Optional Exhaust Valve Controller

An optional exhaust valve controller can be added to provide greater control over the factory valved exhaust system.

From factory, the Porsche ECU automatically controls the exhaust valves based on RPM, engine load and selected driving mode. This means the valves can close at certain points in the rev range even when a louder exhaust setting has been selected.

The optional valve controller allows the driver to override the factory RPM-based valve strategy, giving direct control over the exhaust valves when desired.

Features

• Override the factory RPM-based exhaust valve control

• Keep the exhaust valves open when desired

• Retain the ability to return to normal factory-controlled operation

• Allows more consistent exhaust sound throughout the rev range

• Works with the factory valved exhaust system

• Discreet installation with no changes to the appearance of the exhaust

• Ideal addition when upgrading the over axle pipes or other exhaust components

Why Upgrade?

The factory over axle section forms part of the restrictive exhaust path between the headers and rear exhaust system. Replacing these pipes with a freer-flowing design helps reduce exhaust restriction and complements other exhaust upgrades, particularly on vehicles fitted with aftermarket headers or rear muffler systems.

The result is a sharper, more engaging exhaust note while retaining a clean, factory-style installation.
