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 Sport Catalytic Converters to have the best possible exhaust path with valves open in pursuit of maximum exhaust flow.

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.

CONSTRUCTION:  Each set is assembled out of thick wall .065″ T304L stainless steel, then rigorously quality checked in-house. Smooth mandrel bends and thick flanges ensure product longevity.

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 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 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.

    They’re the best. Loud and burbly but still quiet in standard mode on the PSE. I’m finally able to get decent in-cabin noise with the PSE in sport mode with the windows up!

    I wanted a more aggressive note but not obnoxious – basically closer to a stock 991.1 understanding that there would be “turbo” notes. That is exactly what I got. The Soul cats on the stock muffler sound perfect for me with the added benefit of more HP, no “smell” and less weight. The Soul cats are obviously precision made and have a beautiful finish on them are arrived timely and packed super well.

    Once I got the exhaust off and the original cats off the muffler it I couldn’t get the Soul cats on the muffler because the factory brackets had slightly crushed the muffler pipes. This was easily remedied by taking the muffler to a muffler shop and I had them expand the pipes a bit which they did for free. All I lost was an hour. Everything went back together easily, straight and without fuss from there.

    The above mentioned very minor complications concerned the Soul guys so much that they called and were only above and beyond on how they could be supportive which was funny to me because none of it was really a big deal especially since this was the first time I had ever worked on any Porsche ever…. Obviously they make a first class product and their customer service is terrific. All in all I would highly recommend the product and given 4-6 hours on a Saturday anyone can do this themselves. The key is to take your time and be methodical.

    The best thing though is the sound – wow!

    The Soul guys were fabulous to work with and made the purchase and shipping easy. The cats were extremely well packed and the quality appears top notch. Instructions were detailed and easy to follow. The install is straightforward and really just bolt on. Some of the bolts are however a bit difficult to get to and require a bit of effort to remove/install. I installed them myself and am no master mechanic by any means.

    I have had a prior 991.1 C2 with stock exhaust and then added PSE. I’ve also had a 991.1 C2S with an AWE Switch Patch Exhaust, and currently own a GT4 with stock PSE. The new Soul sport cats on the 991.2 C2S remind me of a cross between the 991.1 stock exhaust and that with the PSE. It definitely takes the sound up a notch and overall increases the quality of the sound while maintaining the turbo characteristics. The burbles sound much better and less manufactured. I believe this is a “must” modification for guys who are used to a Porsche NA exhaust but want the benefits of the new 991.2 cars. I have had such a good experience with Soul that I have ordered a set of headers from them for the GT4 and am looking forward to installing them soon.
