Our take on the A-Premium Front Exhaust Manifold Catalytic Converter Kit

This is a front exhaust manifold and catalytic converter assembly for the 2006-2008 Hyundai Sonata and Kia Optima with the 2.4L four-cylinder, plus the 2007-2008 Kia Rondo. It replaces the factory manifold-cat unit as one piece, with stainless steel construction, a 7-bolt inlet flange, a 2-bolt outlet flange, and gaskets and bolts in the box. It is a direct-fit federal-emissions part, so it suits owners in most states repairing a failed or rusted original unit. Against a universal weld-in cat, it saves fabrication time; against an OEM dealer part it is a budget alternative, though buyers should expect a shorter service life and check fitment carefully.
