design simplifies catalytic converter installation. Smooth transitions ensure optimal exhaust gas flow.
Product details:
- Seamless T304 stainless steel pipes
- T304 stainless steel flanges
- 100% TIG welded
- T304 stainless steel O2 sensor connection
- Torca Accuseal stainless steel clamps
- Pleasant sound even with the factory exhaust system, without annoying drone
Suitable engine optimisation software is required to remove the engine warning light (CEL) that may appear. Using an additional CEL delete device greatly reduces the possibility of a catalyst efficiency fault, but does not eliminate it completely.
To make full use of the engine sound, we recommend disabling the Soundaktor system, which can cause additional unwanted drone.
Stage 2 software is required to prevent the engine warning light from appearing.
