SOUL Performance Exhaust System with Tips for 981 Porsche Boxster Spyder / Cayman GT4

The SOUL Performance Exhaust System for Porsche 981 GT4, Boxster Spyder, and Clubsport transforms your Porsche’s exhaust character with a more aggressive, refined tone and enhanced performance without sacrificing driveability. Designed as a valveless, high-flow alternative to the factory Porsche Sport Exhaust (PSE), this system delivers a deeper, richer flat-six soundtrack that is significantly louder than stock with valves open, yet engineered to minimize unwanted rasp and harsh drone. Constructed from precision mandrel-bent T304L stainless steel with 2.5” over-axle piping and fortified-cased mufflers, the system is built for longevity on both street and track. High-quality sound-deadening materials within the mufflers smooth out resonance, encouraging a robust, performance-oriented tone that complements aftermarket headers and other upgrades. Multiple tip styles and finishes are available to suit your aesthetic preference, with straight or slash cut single wall tips providing a clean, high-end look. Installation is straightforward with direct bolt-on fitment and comprehensive instructions included, making this exhaust an ideal upgrade for enthusiasts seeking improved sound, character, and throttle response without compromising daily usability. Backed by SOUL’s renowned lifetime warranty, it’s a durable and exciting performance enhancement for your 981 GT4 or Spyder.

Development

• Building on the success of its Valved Exhaust and its proven ability to control drone, SOUL Performance developed a lighter, valveless exhaust system designed to deliver an invigorating exhaust note at all times—mirroring the open-valve character of the Valved Exhaust—while minimizing undesirable traits such as droning and rasp. Engineered for enthusiasts seeking an aggressive sound to complement aftermarket headers without becoming overbearing, the system produces a volume level noticeably greater than the factory Porsche Sport Exhaust with valves open, yet retains a refined, balanced tone. It also serves as an ideal solution for track-focused cars requiring maximum exhaust flow while remaining mindful of decibel limits, with highly effective mufflers that suppress drone and promote a fuller, more robust sound befitting of a Porsche.

Construction

• Each system is constructed from precision mandrel-bent T304L stainless steel tubing, including 2.5-inch OD over-axle pipes, and is equipped with mufflers featuring fortified casings for long-term durability. SOUL Performance mufflers are packed with high-quality sound-deadening material engineered to withstand extreme use without degrading or blowing out over time. To tailor the visual finish, multiple exhaust tip options are offered for the 981 GT4, including a range of single-wall and double-wall designs, with optional titanium single-wall tips that reduce weight by nearly one pound compared to stainless steel alternatives.

Bolt On and Go

• Each SOUL Performance exhaust is test-fit in a dedicated fixture to verify proper fitment, then foam packed to help ensure it arrives in perfect condition. Detailed installation instructions are included for a straightforward install that most DIY enthusiasts can complete. Valve operation is controlled through the factory valve button, SOUL’s valve controller fobs, and is compatible with HomeLink.
