Porsche 718 Boxster and Cayman Competition Package
Premium quality mufflers and freer flowing downpipe provides more power, response, and turbo sound. Upgrade to an aggressive exhaust setup without sacrificing a refined cabin experience – experience mild to wild at the press of a button!
DEVELOPMENT AND TESTING: Our goal was to offer a valved exhaust package that delivers a unique and aggressive exhaust note without sacrificing a refined cabin experience – from mild to wild at the press of a button. An upgraded downpipe greatly enhances the character of the car, but without a proper rear exhaust it can introduce undesirable drone during normal driving conditions, especially around 3,000 RPM. 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 pairs well with the 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. For the downpipe, smooth mandrel bent piping ranging from 90mm down to 55mm upon exit encourages better throttle response, turbo sound, and an overall more exciting exhaust note.
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. Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked. Back purged TIG welding ensures proper weld penetration and longevity.
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. 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.
HJS CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. The 200 cell design uses a premium wash coat of precious metals to achieve a high level of effectiveness at catalyzing even with the increase in exhaust flow.
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.
BOLT ON AND GO: Each set of Race Pipes is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. New hardware is included for the two bolt flanges. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered with a Lifetime Warranty!
