DEVELOPMENT AND TESTING: By creating a unique application for the 987.2 platform, we’ve focused on sizing the runners (2”) and collectors correctly to extract maximum power from the 3.4L engine while producing great gains from the 2.9L as well. During dyno testing on a Dynojet, we experienced max gains of 8 whp and 11 ft-lbs of torque at 4,100 RPM when paired with our Valved Exhaust on the Soul project Cayman S with PDK.
CONSTRUCTION: Each header is assembled out of T304L stainless steel and rigorously quality checked in-house. Proven design elements including port matched flanges, smooth radius primary tubing, and collectors that optimize the exhaust flow all work in conjunction to maximize power gains.
HJS CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!
BOLT ON AND GO: Each set of headers is tested in a fixture to ensure perfect fitment. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY: Enjoy your Soul exhaust components with confidence on both the street and track as they are covered for life! Our team will quickly work with you to resolve any issues that you may have. We cover our HJS catalytic converters with an unprecedented 3 year warranty while the headers themselves are backed by our Lifetime Warranty.
