Product Description

The MagnaFlow 280120 OEM-Grade Direct-Fit Catalytic Converter is designed as a one-to-one replacement for the factory converter on select Honda 1.5 L I4 vehicles (Civic, Accord, CR-V) spanning model years roughly 2016 through 2022. With a heavy-duty stainless-steel housing and mandrel-bent design, this converter ensures optimal exhaust flow while maintaining emissions compliance under Federal/EPA standards (non-CARB). The integrated O2 sensor port and bolt-on flange connections allow for direct installation with minimal adjustments - ideal when the original converter has failed, clogged, or triggered emissions faults.

Engineered to meet or exceed OEM specifications, the 280120 unit restores proper catalytic function and helps maintain emissions integrity, fuel efficiency, and overall engine performance. Its durable stainless-steel construction and exact-fit design make it a long-lasting replacement - especially valuable for owners needing to replace worn or rusted OEM components without compromising exhaust layout or requiring custom fabrication.
