CORSA's high flow catalytic converters replace the restrictive factory catalysts with a 400 cell CPSI substrate in a compact 4.5 in outside diameter body, flowing up to 9 percent more than stock while keeping the car EPA compliant on 2017 and newer emissions regulations. Each converter is rated to 850 horsepower, 1700 horsepower for the pair, and the proprietary coating tolerates exhaust gas temperatures to 1700 F, which suits forced induction builds. The 304 stainless construction carries a 3.0 in transition cone and bolts directly to the stock C8 exhaust manifold or to CORSA Performance headers, and it mates to either the factory exhaust or a CORSA cat-back system.
