JCR Exhaust Valve Delete Kit for 991.2 & 992 Porsche 911 GT3, GT3 RS (with OPF), GT3 Touring, and Speedster

JCR Exhaust Valve Delete Kit for 991.2 & 992 Porsche 911 GT3, GT3 RS (with OPF), GT3 Touring, and Speedster

Many owners of the latest-generation GT3 RS and 911 Speedster have noted the more subdued exhaust note in factory form but prefer to retain the OEM exhaust system. JCR’s Valve Delete Kit provides a quick and simple solution, dramatically enhancing the car’s sound by locking the exhaust valves in the open position while ensuring no risk of triggering check engine lights.

The Design

• JCR has engineered the OPF Valve Delete Kit to be fully reversible and quick to install, with no risk of triggering a check engine light.

More Aggressive Sound

• On factory GT3 RS and Speedster models equipped with OPF and electronic valves, the OPF acts as a sound suppressor, while the valve function also plays a role in the subdued factory exhaust note. By deleting the valve control and locking the valves in the open position, the JCR kit improves sound at lower RPM and ensures unrestricted volume at higher RPM, where factory valve motors can otherwise close and significantly reduce exhaust tone.

• Deletes factory valve function
