Detailed Description

Davico Exact-Fit Catalytic Converter 17426 is engineered as a direct-fit catalytic converter for rear exhaust placement on select Hyundai and Kia models. It is designed from original equipment sample parts to help ensure proper fit and function, especially on vehicles where the OE converter is a welded assembly that must be cut to fit during replacement.
