DEVELOPMENT AND TESTING: The factory headers were designed to be easy and cheap to manufacture while also conforming to the performance killing emissions standards of the market.
The stock headers use cheap pressed flanges, squashed primary tubing, generic collectors and massive catalytic converters – all robbing your high performance Porsche of the sound and performance it deserves.
By smoothing the interface between the flange and primary tubes, using smooth radius, large diameter bends, and implementing a performance oriented collector with merge spikes, SOUL has been able to achieve increased flow, response, and performance with a more aggressive exhaust note to match.
CONSTRUCTION: Each set is assembled in house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding ensures proper weld penetration and longevity – crucial for durability on the track.
Water jet cut flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision.
SOUL fabricates these headers using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping.
CHECK ENGINE LIGHT?: This product will likely trigger a check engine light due to removal of factory catalytic converters.
BOLT ON AND GO: Every set is rigorously quality-checked prior to shipping and then foam packed to ensure your order arrives in perfect condition.
New high grade hardware and OEM three bolt gaskets are included.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by a lifetime warranty.
