Product Description

The CORSA 16234 is a set of high-flow 400 cell catalytic converters engineered specifically for the C8 Corvette's 6.2L V8, designed to replace the restrictive factory cats without sacrificing emissions compliance. Built from 304 stainless steel and CAD-modeled for exact fitment, they bolt directly to either the stock exhaust manifolds or CORSA's own long tube headers.

Each converter is rated to support up to 850 horsepower, giving C8 owners meaningful headroom for future power upgrades while staying EPA compliant and 49-state legal. It's a solid choice for Corvette owners looking to unlock more flow and sound from the exhaust system without going fully catless, and it's backed by CORSA's limited lifetime warranty.
