DEVELOPMENT AND TESTING:  HJS HD 200 cell catalytic converters increase power and turbo sound but the volume is still rather reserved due to the restrictive factory rear exhaust. We set out to craft a rear exhaust that was simple, light, and as aggressive as possible while retaining drivability. The 991.2 non-PSE equipped cars are prone to droning in the 1,800-2,200 RPM range with aftermarket exhausts – the primary factor that we based our system around. We tested numerous variants incorporating resonators, helmholtz resonators / anti-drone tubes, straight pipes, and a basic x-pipe to hone in on the best possible solution. Resonators reduced the overall engine tone and volume and did not have enough of an impact on the drone. Helmholtz resonators (also known as anti-drone tubes) are an effective way to reduce undesirable frequencies when engineered and utilized correctly. Our final design has proven to offer the very best results on this application and achieved our high standards for sound quality and drivability. You’ll be please with the aggressive yet civil nature of this exhaust and enjoy every minute behind the wheel!

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 – 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!

CONSTRUCTION:  Each component is assembled in house out of mandrel bent, thick wall .065″” T304L stainless steel, then rigorously quality checked in-house. Back purged TIG welding ensures proper weld penetration and longevity.

BOLT ON AND GO:  Each product is tested in a fixture to ensure perfect fitment then foam packed to ensure it arrives in perfect condition.

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.

    Just wanted to chime in with my experiences with John G, Oliver, and the rest of the Soul gang. I can’t say enough great things about them! John and I have been chatting about my car, and general opinion of performance, and emotion during the time of ownership. I mentioned that it was a base non-PSE and could def use something extra, and he was gracious enough to schedule some time with me to drive to their location for meet, tour, and install!

    Long story short, the folks there are phenomenal; entertaining all my random questions and being patient with me as one would with a kid in a candy store I need not say much about the product either – it’s true to it’s name, def gives the car a lot of soul! Like I told John, they’re not in the performance parts business, they’re in the happiness business – give them a shot, you will be happy!

    installed a full Soul system last week. Self install with the help of other posts on Rennlist. I would say the job was a 6.5 out of 10, with 10 being pulling the motor. With right tools and tall jack stands, it can be done in home garage. All in I spent 3 night, three hours a night, taking my time (its winter now so no hurry). Nothing tricky and even the heat shield bolts were not that big of an issue

    Disclaimer- Sound is subjective, I cant tell you my mild is your loud. Listen to youtube or better yet, listen to someone that has these parts installed

    I dont have a recording to share but I can say I was pleasantly surprised by the tone/sound of the 3 components working together. Cold start is LOUD but after that, very reasonable. In regular mode it has a nice deep tone, city driving give a few pops and crackles, turbo whistle is evident every time you hit the gas. Sport Mode, tone gets better and pops become more pronounced. ZERO drone, seriously, nada. It has been written that it takes a few hundred miles to break in the pipes/tune. Right now, it is music to my ears. in normal mode, I tried several hands free calls and I hand no problem with sound nor did the person on other end of call. I rarely write reviews but I have to say, I am very pleased with the sound the 4S is making, Was not looking for performance gains, was looking for something that sounded like my old 993. While it will never replicate the NA sound, this package make the water cooled engine sound so much better than stock
