SOUL Porsche 991 Turbo Sport Headers

DEVELOPMENT:  We sought out to maximize performance and boost response while minding clearance on daily driven cars. Our optimized 3 into 1 merge collector design improves response over the poor factory design, while our runners ultimately increase exhaust velocity into the collector and turbo. Looking into the factory headers you will notice a support in the middle runner which is detrimental to a smooth flow path out of that exhaust port – all in all the design is very basic with lots of room for improvement. The factory turbo inlet measures around 1.54” ID and we sized our header outlet to 1.63” for a smooth flow path into the turbo. 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.

The factory header utilizes a double wall design while our design is single wall yielding in a more pleasing, sharper edge to the exhaust and increased turbo sound. Exhaust volume and tone quality are delightfully increased without yielding drone or undesirable qualities. Expect more burbles and sharper pops between shifts and on deceleration.

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. New high grade hardware and OEM Porsche gaskets are included for installation.

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 issues or answer any questions that you may have.
