CTS Turbo 4M Audi SQ7/SQ8/RSQ8 Resonator Delete

CTS Turbo 4M Audi SQ7 / SQ8 / RSQ8 Resonator Delete

Unleash the sound of your 4.0T V8 twin-turbo!
The CTS Turbo Resonator Delete for the Audi SQ7, SQ8, and RSQ8 (4M chassis) is designed to replace the factory resonator section in the intake system. The OEM resonator is built to dampen and quiet down induction noise, but it also restricts airflow and dulls the raw sound of your engine.

By installing this upgrade, you’ll experience:

Enhanced Induction Sound – Enjoy the deep, aggressive turbo spool and whoosh that the factory resonator mutes.

Improved Throttle Response – Removing restriction allows smoother, more direct airflow into the turbos.

Durable Construction – Precision CNC-machined from high-quality aluminum for strength and reliability.

OEM+ Fitment – Direct bolt-in replacement for the stock resonator; no cutting or permanent modifications required.

Perfect for enthusiasts who want to hear more of their Audi’s 4.0T twin-turbo character without affecting emissions or requiring a tune.

Audi SQ7 4M 4.0T (2017–2025)

Audi SQ8 4M 4.0T (2019–2025)
