The direct-fit layout helps maintain the original exhaust routing and connection style, which is important when matching the factory exhaust configuration.

Common Replacement Reasons

• Failed emissions testing or catalyst efficiency codes.
• Exhaust restriction that affects engine performance.
• Physical damage to the converter body or flanges.
• Corrosion at the exhaust connection points.
• Need to restore proper exhaust after converter deterioration.

Installation Notes and Tips

Verify the inlet and outlet flange style, O2 sensor count, and overall length before installation.
