Davico 48099 Catalytic Converter - Rear

Dealer Alternative Catalytic Converter

Davico 48099 is a dealer alternative exact-fit catalytic converter built for emissions service on select Toyota and Lexus applications. It uses OEM-style wash coat technology, larger substrates, and increased oxygen storage capacity to address high-mileage and maintenance-sensitive exhaust systems.

Key Features

• Dealer Alternative Exact-Fit Catalytic Converter line for direct replacement applications.
• OEM-style wash coat technology with precious metal loadings.
• Larger substrate design for greater oxygen storage capability.
• Cataloged for vehicles that are sensitive to mileage and maintenance-related emissions issues.
• Davico 48099 is built for exhaust system service where OE-style fitment is required.

Detailed Description

This catalytic converter is engineered for rear exhaust placement on 1999-2001 Lexus ES300 and 2000-2004 Toyota Avalon applications. The Davico Dealer Alternative Exact-Fit Catalytic Converter line is positioned as an alternative to OE replacement converters, using substrate and wash coat construction intended to address emissions performance on vehicles affected by age, mileage, or poor maintenance. Part number 48099 is listed for rear fitment on the Toyota Avalon and Lexus ES300, and the fitment notes specify emissions-use restrictions for California and New York vehicles equipped with California emission systems.

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

What It Is Used For

• Restoring exhaust after catalyst efficiency declines.
• Addressing emissions-related fault codes tied to converter performance.
• Replacing a worn or contaminated rear catalytic converter.
• Supporting exhaust service on high-mileage vehicles.

Installation Notes and Tips

Fits 2000-2004 Toyota Avalon, rear. Fits 1999-2001 Lexus ES300, rear. Gaskets are not included.
