Downpipe + 89mm cat CTS Turbo for Audi RS3/TTRS 8V/8Y 2.5T EVO

CTS Turbo is proud to announce our new single 3.5-inch high-flow catalytic converter downpipe for the 2018+ Audi 8V/8Y RS3/8S TTRS with 2.5L TFSI EVO engine (EA855).

This high-flow stainless steel downpipe allows the user to remove the restrictive factory "main catalytic converters."

We used CAD simulation to streamline exhaust flow and ensure it splits evenly into two outlets. Many hours of R&D went into ensuring a perfect fit, smooth exhaust flow, and excellent sound.

Y-pipe included for fitment with the factory exhaust.

Unfortunately, the Check Engine light will illuminate after installation. We strongly recommend using "stage 2" software, as CEL removers or emulators are not compatible with these vehicles.

Features:
- 3.5″ single downpipe
- Durable 304 stainless steel - laser-cut flanges and precision-machined V-band clamp
- Factory O2 sensor placement
- Designed with the latest 3D scanning technology
- Exhaust flow simulated with CAD software for optimal flow routing
- Aggressive sound, really makes this 2.5T scream
- No drone under normal driving conditions
- 200 cell CAT
- Driveshaft removal tool available separately as an option

Equipment:
- 2018+ Audi 8V/8Y RS3 2.5T EVO (EA855)
- 2018+ Audi TTRS 2.5T EVO (EA855)

A stage 2 tune is required to avoid the Check Engine light.
