Walker 84484 Catalytic Converter - Rear

Overview

Walker CalCat 84484 is a direct-fit catalytic converter built for specific rear exhaust applications and engineered to meet CARB compliance requirements. It is a fitment-based replacement for select Ford Taurus and Mercury Sable models, with OE-style dimensions and connection points for a precise installation.

Key Features

• CARB-certified replacement converter for regulated emissions applications
• Direct-fit design with a 2-bolt welded flange inlet and pipe connection outlet
• Stainless steel body with a ceramic substrate
• Small oval body shape with OE-style fitment
• Fits 2004-2007 Ford Taurus, rear
• Fits 2004-2005 Mercury Sable, rear

Detailed Description

The Walker CalCat line focuses on direct-fit catalytic converters validated for compliance and built to match the original exhaust layout. Part number 84484 uses a specific fit design, a stainless steel housing, and a ceramic substrate to support proper exhaust flow and emissions control in the intended application. This part cross-references MagnaFlow Exhaust Products (e.g., 5421031) for the same application.

Compatible With 2004-2007 Ford Taurus rear applications and 2004-2005 Mercury Sable rear applications, this converter is a practical replacement when the original unit is no longer serviceable. The 84484 configuration includes a 2-bolt welded flange inlet, pipe connection outlet, and a small oval body profile that follows the OE-style layout.

What It Helps Address

• Failed or inefficient catalytic converter operation
• Emissions test failure related to converter performance
• Check engine light conditions tied to exhaust aftertreatment faults
• Exhaust restriction caused by a damaged or deteriorated converter
• Fitment issues from using a non-specific replacement part

Installation Notes

Fitment notes call for an exhaust gasket and list additional part 31616 as needed to complete installation. This converter uses a direct-fit layout for the specified rear applications, and the outlet connects to pipe rather than a flanged outlet. Verify the vehicle’s engine family and emissions requirements before installation.

Quality Assurance

Walker CalCat 84484 is designed, tested, and validated to meet CARB standards for the listed applications. It is intended for OBDII and non-OBD vehicles within the covered fitment range and carries CARB Executive Order D-182-73 for the specified applications.
