Overview

This Walker Ultra EPA Direct-Fit Catalytic Converter, part number 16577, is an EPA-compliant solution for OBDII vehicles manufactured in 1996 and newer. It features a direct-fit, bolt-on design with OE-style hangers, brackets, routings, and heat shields, ensuring easy installation without the need for specialized fabrication or welding. The converter is engineered with OE-style high-technology wash coat and optimal precious metal load to effectively reduce tailpipe emissions and keep the check engine light off for emissions codes. It boasts strong and durable construction with thick OE-style flanges, hangers, and brackets. When originally equipped, aluminized heat shields are included to protect the undercarriage from converter-generated heat. This product is backed by Walker's 25,000-mile/40,000-kilometer emissions and 50,000-mile/80,000-kilometer structural integrity limited warranty. Please note that it is not legal for sale or use in CA, CO & NY. It is legal in ME on EPA Federal Emission Equipped Vehicles only. Consult your state's aftermarket converter regulations for details. Gaskets and hardware are not included and must be purchased separately or existing hardware can be used.
