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

The SOUL Performance Valved Exhaust System with Long Tube Street Headers delivers a sophisticated, controlled tone with the valves closed and a signature flat-six wail when the valves open, providing meaningful performance gains without triggering a check engine light. SOUL Performance Long Tube Street Headers are engineered around large-diameter, free-flowing catalytic converters and long-tube runners to maximize power, throttle response, and overall flat-six character. With the valves closed, the system remains ideal for daily driving, keeping volume and drone in check to prevent fatigue. When the valves open, the straight-through flow path unleashes an intoxicating, high-energy soundtrack that exits through the customer’s preferred exhaust tips. SOUL Performance backs this complete exhaust solution with an industry-leading lifetime warranty.

Development

• By developing a unique application for the 981 platform, SOUL Performance focused on properly sizing the 2-inch runners 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 often 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, the SOUL mufflers virtually eliminate droning, keeping the tone controlled with the valves closed even when paired with aftermarket headers.

Construction

• These precision-engineered headers are meticulously fabricated from T304L stainless steel and incorporate proven design features such as port-matched flanges, smooth-radius primary tubing, and optimized collectors that work together to improve exhaust flow and maximize power gains. Each set is rigorously quality-checked prior to shipping. The exhaust system is also constructed from mandrel-bent T304L stainless steel tubing and includes mufflers with fortified casings for enhanced 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.
