DEVELOPMENT AND TESTING: By creating a unique application for the 981 platform, we’ve 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 whp 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 a custom ECU tune to disable any check engine lights (for track use only).
LIFETIME WARRANTY: Enjoy your SOUL headers with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
