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 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 drone. 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.
