DEVELOPMENT: We sought to maximize performance and boost response knowing that incorporating a merge collector would be particularly beneficial to owners seeking maximum horsepower. Our optimized 3 into 1 merge design improves response over the basic factory design (which lacks a collector), while our equal length 1.75″ runners ultimately increase exhaust velocity into the collector and turbo. The factory outlets are different sized between left and right – 1.4″ and 1.8″ ID respectively – while the SOUL outlet is 2.25″ ID allowing for increased flow and support for big power builds. The internal volume of the header combined with the resulting design improvements pairs well with the efficiency map of the turbo giving you noticeably quicker boost response and more power throughout the RPM range. Pushing the gas pedal down commands faster feedback from the car and each gear has more usable power before a downshift.
CONSTRUCTION: Each set is assembled in house in the USA out of laser cut flanges and mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. 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.
BOLT ON AND GO: Every component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition.
CHECK ENGINE LIGHT?: The factory headers do not contain catalytic converters and no check engine light is to be expected with this modification.
