High Output GREEN Catalytic Converters
Kooks High Output GREEN catalytic converters are engineered for higher horsepower applications and use a 304 stainless steel outer body for strength and durability. Each converter features a high-capacity 300-cell metallic substrate measuring 4-1/2 inches in diameter, providing a performance-oriented catted solution for modified Corvette applications.
OEM-Style Connection
The flanged inlet is designed to connect directly to the factory exhaust manifolds or compatible Kooks headers, while the outlet connects directly to the OEM cat-back exhaust. This configuration makes it possible to upgrade the catted connection section while retaining the factory-style exhaust routing.

The system uses the stock bolt pattern and includes the gaskets and bolt kit required for installation. Vehicle tuning is required after installation, so the appropriate calibration should be completed as part of the upgrade.
