AP Exhaust 771139 CARB Compliant Direct Fit OBD-II Manifold Catalytic Converter

The AP Exhaust 771139 is a direct-fit, OBD-II-specific manifold catalytic converter engineered to meet or exceed original equipment performance and emissions standards. Built under the CATCO line, this converter is fully CARB-compliant, making it street-legal in California and other states that follow California Air Resources Board (CARB) emissions regulations.

Designed specifically for OBD-II equipped vehicles, the 771139 features AP's "Clean By Design" ceramic substrate technology with increased precious metals loading and improved oxygen storage and release for maximum pollution reduction and long-term emissions efficiency. The converter's larger total substrate size and optimized substrate chemistry deliver superior light-off performance and lower emissions output while keeping the MIL (Malfunction Indicator Lamp) light off.
