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, subpar collectors and dense catalytic converters – all robbing your high performance Porsche of the sound and performance it deserves. By smoothing the interface between the flange/primary tubes, using smooth radius large diameter bends, and implementing a performance oriented collector with merge spikes, we have 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 (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity – crucial for durability on the track. Our cast head flanges allow for a smooth transition from exhaust ports into the runners. Water jet cut exhaust flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. We fabricate these headers using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.
HJS HD 200 CELL CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse.
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 for life! Our team will quickly work with you to resolve any issues or answer any questions that you may have. We cover our HJS catalytic converters with a 3 year warranty while the headers themselves are backed by our Lifetime Warranty.
