A’PEXi Super Catalyzer – Toyota GR Corolla GZEA14H

The A’PEXi Super Catalyzer is a high-performance catalytic converter system developed specifically for the Toyota GR Corolla GZEA14H equipped with the turbocharged G16E-GTS engine.

Designed to reduce one of the major restrictions within the factory exhaust system, the A’PEXi Super Catalyzer uses a high-flow metal catalytic core to improve exhaust gas flow and reduce back pressure while retaining catalytic converter functionality.

The reduced exhaust restriction helps improve exhaust efficiency and turbocharger response, making the Super Catalyzer an ideal upgrade when combined with A’PEXi’s N1 Evolution Extreme exhaust system.
