DEVELOPMENT & SOUND: The factory header design is a very simple, mass produced component not suited for performance. By creating a unique application for the 987.1 platform, SOUL focused on sizing the runners (1.75”) correctly and incorporated high quality spikes into the collectors to extract maximum power from the 3.4L engine while producing great gains from the 2.7L as well.
CONSTRUCTION: Each 987.1 header set is assembled out of T304L stainless steel and rigorously quality checked in-house. Merge spikes are incorporated to smooth exhaust flow into the collector and increase power. Thick water jet cut flanges cut to ISO 9001:2015 standards ensure perfect fitment and product longevity.
HJS CATALYSTS: SOUL uses the highest quality catalytic converters available, known for their industry–leading flow and durability. They are efficient enough to meet strict EURO 3 emission standards while still allowing for an increase in flow while greatly reducing the chance of getting a check engine light. The HJS HF design uses premium double foil winding for exceptional strength and durability.
BOLT ON AND GO: Each set of catted headers is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition.. New high grade hardware is included for the header to exhaust flange.
