DEVELOPMENT AND TESTING: We set out to increase power and sound without throwing a check engine light. Using HJS HD 200 cell catalysts allows us to do just that. We designed our Porsche 991.2 Carrera (with PSE) Cat Bypass Pipes to have the best possible exhaust path with valves open in pursuit of maximum exhaust flow – no compromises.
POWER: We approached AWE Tuning about testing our development car at their facility for third-party dyno results. We experienced gains of 12 whp and 13 ft-lbs of torque at 4,700 RPM as tested on a 2017 Carrera 4S with no other mods. Peak power was up by 14 whp and 15 ft-lbs. Much greater gains can be expected from the freer flowing exhaust components when paired with a tune.
Porsche 991.2 Carrera (with PSE) Cat Bypass Pipes CONSTRUCTION:
Each set is assembled in-house out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding ensures proper weld penetration and longevity. Each set is tested in a fixture to guarantee fitment and then foam packed to ensure they arrive in perfect condition.
HJS 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 – all without a check engine light. 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. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!
BOLT ON AND GO: Each product is rigorously quality-checked and tested in a fixture to ensure perfect fitment. 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 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 an unprecedented 3 year warranty while the components themselves are backed by our Lifetime Warranty.
