Our take on the AP Exhaust 642311 Catalytic Converter

The AP Exhaust 642311 is a direct-fit catalytic converter for 1986–1992 Jeep and Dodge models with 2.5L, 3L, or 4L engines. It uses a ceramic substrate with increased precious-metal loading and improved oxygen storage to keep the MIL light off and lower emissions. It suits owners repairing or modifying older off-road Jeeps who want a bolt-on fit without fabrication. Compared with universal converters, it offers vehicle-specific fitment and included hardware, but it is not for OBDII vehicles despite the listing note.
