Key Facts about the Exhaust System

• Registration-Free: Thanks to our own valve control module and ECE approval, the exhaust system is registration-free in all countries with ECE regulations.
• Intelligent Valve Control: Our ECE module ensures legal operation by controlling the exhaust valves correctly, allowing you to drive worry-free.
• 3.5'' Pure Fun: The large 3.5'' pipe diameter delivers a deep, dominant, and aggressive sound.
• Maximally Legal Loudness: This straight pipe system operates at the edge of legality and offers a volume that you can enjoy without concern.
• 100% Fitment: With our years of experience in tuning, we proudly guarantee that each of our exhaust systems fits with 100% accuracy.

Additional Components

We also offer other components to further enhance your M3 F80 Competition:

• Special intake systems
• Custom intercoolers

Important Notes

Please note that not every original BMW valve module controls the exhaust valves according to official ECE guidelines. There may be minor deviations that cannot be legalized in combination with an aftermarket exhaust system. Therefore, we recommend our own valve control module with ECE approval, which fully complies with legal requirements and legalizes the Exhaust.one system.

If you have already installed other components on your M3 (e.g., power upgrades, intercoolers, intake systems) or plan to add them in the future, our ECE approval will be void, and a new combination approval at the TÜV will be required.
