You’ll notice the weight savings, decreased operating temperatures and improved engine response – all beneficial on the street or track. This header was designed to extract maximum power from the incredible 3.8L engine and add more of the incredible high-strung flat six symphony that the GT4 is known for.
+ Fits all 981 Porsche GT4 / Boxster Spyder vehicles (2015-2016)
+ Direct bolt on installation – instructions included
+ Power gains of over 20whp
+ All Soul Performance Products are backed by our Lifetime Warranty for both street and track use
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 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 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 that you may have.
