Product Description

The SOUL Valve Controller Kit gives you full manual control over the exhaust valves on your 718 GT4 / GT4 RS / Spyder / GTS 4.0L — letting you decide exactly when the exhaust is quiet or aggressive. Instead of relying on the factory valve logic, this kit lets you force the valves open for a raw, track-ready roar, or close them for a refined, street-friendly sound, all at the press of a button. It’s the perfect companion for a valved exhaust system or down-pipe upgrade, turning factory-style exhaust hardware into a fully driver-controlled sound system.

Fitment Notes

  • Compatible with Porsche 718 GT4, GT4 RS, 718 Boxster Spyder, and 718 Cayman/Boxster GTS 4.0L (2020 and newer). 

  • Intended to override the factory exhaust valve system (PSE/vacuum-controlled valves). 

  • Requires additional wiring and a vacuum signal to the valve-actuation solenoid — not a pure plug-and-play in all cases. 

  • Includes two key-fobs for valve control; kits can also integrate with a car’s HomeLink buttons for remote operation.

Included

  • Valve controller module (solenoid / control unit) for exhaust-valve actuation

  • Two wireless key-fobs for remote valve control (open / close)

  • Wiring harness and necessary wiring connectors (ground and switched 12 V source)

  • Installation instructions and warranty documentation (lifetime warranty by manufacturer)

Product Specs

  • Functionality: Allows manual override of factory exhaust-valve logic; valves can be forced open or closed at will. 

  • Control: Wireless remote (key-fobs) or optional integration with HomeLink system for button-based control.

  • Fitment Compatibility: 718 GT4 / Spyder / GTS / 4.0L (2020+) platform — suitable for 982-series 4.0L flat-six Porsche vehicles.

  • Warranty: Covered under manufacturer’s lifetime warranty — valid for both street and track use.

Product Features

  • Full Exhaust Sound Control — Choose when your exhaust is loud and aggressive or calm and quiet with a simple button push — perfect for switching between street driving and track sessions.

  • Override Factory Restrictions — Factory valve logic often closes valves at low RPM or under light throttle, even with “Sport / PSE” selected — this kit bypasses those restrictions so you get consistent valve behavior. 

  • Remote & Convenient Operation — Wireless key-fobs allow valve toggling without reaching into the cabin; can be synced with HomeLink for a clean, OEM-like interface. 

  • Track-Ready or Street-Friendly Versatility — Keep valves closed for stealthier street use or open for maximum exhaust drama on performance runs. Ideal for owners switching between daily driving and spirited track driving.

  • Lifetime Warranty — Built and supported by a performance exhaust specialist with lifetime-warranty coverage for street and track applications
