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

The SOUL Performance Products Performance Exhaust System for the Porsche 981 GT4, Boxster Spyder, and Clubsport delivers a refined, sporty flat-six tone with enhanced response and character while minimizing unwanted drone for everyday usability. Built as a valveless, high-flow alternative to the stock Porsche Sport Exhaust, it offers a deeper, richer soundtrack that’s louder than factory with valves open yet retains a balanced and engaging exhaust note fit for street or track use. Precision mandrel-bent T304L stainless steel tubing with 2.5″ OD over-axle pipes and fortified mufflers ensure durability and long-term performance, with high-quality sound-deadening materials inside the mufflers to smooth resonance and refine tone. Multiple exhaust tip styles and finishes are available to complement the rear aesthetics of your 981 GT4. Installation is direct bolt-on with comprehensive instructions included, making this exhaust a straightforward upgrade for enthusiasts seeking improved sound, throttle response, and overall character without sacrificing daily driveability. All SOUL Performance components are backed by a lifetime warranty for both street and track use.

Development

• Following the success of its Valved Exhaust and its proven ability to combat drone, SOUL Performance developed a lighter, valveless exhaust system that delivers 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 notably greater than the factory Porsche Sport Exhaust with valves open, yet retains a refined, well-balanced tone. It is also well suited for track-focused applications requiring maximum exhaust flow while remaining mindful of decibel limits, with highly effective mufflers that suppress drone and promote a fuller, more robust exhaust note 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 features mufflers with fortified casings for enhanced durability. SOUL Performance mufflers are packed with high-quality sound-deadening material engineered to withstand extreme use without blowing out over time. To complement the rear aesthetics of the 981 GT4, a variety of single-wall and double-wall exhaust tip options are available, with optional titanium single-wall tips that reduce weight by nearly one pound compared to stainless steel.

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.
