Product Description

 

 

The Fabspeed ZR1 Sport Racing Catalytic Converters are a no-compromise exhaust upgrade engineered to unlock the full performance potential of the Chevrolet Corvette C8 ZR1 twin-turbo platform. Utilizing German-engineered HJS 200-cell tri-metallic catalysts, this system flows up to 90–92% of a straight pipe, dramatically reducing backpressure while maintaining emissions compliance.

Designed for extreme horsepower applications, these sport cats are rated for up to 1200HP per catalyst and deliver massive gains in turbo response, throttle sensitivity, and overall power.  The result is a sharper, more aggressive driving experience with faster spool, increased midrange torque, and a more exotic turbocharged sound profile. Built from aerospace-grade stainless steel and insulated for high heat environments, this is a true motorsports-derived solution for drivers who want maximum performance without going catless.
