EGO-X catback exhaust system 3,5" for Audi TTRS 8S and RS3 8V 400PS Facelift OPF

Applies only to one of the 3 following selections in the field "Selection of the operating mode": Exhaust flap control kit via switch / Exhaust flap control kit via remote control / Bull-X Tronic "Race" Can-Bus Control Unit

If the vehicle has a driving profile selection (sport button), it is also possible tobe controlled via this.
For vehicles without driving profile selection, this control can be done via a button that is included in the delivery.
The button's LED lighting indicates whether the flap is currently open (light off) or closed (light on)

If you have purchased the Bull-X Tronic control unit, it is still possible to open the valve when the vehicle is stationary, but the control unit regulates the exhaust valve in driving mode in accordance with ECE regulations.

Generally, the Bull-X Tronic offers two control options:
- Sport (Dynamic, Race)
- Comfort mode (valve opens from 75% throttle position)

The version "without ECE type approval" is not permitted for use in public road traffic in Germany - use only for racing purposes!!

ATTENTION! The offered exhaust system is not permitted in the area of the German road traffic licensing regulations! With the ECE Bull-X Tronic control unit and the EC catalytic converter you may legally use your vehicle in public road traffic. The use of all other controls and/or catalytic converters is only intended for racing purposes. If, despite our advice, you install an exhaust system WITHOUT ECE approval, you will be liable to prosecution. Imminent consequences can be, among other things: expiry of the operating licence, immobilisation of the vehicle, charges for tax evasion, as well as possible investigations by the environmental authorities.
