Gain Full Control Over Your 5-Cylinder Soundtrack

Take control of your Audi’s soundtrack with the RS3 Exhaust Valve Module by ASR, also known as ExValve. Designed for Audi RS3 8V FL and TTRS 8S (2017+), this plug-and-play controller lets you manage your factory exhaust valves with precision. Choose when you want quiet cruising—or unleash full 5-cylinder fury—at the push of a button.

Whether you’re navigating city streets or enjoying backroad blasts, this module puts the choice in your hands.

Plug-and-Play Simplicity, OEM Integration

Installation couldn’t be easier. The ExValve module connects directly to your OEM exhaust valve harness. No coding, cutting, or permanent changes are required. The included key fob remote allows instant switching between three modes: open, closed, or auto (factory default). You can even retain your last selected mode when restarting the vehicle.

Because it integrates so cleanly with the OEM system, you’ll maintain all factory safeguards and diagnostics—without triggering warning lights or errors.

Key Features:

• ✅ Fits Audi RS3 8V FL (2017–2020) and TTRS 8S (2017–2023)

• ✅ Remote-controlled exhaust valve management – open, closed, auto

• ✅ Plug-and-play – no coding or wire splicing

• ✅ Retains OEM features and startup behavior

• ✅ Includes compact remote with memory function

Pair with our TTRS 8S Midpipe Upgrade or RS3 Valved Cat-Back System for the ultimate exhaust flexibility.
