The Walker Ultra EPA 93239 is a universal-fit catalytic converter for OBDII vehicles from 1996 and newer. It uses a ceramic substrate in a stainless-steel body with 3-inch inlet and outlet, and it is weld-on only, so installation means cutting and welding rather than bolting up. It is EPA compliant but not California (CARB) legal, which is the main split against CARB-approved rivals. It suits owners of older Ford and GM trucks and vans doing an OE-style replacement who can weld or have a shop do it.

Owner feedback on Walker's universal EPA converters is mixed. Many report it quiets the exhaust and clears check-engine codes when installed correctly, while others say the universal fit needed extra fabrication and that some units threw efficiency codes soon after install.
Designed to comply with EPA emissions requirements while delivering premium performance and durability with assured compliance, Walker Ultra Universal Catalytic Converters are available for import and domestic OBDII (1996 and newer) vehicles.
