FAQ

1. How do the vacuum valves operate?

The system features precision vacuum-actuated valves with dual control versatility. You can connect them directly to your Porsche's factory vacuum lines to preserve OEM cabin exhaust button operation, or utilize the included CEES wireless remote key fobs and vacuum controller module to open and close the valves independently at any RPM.

2. Can I use my original factory Porsche exhaust tips?

Yes. The exhaust outlets are engineered to fit either the included CEES dual tips or your original factory Porsche GT4 RS / Spyder RS exhaust tips seamlessly.

3. Will installing this exhaust trigger a Check Engine Light (CEL)?

No. This valved sport catback exhaust system mounts downstream of the catalytic converters and factory monitoring sensors, ensuring 100% CEL-free performance without requiring an ECU tune.

4. Is cutting or welding required during installation?

No. The exhaust is precision-engineered from 3D laser-scanned data. 100% bolt-on installation allows a return to stock at any time. (Reuses factory outlets).

5. Are you a direct manufacturer?

Yes — CEES Exhaust is a direct manufacturer based in Guangdong, China. We laser-scan, bend, and TIG-weld every exhaust component in our factory with rigorous quality inspection.
