• The Exhaust Sport Valvetronic Silencer is a performance upgrade designed specifically for Porsche 718 GT4 RS
  
• This silencer replaces the stock exhaust system with a valvetronic setup, offering the ability to control the sound levels of the exhaust.
• The valvetronic system allows drivers to switch between different modes, offering a quiet and more subdued exhaust note for daily driving, and a louder, more aggressive sound for spirited driving or track days.
• The upgraded silencer enhances the overall exhaust flow, reducing backpressure and increasing horsepower and torque output.
• It can provide a deeper, more exhilarating exhaust note, offering a more sporty and engaging driving experience.
• Consider local regulations and laws regarding emissions and noise levels before purchasing and installing this upgrade.
• Default position of the valve is OPEN. The car will start loud if there is no vacuum in the system and will need few seconds to build up the vacuum to close the valves.
