Exact-Fit Catalytic Converter

Davico 299156 is an exact-fit catalytic converter built from original equipment sample parts to match factory fit and function. It is CARB legal and identified for California applications, with executive order and part number markings on the converter body.

Compatible with Ford E-250 and Ford E-350 Super Duty applications, this converter is built for the right-side exhaust position and the listed 2004-2006 configurations. The Davico 299156 also reflects the brand's split Y pipe modification requirement for the covered applications.

Detailed Description

Davico 299156 is a catalytic converter for Ford E-250 and Ford E-350 Super Duty models that require a right-side replacement in the 2004-2006 range. The converter is engineered around OE sample parts so the fit and function align with the original exhaust layout, and the body carries the executive order and part number identification required for CARB-approved use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

The inlet uses a 2-bolt loose flange and the outlet is a slip fit, with provisions for two oxygen sensors. The product line also notes a split Y pipe modification requirement, so it is important to verify the exhaust configuration before installation on the Ford E-250 or Ford E-350 Super Duty.

What It Helps Fix

  • Failed catalytic converter efficiency codes.
  • Restricted exhaust flow from a worn converter.
  • Emissions test failures tied to converter performance.
  • Exhaust leaks at the converter connection points.
  • Fitment issues when replacing the original welded assembly.

Installation Notes and Quality

Confirm the vehicle's exhaust configuration, including the 4-converter Y-pipe system and the split Y pipe modification requirement, before installation. Gaskets are not included. Use Davico decarbonizing induction kit 1540ea when specified for the application.

Davico designs Exact-Fit Catalytic Converters from OE sample parts and supplies CARB-approved products for regulated applications. The converter body displays the executive order number and part number for identification.

Product Line Note

Davico's Exact-Fit Catalytic Converter line focuses on direct replacement geometry and emissions compliance for covered applications. The line is built to match factory exhaust routing and to support California-legal replacement needs where approved.
