Corvette C8 Stingray / Z06 MaxFlow Performance Cats Free-Flow & 200-Cell High-Flow Options | Full Heat-Shielded Construction The Yonristic Performance Cats for the Corvette C8 are engineered to replace the restrictive factory catalytic sections with a high-flow solution designed for maximum exhaust efficiency. By improving flow directly after the headers, the system reduces backpressure and allows the engine to breathe more freely, resulting in sharper response, stronger top-end pull, and a more open exhaust character. For customers seeking the most aggressive setup, the free-flow version delivers the least restriction and the loudest, most race-focused sound profile. For those who want a more balanced configuration, the 200-cell high-flow catted version offers improved flow over the factory cats while maintaining a more refined tone and catalytic structure. Both versions are fully wrapped in high-temperature heat shielding, helping manage radiant heat around the engine bay and rear exhaust area. This is especially important on the C8 platform due to its mid-engine layout, where thermal control plays a major role in component protection and consistent performance under hard driving. Each set includes O2 spacers as a temporary solution to help reduce catalyst-efficiency related warning lights before proper ECU calibration. However, tuning is still strongly recommended for the best performance, drivability, and long-term reliability. This system is built for maximum flow, sound, and performance, making it an ideal upgrade for C8 owners looking to pair it with an aftermarket catback exhaust or full performance exhaust setup.
