25-27+ C8 Corvette ZR1/ZR1X High-Flow Sport Catalytic Converters - Soul Performance

Fits 2025+ C8 Corvette ( ZR1 Models )

Description: 

Unlock enhanced exhaust performance, improved throttle response, and a more aggressive twin-turbocharged V8 exhaust note from your 2025+ Chevrolet C8 Corvette ZR1 or ZR1X with the SOUL Performance Products Sport Catalytic Converters. Available under Part Numbers CHEV.C8.ZR1.SCC and CHEV.C8.ZR1X.SCC, these premium high-flow catalytic converter assemblies are specifically engineered for the 5.5L LT7 twin-turbocharged V8 engine. Designed to replace the restrictive factory catalytic converters, SOUL's proprietary 300-cell sport catalysts feature a triple-metal-matrix core and specialized precious-metal coating to improve exhaust flow while delivering enhanced turbocharger sound and a more pronounced exhaust note. Independently tested on a development vehicle, SOUL recorded gains exceeding 87 wheel horsepower and 106 lb-ft of torque at 4,280 RPM, demonstrating the performance potential of its high-flow downpipe design. Each set is handcrafted in the USA using mandrel-bent, thick-wall T304L stainless steel tubing, Schedule 10 piping ahead of the catalysts, precision back-purged TIG welding, and integrated heat shielding for exceptional durability and thermal management. Weighing approximately 11.9 pounds less than the factory components, these Sport Catalytic Converters provide a premium exhaust upgrade for C8 Corvette ZR1 and ZR1X owners seeking improved performance, enhanced sound, and reduced exhaust system weight. Both model-specific configurations are available directly on this product page, with the ZR1X version featuring additional exhaust gas temperature sensor provisions.
