SOUL Performance Street Long-Tube Headers for 981 Porsche Boxster / Cayman

SOUL Performance Products’ Long Tube Street Headers for the Porsche 981 Boxster and Cayman (2013-2016) are engineered around large-diameter, free-flowing HJS HD 200-cell catalytic converters and true long-tube runners to deliver substantial gains in power, throttle response, and classic flat-six sound,all without triggering a check engine light when used as intended. Optimized 2″ primary runners and collectors are sized to extract maximum performance from the 3.4L engines while still producing meaningful gains on 2.7L cars, making this a true platform-specific solution rather than a generic header. Each set is hand-built from T304L stainless steel with port-matched flanges, smooth-radius primaries, and carefully designed collectors to maintain exhaust velocity and flow, then rigorously quality checked in-house before shipping.The premium HJS HD catalysts are EURO 4–capable, using a robust triple-foil core and brazing stripe for exceptional durability under high-heat, high-load use, so you don’t have to compromise between flow and longevity. Designed as a direct bolt-on with detailed instructions, these headers integrate cleanly with the factory system, are backed by SOUL’s renowned Lifetime Warranty (with a dedicated 3-year warranty on the HJS cats), and are intended for off-road / competition use where emissions regulations allow.

Development & Testing

• SOUL Performance Products dedicated its efforts to developing a distinctive application tailored specifically for the 981 platform. The focus was on accurately sizing the runners (2 inches) and collectors to extract the utmost power from the 3.4L engine, while also generating significant gains for the 2.7L engine. To ensure maximum power enhancements, HJS HD 200-cell catalytic converters of the appropriate size were carefully selected. When it comes to power and durability, it is important not to settle for smaller, less expensive catalysts.

Construction

• Every header is meticulously constructed using T304L stainless steel and undergoes meticulous in-house quality checks. The design incorporates proven elements such as port-matched flanges, smooth radius primary tubing, and collectors that optimize the flow of exhaust. These features work in harmony to maximize the gains in power.

HJS HD 200-Cell Catalysts

• SOUL Performance Products utilizes the finest catalytic converters renowned for their exceptional flow and durability, setting a benchmark in the industry. These catalytic converters exhibit efficiency that meets the rigorous EURO 4 emission standards while facilitating increased flow, all without triggering a check engine light. The HD design incorporates premium triple foil winding to ensure optimal strength and an additional brazing stripe is implemented to enhance durability, preventing any movement or damage to the core caused by sustained high horsepower abuse. SOUL Performance Products employs a generously sized catalyst, ensuring no compromises are made in achieving maximum gains.

Bolt On & Go

• Every set undergoes meticulous testing in a dedicated fixture to ensure flawless fitment. Following this, they are carefully foam packed to guarantee their arrival in pristine condition. The package includes comprehensive installation instructions, enabling a straightforward installation process that can be easily carried out by most DIY enthusiasts.
