Fabspeed 2023+ Chevrolet Corvette C8 Z06 HJS 200-Cell Sport Catalytic Converters

+28 WHP | +28 LB-FT TQ | -9 LBS
Unleash more of the C8 Z06’s 5.5L LT6 flat-plane-crank V8 with the Fabspeed HJS 200-Cell Sport Catalytic Converters. Engineered specifically for the Z06, these direct-replacement Sport Cats use genuine German-made HJS 200 CPSI tri-metallic catalysts with enlarged exhaust piping to increase flow, sharpen the exhaust note, and improve performance while retaining catalytic converters.
Unlike the Sport Cats designed for the standard C8 Stingray, the Z06 version utilizes a larger catalyst specifically packaged for the Z06 application, taking advantage of the available space to increase catalyst size and exhaust-flow capability.

Genuine HJS 200-Cell Catalytic Converters
The system uses German-made HJS 200-cell EURO 6 EC-certified tri-metallic catalytic converters. Fabspeed increased the piping size on both the engine side and exhaust side of the catalysts to reduce restriction and improve exhaust flow.
These are not the same catalysts used in Fabspeed's standard C8 Stingray Sport Cats. Fabspeed specifically developed the Z06 version around a larger catalyst to provide greater surface area and flow capability for the higher-output LT6.
Performance
The freer-flowing 200-cell catalyst design helps reduce the restriction created by the factory catalytic converters, allowing the LT6 to breathe more efficiently.
Fabspeed rates the system for gains of:
+28 WHP+28 LB-FT TQ-9 LBS
These are manufacturer-published performance figures for the C8 Z06 Sport Cats.
Exotic LT6 Sound
The Sport Cats significantly increase the presence of the Z06's flat-plane-crank exhaust note while retaining catalytic converters.
Fabspeed describes the resulting sound as higher pitched and substantially louder, with a rawer character as the LT6 approaches the upper end of its RPM range. Pops and burbles are also noticeably enhanced.
Direct Bolt-On Installation
The Sport Cats are engineered as a direct bolt-on replacement for the factory C8 Z06 catalytic converters, allowing the factory components to be replaced without requiring a custom exhaust system.
Professional installation recommended.
Warranty
Backed by the Fabspeed Lifetime Warranty. The system uses genuine HJS catalytic converters supplied through Fabspeed.
