SOUL Performance Street Long-Tube Headers for 987.1 Porsche Boxster / Cayman

SOUL Performance Products’ Long Tube Street Headers for the Porsche 987.1 Boxster and Cayman are built around large-diameter, free-flowing HJS 200-cell catalytic converters and true long-tube runners to unlock significant gains in power, throttle response, and classic flat-six character across both 2.7L and 3.4L applications.Optimized 1.75″ primary runners and collectors are specifically sized for the 987.1 platform, with merge spikes in each collector to smooth exhaust flow and help the engine pull harder through the rev range rather than relying on a generic, one-size-fits-all design. Each header set is hand-assembled from T304L stainless steel with thick, water jet cut flanges made to ISO 9001:2015 standards for long-term durability and precise sealing, then rigorously quality checked in-house at SOUL’s Willow Grove, PA facility. The premium HJS 200-cell catalysts offer industry-leading flow and durability while meeting strict EURO 3 efficiency targets, greatly reducing the likelihood of check engine lights compared to lesser cores. Designed as a direct bolt-on for all 2005-2008 987.1 Boxster and Cayman models, these headers integrate cleanly with the factory exhaust, include new hardware, and are backed by SOUL’s renowned Lifetime Warranty for street and track use making them a go-to solution for owners seeking real performance gains without sacrificing reliability.

Development & Sound

• The stock header design is a basic, widely manufactured part that lacks performance capabilities. SOUL Performance Products, however, took a different approach, specifically for the 987.1 platform. They paid close attention to properly sizing the runners at 1.75″ and integrated top-notch spikes into the collectors. This innovative design allows for extracting optimal power from the 3.4L engine while also generating significant gains from the 2.7L variant.

Construction

• Every set of 987.1 headers is meticulously constructed using T304L stainless steel and subjected to thorough in-house quality checks. These headers feature merge spikes that are skillfully integrated to enhance exhaust flow, resulting in heightened power output. Additionally, the headers are equipped with water jet cut flanges that are of substantial thickness and adhere to ISO 9001:2015 standards, ensuring the product’s precise fitment and long-lasting durability.

HJS Catalysts

• SOUL Performance Products utilizes the finest catalytic converters renowned for their exceptional flow and longevity in the industry. These converters possess remarkable efficiency, enabling compliance with stringent EURO 3 emission standards while simultaneously facilitating improved flow. As a result, the likelihood of triggering a check engine light is significantly minimized. The HJS HF design incorporates premium double-foil winding, delivering unparalleled strength and durability.

Bolt On & Go

• Every set of headers with catalytic converters is meticulously constructed and undergoes rigorous testing within a robust aluminum fixture of substantial thickness. This meticulous process prevents any warping issues and guarantees flawless fitment. Additionally, the headers are carefully foam packed to safeguard them during shipping, ensuring they arrive in impeccable condition. The package also includes new, top-grade hardware specifically designed for secure attachment between the header and exhaust flange.
