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

The SOUL Performance Valved Exhaust System for the Porsche 981 GT4, Boxster Spyder, and Clubsport elevates the iconic flat-six soundtrack with a dynamic, tunable tone and enhanced performance without compromising street-friendly manners. Built around high-quality valved mufflers and precision mandrel-bent T304L stainless steel tubing, this system delivers a refined, sporty exhaust note with the valves closed and a thrilling, aggressive voice when the valves open, letting drivers enjoy both civilized cruising and breathtaking back-road character. In quiet mode, the valves keep the tone controlled and drone-free at highway speeds, allowing discreet neighborhood cruising. Open the valves and the system releases the full potential of the 3.8L engine, creating a commanding exhaust soundtrack that enhances every blip and downshift. Designed to integrate seamlessly with the factory valve controls, it maintains usability and convenience for daily driving while offering exhilarating performance potential for spirited driving and track days. Constructed for durability and longevity, the exhaust features 2.5″ over-axle piping and fortified mufflers packed with high-quality sound-deadening material to minimize unwanted resonance and maximize tone quality. Finished with polished chrome dual wall tips, this system adds a bold and premium visual upgrade to the rear of the GT4 or Spyder. Backed by SOUL’s renowned lifetime warranty for both street and track use, it’s a complete exhaust solution that enhances sound, character, and performance.

Development

The GT4 is a masterfully engineered machine from Porsche, with its 3.8L flat-six producing a distinctive wail that begs to be amplified. SOUL Performance developed its Valved Exhaust System to extract the full sonic potential of the GT4 while preserving everyday streetability. With the valves closed, the system delivers a refined, sporty tone with no drone at highway speeds, even when paired with factory or high-flow catted headers, allowing for quiet neighborhood driving thanks to the effectiveness of the high-quality mufflers. Recognizing that many owners run headers on the street, minimizing drone was a key development priority. Open the valves, and the exhaust transforms the driving experience, encouraging windows down, radio off, and full engagement on back roads or at the track, with every downshift producing a sharp, exhilarating bark that underscores the GT4’s performance character.

Construction

Each system is constructed from precision mandrel-bent T304L stainless steel tubing, including 2.5-inch OD over-axle pipes, and incorporates mufflers with fortified casings to ensure long-term durability. With the valves closed, exhaust gases are routed through the SOUL Performance mufflers, which are packed with high-quality sound-deadening material engineered to withstand extreme use without blowing out over time, resulting in exceptional drone suppression. Exhaust gases pass through the muffler and exit via perforations into the outer piping, maintaining a controlled, refined tone. When the valves are open, exhaust gases are free to exit through large 2.5-inch piping, while the perforated design allows the gases to interact with the muffler, promoting a fuller, more robust exhaust note. SOUL Performance offers a wide selection of 321 stainless steel exhaust tips in various styles and finishes, with custom options available upon request. Optional titanium single-wall tips are also offered, reducing 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.
