CTS Turbo 8V/8Y RS3 and 8S TTRS 2.5T EVO 3.5" Single High-Flow Cat

CTS Turbo is proud to announce our new single 3.5″ High-Flow CAT for 2018+ 8V/8Y 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”.

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.

Y pipe included for fitment with factory exhaust.

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.

Features:
– Single 3.5″ race downpipe
– Durable 304 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
– Aggressive sound – really makes that 2.5T scream
– No drone under normal driving conditions
– 200 Cell CAT
– Optional driveshaft removal tool available separately

Fitment:
– 2018+ 8V/8Y RS3 2.5T EVO (EA855)
– 2018+ TTRS 2.5T EVO (EA855)

Stage 2 software is required to avoid check engine light.
