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

SOUL Performance Valved Exhaust with its Long Tube Street Headers delivers a refined, composed tone with the valves closed and a sharp flat-six wail when opened, while improving power and throttle response without a check engine light. Large-diameter, high-flow catalytic converters and long-tube runners maximize performance and enhance engine character. Quiet mode stays daily-driver friendly with minimal drone, while open mode unleashes a full, straight-through soundtrack through the exhaust tips of choice. The setup is backed by SOUL Performance’s industry-leading lifetime warranty.

Development

• By developing a unique application for the 981 platform, SOUL Performance focused on properly sizing the runners (2-inch) and collectors to extract maximum power from the 3.4L engine while still delivering strong gains on the 2.7L. Appropriately sized, high-flow catalytic converters were selected to support maximum power increases and long-term durability, avoiding the compromises associated with smaller, budget catalysts. SOUL Performance also ensured the system delivers a broad sound range, Cup car inspired with the valves open, yet refined and free of drone with the valves closed. In fact, SOUL mufflers virtually eliminate droning, keeping the tone controlled with the valves closed even when paired with aftermarket headers.

Construction

• SOUL Performance precision-engineered headers are meticulously fabricated from T304L stainless steel and incorporate proven design elements such as port-matched flanges, smooth-radius primary tubing, and optimized collectors to improve exhaust flow and maximize power gains. Each set is rigorously quality-checked prior to shipment. In addition, SOUL Performance exhaust systems are constructed from mandrel-bent T304L stainless steel tubing and utilize mufflers with fortified casings to enhance long-term durability.

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.
