Capristo Valve Controller

Take control of your Porsche 992's exhaust sound with the Capristo E2E Exhaust Valve Remote Kit H. Designed for vehicles equipped with factory electronic exhaust valves, this plug-and-play controller allows drivers to manually override the factory ECU's exhaust valve commands and keep the valves open for maximum exhaust volume and a more engaging driving experience.

From the factory, Porsche electronically regulates exhaust valve operation based on engine speed, throttle input, driving mode, and other operating conditions. Even with the sport exhaust activated, the valves may close at certain engine speeds or under specific driving conditions.

The Capristo E2E controller provides a convenient solution by allowing drivers to override this factory behavior using a wireless remote, unlocking a more pronounced flat-six exhaust note whenever desired.

Featuring a vehicle-specific wiring harness, the system integrates directly with the factory electronic exhaust valve connections without cutting, splicing, or permanently modifying the original wiring.

Compatible with numerous Porsche 992 Carrera, Turbo, Turbo S, Targa, Dakar, and Sport Classic applications, the Capristo E2E Exhaust Valve Controller is an excellent upgrade for owners who want greater control over their vehicle's exhaust sound without replacing the factory exhaust system.

Why Upgrade?

Porsche's factory sport exhaust systems are engineered to balance performance, sound regulations, and everyday refinement.

Although selecting Sport or Sport Plus mode can change exhaust valve behavior, the vehicle's ECU may still close the valves under certain operating conditions.

For enthusiasts who want a more consistent and aggressive exhaust note, the Capristo E2E Exhaust Valve Controller provides greater flexibility without requiring a complete exhaust replacement.

Keep Your Exhaust Valves Open

The primary advantage of the Capristo E2E system is the ability to manually override factory exhaust valve operation.

Rather than relying exclusively on Porsche's programmed exhaust valve strategy, drivers can command the valves open using the supplied wireless remote.

This allows more of the engine's natural exhaust sound to be heard, particularly in situations where the factory ECU would otherwise close the valves.

More Sound Without Replacing Your Exhaust

Not every Porsche owner wants to replace the factory exhaust system.

The Capristo E2E controller offers an alternative for vehicles already equipped with an electronically valved exhaust.

By changing valve behavior, the controller can produce a more pronounced exhaust note without modifying the mufflers, catalytic converters, or exhaust piping.

The actual increase in volume depends on the vehicle's existing exhaust configuration and the difference between its open and closed valve positions.

Simple, Reversible Installation

The E2E system uses a dedicated plug-and-play wiring harness that connects directly to the factory electronic exhaust valve wiring.

Because the installation does not require cutting or permanently altering the original wiring, the controller can be removed and the original connections restored if desired.

No ECU flash or engine tuning is required.

An Excellent Addition to Performance Exhaust Upgrades

For Porsche owners installing compatible aftermarket valved exhaust systems, the Capristo E2E controller can provide additional flexibility over exhaust sound.

This is particularly useful for systems that retain Porsche's factory electronic valve actuators but remain subject to the original ECU valve-control strategy.

When paired with a compatible valved exhaust, the E2E allows drivers to take fuller advantage of the system's open-valve sound characteristics.

Enhance your Porsche 992's exhaust sound with the Capristo E2E Exhaust Valve Controller—featuring wireless remote operation, plug-and-play installation, and manual override of factory electronic exhaust valves for a more engaging driving experience.
