Kies Valve Controller Porsche 992.2 GTS and 992.1 / 992.2 GT3 / GT3 RS / GT3 Touring and 95B Macan
Kies Valve Controller
Complete exhaust valve command for Porsche 991.2/992 GT3 • GT3 RS • GT3 Touring • 992.2 GTS • 982/718 Boxster • 982/718 Cayman
Unleash the True Sound of Your Porsche
Experience the raw, unfiltered exhaust note your Porsche GT3, GT3 RS, Boxster, or Cayman was engineered to produce. The Kies Valve Controller gives you complete command over your exhaust valve system across multiple high-performance Porsche platforms — from the track-focused GT3 to the agile mid-engine Boxster and Cayman lineup.
From the factory, Porsche's exhaust valve system includes built-in sound management for emissions and noise compliance. Even when you select “valves open” mode, the system automatically restricts valve opening at idle and lower RPMs. The Kies Valve Controller eliminates these factory restrictions, allowing you to fully open the exhaust valves whenever you choose.
Key Features
Full Valve Override
Eliminates factory RPM-based valve restrictions. Valves stay fully open at idle and all RPM ranges when activated — delivering the raw, unfiltered exhaust note your engine was built to produce.
Wireless 2-Button Remote
Button 1: Full valve opening — maximum sound and track-ready exhaust flow.
Button 2: Instant return to factory valve behavior for street driving. Range: ~50–100 ft.
Plug-and-Play Installation
Installs inline between the factory valve actuators and OEM control unit using OEM-style connectors. No cutting, splicing, or permanent modifications required.
Platform-Specific Engineering
Specifically calibrated for GT3, GT3 RS, GT3 Touring, 992.2 GTS, and 982 Boxster/Cayman exhaust valve architecture — not a generic one-size-fits-all solution.
Safety Mechanisms Built In
Intelligent programming prevents valves from remaining fully closed continuously, protecting against excessive exhaust back-pressure during sustained high-RPM track use.
Fully Reversible
No permanent changes to your vehicle. Remove the controller at any time to restore factory configuration — ideal for service visits, resale, or noise-restricted environments.

How It Works
The Kies Valve Controller intercepts the signal between your car’s ECU and the valve actuators. When you activate Button 1 on the wireless remote, the controller overrides the factory signal and commands the valves to remain fully open regardless of RPM, throttle position, or drive mode. Button 2 passes the factory signal through unchanged, restoring original valve behavior instantly.
Installation Steps
- Safely raise and secure vehicle on jack stands or a lift for access to exhaust components. Bumper removal is necessary.
- Locate exhaust valve actuators (GT3: rear-mounted; Boxster/Cayman: side-mounted underneath).
- Carefully unplug OEM connectors from the valve actuators.
- Install the Kies module inline between the factory harness and valve actuators using the supplied OEM-style connectors.
- Secure the controller module in a protected location using the provided mounting hardware.
- Follow the simple pairing procedure to sync the wireless remote with the controller.
- Start the vehicle and verify both button functions at idle and while driving.
- Confirm all connections are secure and routed away from heat sources.
Professional Installation Recommended
The Kies Controller should be installed by Porsche specialty shops and performance exhaust shops nationwide. Installation can take up to 8 hours.
Important Disclaimers
What This Product Does NOT Modify
This is a sound and driving-experience enhancement only. It does not modify boost targets, wastegate strategy, torque limits, ignition timing, fuel trims, lambda targets, turbocharger shaft speed limits, or any engine calibration parameter. It does not tune, flash, or alter your ECU in any way.
⚠ Notice for T-Hybrid / E-Turbo Owners (992.2 GTS)
The valve controller itself does not change turbo shaft speeds or any calibration parameter. However, community reports have documented e-turbo failures on T-Hybrid vehicles running OPF-delete downpipes and aggressive free-flow midpipes — failures associated with exhaust hardware changes, not valve controllers alone.
If you are stacking this controller with other exhaust modifications on a T-Hybrid vehicle, we strongly recommend: (1) avoiding generic off-the-shelf tunes paired with major exhaust hardware changes, and (2) working with a qualified tuner who can datalog turbo shaft speed, EGTs, and knock. If you are purchasing this controller purely for valve control on an otherwise stock T-Hybrid vehicle, these concerns do not apply.
Naturally Aspirated Applications (GT3, GT3 RS, GT3 Touring, 982/718 Boxster & Cayman)
For all naturally aspirated applications covered by this controller, the turbo-related concerns above do not apply. This controller has a long track record as a safe, reversible sound and driveability modification on these platforms.
Intended Use
This product is designed for off-road and closed-course use only. Holding exhaust valves open may cause the vehicle to exceed local sound ordinance limits and may not comply with emissions regulations in your jurisdiction. It is the purchaser’s responsibility to understand and comply with all applicable laws.
Warranty Scope
Kies Motorsports warrants this controller against manufacturing defects for 1 year from the date of purchase. We do not warrant, and are not responsible for, any damage to OEM exhaust valve actuators, control modules, turbochargers, catalysts, particulate filters, or any other vehicle component resulting from use in combination with other aftermarket modifications, tunes, or hardware changes.
