DEVELOPMENT & SOUND: The factory header design is a very simple, mass produced component not suited for performance. By creating a unique application for the 991.1 platform, we’ve focused on sizing the runners (2”) correctly to extract maximum power from the 3.8L engine while producing great gains from the 3.4L as well. Flow is enhanced without a check engine light due to our premium SOUL designed and US produced 300 cell catalytic converters with custom specced precious metal catalyst coating and triple metal matrix core.
POWER: Verified independent dyno testing at Apex Autowerks on a Mustang dyno revealed real, repeatable peak gains of 9 whp and 13 ft-lbs of torque with a noticeable improvement in the mid RPM range, well over 25 whp and ft-lbs of torque at 3,000 RPM for a boost where you’ll be at most during normal driving. Even greater power can be realized with an ECU tune, especially after 5,000 RPM where adjusting timing would make a significant difference.
CONSTRUCTION: Each 991.1 header set is assembled out of T304L stainless steel. Merge spikes are incorporated to smooth exhaust flow into the collector and increase power. Thick water jet cut flanges cut to ISO 9001:2015 standards ensure perfect fitment and product longevity. Each exhaust is tested in a fixture to guarantee fitment and then foam packed to ensure they arrive in perfect condition.
BOLT ON AND GO: Each set of catted headers is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment then foam packed to arrive in perfect condition. New high grade hardware is included for the header to exhaust flange. 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 by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.
