BlackBoost Exhaust Valve Module | for Mercedes AMG GT53 (290) M256 3.0L I6 Turbo

"Factory exhaust flaps open to a maximum of 70%.
BlackBoost EVM opens the flaps 100% at any time, any speed, in any mode."

Take full control of your AMG E63/GT63 exhaust sound with the BLACKBOOST Exhaust Valve Module. This plug-and-play solution allows you to open your exhaust valves 100% at any time by simply pressing Button 1 on the included remote control. Want to return to the stock valve operation? Just press Button 2.

Whether you're cruising at low RPMs or pushing your AMG E63/GT63 to the limit, the EVM gives you complete command over your exhaust system, independent of speed, RPM, or driving mode. Perfect for enthusiasts who want to enjoy maximum exhaust sound on demand and switch back to factory behavior whenever desired.

Advantages of the BlackBoost Exhaust Sound Control:

• Independent Activation: Gain full control of your exhaust valves regardless of the vehicle’s drive mode. Override the factory settings instantly with the push of a button.
• Non-Intrusive Design: The EVM operates independently from the vehicle’s CAN-Bus system, ensuring:
  • No interference with factory control units.
  • Continued functionality even after software updates.
  • Zero wire cutting or cable damage – completely plug-and-play and fully reversible.

What's Included:

• 1 x Exhaust Valve Module
• 2 x Remote Controls (Button 1 Fully open, Button 2 back to Stock)
• Wiring harness (model specific)
• Installation manual

Please Note:

• Factory Exhaust Valves Required: Before placing your order, please confirm that your vehicle is equipped with factory-installed exhaust valves. The BlackBoost EVM will not function on vehicles without them.
• Easy Installation: The EVM unit is installed in the trunk – no hard wiring or modifications required.
• Convenient Functionality: When activated in Position 1 (Button 1), the exhaust valves will remain fully open – even after turning the vehicle off and restarting it. The system will only return to factory settings when Button 2 is pressed.
