This part is engineered for the Chevrolet Colorado and GMC Canyon applications listed below, with pre- and post-converter oxygen sensor ports to match the original emissions layout. Walker EPA 14744 is a practical choice when replacing a worn converter on 2015-2016 trucks that require a direct-fit exhaust solution.

Key Features

  • Direct-fit catalytic converter for specific EPA applications
  • Premium-grade construction with a ceramic substrate
  • Round body design with 4-bolt welded inlet flange and 3-bolt welded outlet flange

Detailed Description

Walker EPA 14744 is part of the Walker Ultra Direct-Fit Catalytic Converter line, which is built for import and domestic OBDII vehicles from 1996 and newer. The EPA-focused design supports emissions-system replacement where a direct-fit converter is required, while the round body and welded flange configuration help maintain the original exhaust routing and sensor placement. This part number is commonly referenced for Chevrolet Colorado and GMC Canyon exhaust repairs, and it cross-references AP Exhaust 644106 and Walker Exhaust 52610 for the same application.

Common Repair Uses

  • Replacing a converter with restricted exhaust flow
  • Addressing emissions-related fault codes tied to catalyst efficiency
  • Restoring proper oxygen sensor signal placement
  • Repairing exhaust leaks at the converter connection points
  • Returning the exhaust system to a direct-fit configuration

Installation Notes
