SOUL Performance Street Long-Tube Headers for 987.2 Porsche Boxster / Cayman

SOUL Performance Products’ Long Tube Street Headers for the Porsche 987.2 Boxster and Cayman are designed around large-diameter, free-flowing HJS HD 200-cell catalytic converters and true long-tube runners to unlock real gains in power, throttle response, and flat-six character, all without triggering a check engine light when used as intended. Optimized 2″ primary runners and collectors are specifically sized for the 987.2’s 3.4L and 2.9L engines, helping the car pull harder through the midrange and up top instead of relying on a generic one-size-fits-all header design. Each set is hand-built from T304L stainless steel with port-matched flanges, smooth-radius primaries, and carefully engineered collectors, then rigorously quality-checked in-house before shipping to ensure long-term durability and a precise seal.The premium HJS HD 200-cell cats are EURO 4-capable and use a robust triple-foil core for outstanding resilience under heat and load, so owners don’t have to compromise between flow, reliability, and emissions efficiency. Designed as a direct bolt-on for all 2009-2012 987.2 Boxster and Cayman models, these headers integrate cleanly with the factory exhaust, weigh about 1.8lb less than stock, and are backed by SOUL’s renowned Lifetime Warranty for street and track use, making them a compelling choice for enthusiasts who want meaningful performance gains and a richer exhaust note without sacrificing everyday usability.

Development & Testing

• SOUL Performance Products took a specialized approach for the 987.2 platform, carefully configuring the sizing of the runners (2″) and collectors to optimize power output from the 3.4L engine while delivering significant gains for the 2.9L variant. Through dyno testing on a Dynojet, they achieved impressive peak gains of 7whp and 8ft-lbs of torque at 4100rpm when combining these headers with their Valved Exhaust system on the SOUL project Cayman S with PDK transmission.

Construction

• Every individual header is meticulously crafted from T304L stainless steel and subjected to thorough in-house quality checks. The design incorporates proven elements such as port matched flanges, primary tubing with smooth radii, and collectors optimized for efficient exhaust flow. These combined features synergistically contribute to achieving maximum power gains.

HJS Catalysts

• SOUL Performance Products incorporates the utmost quality catalytic converters, renowned for their industry-leading flow and exceptional durability. These converters demonstrate impressive efficiency, meeting stringent EURO 4 emission standards while enabling increased flow, all without triggering a check engine light. The HD design utilizes premium triple foil winding to ensure optimal strength. Moreover, the inclusion of a brazing stripe as an additional feature enhances durability, preventing core movement or damage even under sustained high horsepower applications. SOUL Performance Products deliberately utilizes a generously sized catalyst to facilitate maximum gains, leaving no room for compromises in performance.

Bolt On & Go

• Every set of headers undergoes meticulous testing within a fixture to guarantee flawless fitment. Subsequently, they are carefully foam packed to ensure they reach their destination in impeccable condition. Additionally, the package includes comprehensive installation instructions, facilitating a straightforward installation process suitable for most do-it-yourself enthusiasts. Rest assured, the headers come with new, high-grade hardware specifically designed for secure attachment between the headers and exhaust flanges.
