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.

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 set 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.

    Soul Performance is the real deal!!! I started researching upgrades for my 2017 911 and kept stumbling across people mentioning Soul Performance on different Porsche Forums and Facebook Groups along with seeing Soul themselves post, answer questions, and interact with others on those same social medium channels. After another friend that wrenches on Porsche recommended them plus the shop that I order my performance parts from also had great things to say about them I decided I had to give their high flow catalytic converters a try.

    The parts were well packed, excellent quality, and fit & finish was perfect. Installation was straight forward and when I had a question Soul performance was available and able to answer it immediately! No CEL lights and a nice bump in performance & sound. I couldn’t be happier with my purchase! I’ve even been in communication with them after my purchase and have been discussing development for a few other exhaust options for my platform.

    The guys at Soul Performance are enthusiast themselves and have been an absolute pleasure to work with. Their customer service and communication are award worthy and should be a benchmark for other companies. You can tell they care, have a passion for performance, and enjoy taking care of their customers!
