SOUL Performance Competition Exhaust System for 987.1 Porsche Boxster / Cayman

The SOUL Performance Products Competition Package for the 987.1 Cayman and Boxster is engineered by enthusiasts with a focus on unlocking performance where the factory system falls short. The OEM headers feature oversized catalytic converters, thin flanges, and restrictive primary tubing that limit flow and power, while a secondary set of catalytic converters further reduces output downstream. This package addresses those bottlenecks all at once with a fully matched system designed to work in harmony, Competition Headers paired with the Performance Exhaust System. The headers utilize large, long primary tubes feeding into a smooth merge collector, while the exhaust incorporates mandrel-bent over-axle pipes and eliminates the secondary catalytic converters to significantly increase exhaust flow. Fortified, high-flow mufflers deliver a refined yet aggressive tone while keeping drone to a minimum, resulting in sharper responsiveness and a more engaging character from the car.

Construction

• SOUL Performance’s precision-engineered headers are meticulously fabricated from T304L stainless steel and built around proven design elements to maximize power gains. Port-matched flanges, smooth-radius primary tubing, and flow-optimized collectors work together to improve exhaust efficiency. Every set is rigorously quality-checked prior to shipping. Each system is constructed from mandrel-bent T304L stainless steel tubing and features 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.
