Bosal 079-4185 Catalytic Converter with Integrated Exhaust Manifold - Front

Federal/EPA Direct-Fit Manifold Converter

Bosal BRExhaust 079-4185 is a direct-fit exhaust manifold catalytic converter built for Federal/EPA emissions applications. It combines stainless steel construction with a ceramic substrate and an integrated manifold layout for a bolt-on replacement on select Ford Escape, Mercury Mariner, and Mazda Tribute front positions.

The Premium Load line focuses on OE-style fitment and emissions compliance for vehicles using OBDII monitoring. This configuration places the oxygen sensor locations pre- and post-converter and uses a direct-fit design to simplify replacement on the front exhaust section.

Key Features

• Stainless steel body and construction for corrosion resistance
• Ceramic substrate material for emissions control performance
• Direct-fit, bolt-on inlet and outlet attachment
• Integrated exhaust manifold with catalytic converter
• Pre- and post-converter oxygen sensor locations
• Federal/EPA compliant design for OBDII applications
• Includes mounting hardware
• Part number: 079-4185

Product Details

The Bosal BRExhaust Premium Load Federal / EPA Compliant Manifold Catalytic Converter is engineered for front-position replacement on 2001-2007 Ford Escape, 2001-2006 Mazda Tribute, and 2005-2007 Mercury Mariner applications listed in the fitment data. Its 2.5-inch main piping diameter and 15.5-inch overall length support a direct replacement layout, while the stainless steel body helps resist exhaust heat and corrosion over time. The integrated manifold design reduces the need to source separate manifold and converter components, and the OBDII sensor placement supports proper emissions-system monitoring. Part number 079-4185 is a practical choice for drivers servicing a Ford Escape, Mercury Mariner, or Mazda Tribute front exhaust manifold converter assembly under Federal/EPA requirements.

Common Issues This Part Addresses

• Failed catalytic converter efficiency codes
• Check engine light concerns related to emissions monitoring
• Corrosion or cracking in the front manifold converter assembly
• Exhaust leaks at the manifold-to-converter section
• Replacement needs after emissions test failure

Installation Notes and Tips

This is a direct-fit, bolt-on replacement for the listed front applications, so no cutting, welding, or fabrication is required. Verify the vehicle build date before ordering, especially for 2001-2002 Ford Escape and 2007 Ford Escape or Mercury Mariner applications with split-date notes. Confirm pre- and post-converter oxygen sensor routing matches the original configuration before installation.
