DEVELOPMENT: Arguably the most impactful hardware upgrade on the RS6 / RS7 is replacing the restrictive and heavy factory catalytic converters. Swapping your factory catalytic converters with HJS HD 200 cell catalytic converters – designed to withstand extreme abuse – let you hear your turbos clear as day with no noxious fumes. As a result of the increased flow you’ll enjoy better turbo response and an increase in drivability!
CONSTRUCTION: Each set of sport cats is made in-house by our fabrication team from mandrel bent .065″ wall, 2.5″ diameter T304L stainless steel tubing, CNC cut flanges, and laser cut brackets. All welds are back purged for increased longevity under the most extreme conditions.
HJS HD 200 CELL CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. With their premium wash coat full of precious metals, they are efficient enough at catalyzing to meet strict EURO 4 emission standards while still allowing for an increase in flow. The HD design uses a stout 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 set is built and tested in a thick gauge aluminum fixture (which prevents warping) for perfect fitment – guaranteed. Every set is rigorously quality-checked prior to shipping and then foam packed to ensure they arrive in perfect condition. New high-grade hardware is included.
CHECK ENGINE LIGHT?: This product may trigger a check engine light due to removal of factory catalytic converters. 2020+ models of many marquees have become extra sensitive to alterations in the exhaust stream.
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.
