Corsa 20+ Chevrolet Corvette High Flow 400 Cell Cat Pipes

High-Flow Catalytic Converters

2020–2024 Chevrolet Corvette C8 6.2L V8

Upgrade your C8 Corvette’s exhaust system with these High-Flow Catalytic Converters, engineered to deliver increased exhaust flow, improved sound, and serious performance capability without sacrificing fitment or reliability. Designed to pair perfectly with performance headers and aftermarket exhaust systems, these cats help unlock the true potential of the LT2 platform.

Featuring 3.0" high-flow 400-cell catalytic cores, these converters significantly reduce exhaust restriction while maintaining excellent emissions control. Each catalytic converter is horsepower-rated up to 850 HP per cat, making them ideal for both naturally aspirated and boosted C8 builds. The result is faster exhaust scavenging, sharper throttle response, and a deeper, more aggressive exhaust tone.

Built with durability and heat resistance in mind, these high-flow cats are designed for demanding street and track environments. Precision construction ensures OEM-style fitment on both Coupe and HTC models, allowing for a straightforward installation when upgrading from factory components.
