Porsche 981 GT4 / Boxster Spyder / Clubsport SOUL Long Tube Street Headers

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. We chose appropriately sized 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.

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.

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 or answer any questions that you may have.
