DEVELOPMENT: Our goal was to offer a valved exhaust that delivers a refined cabin presence. It is easy to increase the volume of the 718, but a challenge to bring out a more aggressive note while making the flat-four sound distinctly Porsche which is a common complaint. The turbo and a large amount of sound deadening in the 718 do a great job of keeping the cabin calm, but raising the volume to compensate can bring out negative notes in the exhaust such as rasp and drone. We applied the same design principles as our renowned Valved Exhaust line for previous Boxster / Cayman generations to deliver a refined increase in sound that will also pair well with an upgraded, freer flowing downpipe to yield a mature exhaust note without ever being overbearing. This is a superior option for cars not equipped with the Porsche Sport Exhaust from the factory.
CONSTRUCTION: Each system is made from mandrel-bent T304L stainless steel tubing (featuring 2.5″ OD over axle pipes) and features mufflers with fortified casings in the interest of durability. With valves closed the exhaust gasses are routed into the SOUL muffler, which is packed with high-quality sound deadening material designed to withstand abuse and not blow out over time. The mufflers are incredibly effective at minimizing drones. Exhaust gasses make their way through the muffler and out through perforations into the outer piping. With valves open, exhaust gasses are now free to exit out through large 2.5″ piping while perforations allow exhaust gasses to “talk” with the muffler, encouraging a fuller, more robust tone.
SOUND: You could describe the sound experience as PSE Plus! The tone in the cabin with valves open is about the same as PSE, not intrusive at all. Under heavy load the volume difference is noticeable, more aggressive while still refined. With valves closed, you can carry on a phone conversation on the highway without any intrusion from the exhaust. When paired with an upgraded downpipe / catalytic converter the exhaust offers a respectable level of snarling and crackling without droning at all RPM and throttle loads. Sport mode unleashes an increase in crackles and burbles.
VALVE OPERATION: A valve controller is included with every system and is required for non-PSE cars. PSE-equipped cars will retain full factory functionality by using the factory vacuum lines. The valve controller is optional for PSE-equipped cars and allows full valve control at all times. Valve functionality can be controlled by the factory PSE button, included valve controller fobs, and with HomeLink buttons.
TIPS: Choose from several different tip styles and finishes. Single wall tips have around a half-inch of depth adjustment to allow for the tips to be sunk in to just show the logo at their deepest and pulled out more if desired. Double-wall chrome tips are longer in length by 1″ and protrude from the bumper aggressively. Logo customization is available, please contact us.
BOLT ON AND GO: Each exhaust is rigorously quality-checked, tested in a fixture to guarantee fitment, then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
