DEVELOPMENT AND TESTING: By creating a unique application for the 981 platform, SOUL focused on sizing the runners (2”) and collectors correctly to extract maximum power from the 3.8L engine.
They chose appropriately sized HJS HD 200 cell catalysts to flow enough power for sustained high RPM use – where the GT4 is at home.
Don’t settle for smaller, cheaper catalysts when power and durability is concerned. Third party dyno testing on a Dyno Dynamics dynamometer revealed gains of 30 whp when paired with a tune, with 12 whp gains unlocked by Street Headers alone after the tune had been applied.
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.
SOUL uses a larger yet appropriately sized catalyst to allow for maximum gains – no compromises here!
BOLT ON AND GO: Each product 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.
