Davico 19391 Catalytic Converter - Rear

Exact-Fit Catalytic Converter

Davico Exact-Fit Catalytic Converter 19391 is built from original equipment sample parts to match fit and function on the vehicle. It uses a high-quality emissions-reducing catalyst for OBDII applications and is configured with 2-bolt fixed flanges at the inlet and outlet.

Key Features

• Exact-Fit design based on OE sample parts for proper fitment.
• Emissions-reducing catalyst formulated for OBDII vehicle demands.
• 2-bolt fixed flange inlet and outlet connections.
• 48.75-inch overall length for application-specific exhaust routing.
• Uses two oxygen sensor provisions.

Detailed Description

This Davico catalytic converter is engineered for rear exhaust placement on Lexus ES350, Toyota Avalon, and Toyota Camry applications. The 19391 part number identifies an Exact-Fit converter that follows OE-style dimensions and connection points, helping maintain proper exhaust flow and emissions control on compatible OBDII systems. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a restricted or inefficient catalytic converter.
• Restoring emissions system performance after catalyst failure.
• Addressing exhaust leaks at flange connections.
• Correcting OBDII catalyst efficiency faults tied to the converter.
• Matching an application-specific rear exhaust layout.

Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering, since this part is not legal for use in California and is illegal for installation in New York on vehicles equipped with California emission systems. Confirm flange style, oxygen sensor count, and overall length against the existing exhaust assembly before installation. The Davico 19391 is intended for rear-position applications on the listed Lexus and Toyota models.

Quality Assurance

Davico uses original equipment sample parts as the basis for fit and function, and the converter is built with emissions-reducing catalyst material for current OBDII requirements.
