Keep your Jeep's exhaust flowing cleanly with the Walker Exhaust Direct-Fit Catalytic Converter (P/N 16778). This is the right-side converter, built as a direct-fit replacement for the 2016-2024 JEEP WRANGLER, 2018 JEEP WRANGLER JK, and 2020-2023 JEEP GLADIATOR, so it installs in the original converter's exhaust location on the listed applications.
A catalytic converter routes engine exhaust through a coated substrate that converts hydrocarbons, carbon monoxide, and oxides of nitrogen into less-harmful gases before they exit the tailpipe. If a clogged, cracked, or failed original converter is the cause of your emissions problem, this unit replaces it.
Diagnose the underlying cause before replacing, since a converter code can also stem from upstream engine, sensor, or exhaust issues.
