Fabspeed HJS Sport Catalysts for Corvette C8 ZR1X (2026+)

Select the dedicated ZR1X HJS catalyst reference only after confirming its original assembly and sensor interfaces. Fabspeed separately states that the ZR1 catalyst kit is not cross-compatible with ZR1X, so the two cannot be substituted by appearance. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.

Before you order

Confirm the dedicated ZR1X catalyst dimensions, supplied contents and installation requirements before ordering. The ZR1 catalyst application is a separate reference.
