Product Details

Davico Part Number 17431 is an OE-style catalytic converter replacement for Lexus SC430, GS430, LS430, and GS400 applications listed above. The Exact-Fit Catalytic Converter product line is engineered around original equipment samples so the converter matches the vehicle’s mounting points and exhaust layout, helping simplify replacement on front right, front left, and front positions where specified. This unit uses a 3-bolt fixed flange inlet, a 2-bolt fixed flange outlet, and includes gaskets for the installation interface. It is built without O2 sensor locations and is packaged boxed for service use.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Failed catalytic converter efficiency codes on supported Lexus models
• Restricted exhaust flow from a deteriorated converter substrate
• Exhaust leaks at the converter flange connection points
• Check engine light concerns related to emissions system performance
• Replacement needs after corrosion, cracking, or internal breakdown

Installation Notes and Tips

Confirm the vehicle’s emissions configuration before ordering. This converter is not legal for use in California and is illegal for installation in New York on vehicles equipped with California emission systems. Verify the exact position on the vehicle: front right, front left, or front, depending on the application. Match the flange style and exhaust routing before installation, and inspect adjoining pipes and mounting surfaces for wear or damage. Davico recommends use of Decarbonizing Induction Kit 1540ea with this application.
