SOUL Performance Competition Headers for 987.1 Porsche Boxster & Cayman

SOUL Performance Products’ Porsche 987.1 Boxster / Cayman SOUL Competition Headers are designed to deliver the greatest gains in power and sound over the heavy, restrictive factory manifolds. By freeing up flow at the source, they help reduce operating temperatures, sharpen engine response, and add a more aggressive tone that stands out without compromising fitment. Each set is precision fabricated from mandrel-bent 14-16ga T304L stainless steel and built around proven design elements like port-matched flanges, smooth-radius primary tubing, and flow-optimized collectors to maximize performance. For a true bolt-on install, every header set is fixture-tested for precise fitment, rigorously quality-checked, then foam packed with installation instructions included. SOUL Competition Headers are also the exclusive, class-legal replacement for the 987.1 Spec Cayman (SPC) series and are backed by SOUL’s lifetime warranty for both street and track use.
