Description
Unleash the full potential of your 2025+ Chevrolet Corvette C8 ZR1 with the Fabspeed Motorsport Sport Racing HJS German Catalytic Converters—a no-compromise performance upgrade engineered for maximum power, flow, and sound without sacrificing emissions compliance.
While the factory catalytic system restricts exhaust flow, Fabspeed’s solution features ultra high-flow 200-cell HJS EMITEC tri-metallic catalytic converters, trusted in global motorsports including WEC and IMSA competition. Designed to support up to 1200HP per catalyst, these units flow an impressive 90–92% of a straight pipe, dramatically reducing backpressure and unlocking the true capability of the ZR1’s twin-turbocharged engine.
Constructed from aerospace-grade T304L stainless steel, each system is precision-built using fiber optic laser cutting and back-purged TIG welding for exceptional durability. The system is further enhanced with a double-wall Inconel heat blanket and 2000°F ceramic fiber insulation, ensuring optimal thermal management under extreme conditions.
The result is a significant performance upgrade that delivers faster turbo spool, sharper throttle response, and a deeper, more aggressive exhaust note, all while remaining EPA-compliant and TÜV-approved—eliminating the need to go catless.
