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.
Third party dyno testing on a Dyno Dynamics dynamometer revealed gains of 40 wheel horsepower when paired with a tune, with 20 whp gains unlocked by Competition 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.
BOLT ON AND GO: Each header is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition.
Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
CHECK ENGINE LIGHT?: This product may trigger a check engine light due to removal of factory catalytic converters.
O2 spacers are available to reduce any chances of triggering a CEL. We suggest an ECU tune to disable any check engine lights (for track use only).
