SOUL Performance Sport Cats for C8 Chevrolet Corvette Stingray [CHEV.C8.SCC]

SOUL Performance high-flow HJS 200-cell sport cats for 2020+ C8 Corvette that cut backpressure, add power and V8 character, reduce weight, control heat, and stay CEL-free.

The SOUL Performance C8 sport cats replace the restrictive factory equipment on the Chevrolet Corvette with premium HJS HD 200-cell units housed in thick-wall.065″ mandrel-bent T304L stainless assemblies, freeing up the LT2’s V8 rumble, throttle response, and power without sacrificing drivability or triggering check engine lights. Developed as direct bolt-on upgrades for 2020+ C8 models (with or without NPP, and including E-Ray), each set drops roughly 9.6lbs versus the OEM hardware while delivering independently verified gains of 17whp and 20ft-lb of torque when paired with the factory valved exhaust. The converters are TIG welded in-house using robust aluminum fixtures to prevent warping and ensure repeatable fitment, then paired with bespoke PTP Lava heat shields to control underbody temperatures around sensitive components. Supplied with new genuine GM gaskets, rigorously quality-checked, fixture-tested, and foam packed for safe arrival, these sport cats offer a clean, emissions-conscious way to wake up your C8’s sound and performance, all backed by SOUL Performance’s renowned Lifetime Warranty for street and track use.

• Meticulously assembled in-house in the USA using mandrel bent, thick wall.065″ T304L stainless steel. To ensure proper weld penetration and longevity, back purged TIG welding techniques are employed. SOUL Performance takes great care during fabrication by utilizing thick gauge aluminum fixtures, which act as efficient heat sinks during the welding process. This not only prevents warping of their products but also maintains the integrity of the fixtures themselves, guaranteeing a perfect fitment. This is the fabrication standard behind every set of SOUL Performance C8 sport cats
• Considering the proximity of the sport cats to sensitive components, it is crucial to have heat shields in place for the C8 Corvette. To provide a superior heat shielding solution, SOUL Performance has partnered with PTP Turbo Blankets. The bespoke heat shields offered by PTP are custom-made and form-fitting to suit the specific requirements of the C8. These heat shields, constructed with an outer layer made from pulverized volcanic lava rock (rated 1800°F for direct heat and 2500°F for radiant heat), are woven into a tight mesh weave fabric. Internally, they are insulated with high-temperature calcium magnesium silicate wool (rated 1832°F continuous and 2300°F peak), overlaid with a high-temperature stainless steel mesh. This design ensures increased durability and improved thermal resistance. The PTP Lava Turbo Blankets are engineered to withstand the most challenging conditions, offering unparalleled performance and protection.

• The catalytst utilized are the epitome of quality, renowned for their unrivaled flow characteristics and exceptional durability. These converters feature a premium wash coat infused with precious metals, allowing them to efficiently catalyze and meet stringent EURO 4 emission standards, all while permitting increased flow without triggering a check engine light. The HD design incorporates a robust triple foil winding, ensuring maximum strength and resilience. An additional feature, the brazing stripe, is included to enhance durability by preventing core movement or damage from sustained high horsepower abuse.
• The utilization of a large and precisely sized catalyst enables the achievement of maximum gains. These catalysts have undergone extensive testing and have been proven effective in high-performance applications, such as McLaren and Porsche Turbo, where substantial horsepower support is required.

• Third-party testing was conducted at Dynosty on a Dynojet Dyno to assess the performance impact. The baseline power measurements, using the factory exhaust, recorded 453whp and 427ft-lbs of torque. Upon incorporating the SOUL Sport Catalytic Converters, the power increased to 470whp and 447ft-lbs of torque, resulting in remarkable peak gains of 17whp and 20ft-lbs of torque. These are the verified gains buyers can expect from the SOUL Performance C8 sport cats in stock form.

• Every individual product undergoes meticulous quality checks to ensure the highest standards are met. Additionally, each product is thoroughly tested in a fixture to guarantee precise fitment. To ensure their arrival in impeccable condition, they are carefully foam packed for secure transportation. Moreover, to provide a comprehensive solution, new and genuine GM gaskets are included with each product.

PTP Turbo Blankets – Every PTP Turbo Blanket is hand-crafted in North America and quality is guaranteed. PTP Turbo Blankets are well known in the industry for their high standards for material selection, design, construction, and also for their ability to provide these high quality products at an affordable price. It is important to note that, as unfortunate as it is, there are many imitation turbo blankets out there, often made in China. These imitation turbo blankets are manufactured using much inferior materials for construction. Imitation turbo blankets can be ineffective or worse, they can be dangerous if flammable materials are used. PTP Turbo Blankets and wraps are the result of years of product research and development. The exact same materials that are used in their turbo blankets and wraps are currently being used in multiple military applications. Their materials are on the cutting edge of heat insulation technology, for more information see this full research paper here.
