Many owners with the latest generation GT3 RS and 911 Speedster have noticed a much more tame exhaust note in factory trim but do not want to replace the factory exhaust system. The JCR Valve Delete Kit allows owners to make a dramatic improvement to the sound of the car with a simple and quick to install kit of parts which locks the valves in the open position without any chance of check engine lights.

The Design

We have worked carefully to ensure that the JCR OPF Valve Delete Kit is fully reversible and is also quick and easy to install with no chance of a CEL.

More Aggressive Sound

The factory GT3 RS and Speedster are both installed with OPF and electronic valves. The OPF acts as a sound suppressor in its own right however the valve function also has a part to play in the tame nature of the factory exhaust note. Deleting the valve from the exhaust and locking the valve into the open position not only improves sound at the lower RPM ranges but also high end when under certain circumstances the factory valve motors can close and heavily restrict the sound.
