Exact-Fit Catalytic Converter

Davico catalytic converter part number 250555 is built from original equipment sample parts to match fit and function on the vehicle. It is CARB legal and uses approved cross-marketing agreements with executive order holders for California applications.

  • Exact-fit design based on OE sample parts for proper fitment.
  • CARB legal construction for regulated emissions applications.
  • Includes a 3-bolt loose flange inlet and slide-on outlet connection.
  • Uses two oxygen sensor locations and a supplied inlet gasket reference EG24236.
  • Davico part number 250555 is marked on the converter body with the executive order information.

Detailed Application

This catalytic converter is built for 2000 Cadillac Escalade, left, and 2000 Chevrolet Tahoe, left. Fitment notes call for a split Y pipe modification and identify the OE system as a welded assembly, with left and right assemblies required for full replacement. The 2000 Cadillac Escalade and 2000 Chevrolet Tahoe applications also reference California legality and the listed emissions classification details. Davico 250555 is intended for buyers replacing a converter assembly on these exact applications while keeping the emissions system configuration aligned with the original design.

What It Helps Address

  • Failed or restricted catalytic converter flow.
  • Emissions test concerns tied to a damaged converter.
  • Fitment issues when replacing a welded OE exhaust assembly.
  • Need for a California-legal replacement on listed applications.

Installation Notes

Review the fitment notes before installation, especially the split Y pipe modification requirement and the welded-assembly configuration. Confirm the inlet flange style, outlet connection, and oxygen sensor count against the existing exhaust layout. Because the OE system is listed as a welded assembly, installation planning should account for the left-side application and the matching right-side assembly when performing a full replacement.

Quality Assurance

Davico Exact-Fit Catalytic Converters are engineered from OE sample parts and carry CARB-approved compliance support for the listed California applications. Part number 250555 and the executive order information are displayed on the converter body for identification.
