Davico 18427 Catalytic Converter - Center

Exact-Fit Catalytic Converter for Volkswagen SULEV Applications

Davico 18427 is an Exact-Fit Catalytic Converter built from original equipment sample parts to match the factory layout on select Volkswagen center exhaust applications. It uses a high-quality emissions-reducing catalyst for OBDII-equipped vehicles and is listed with two O2 sensor ports, a 4-bolt fixed flange inlet, and a slip-fit outlet.

Compatible With 2005-2014 Volkswagen Jetta, Golf, Beetle, and Passat center exhaust positions, this converter is a direct replacement for SULEV-equipped vehicles where the original unit has failed or emissions performance has declined. Davico 18427 is also referenced as an exact-fit replacement for the same application family.

Product Details

Davico Exact-Fit Catalytic Converters are engineered around factory-style dimensions and connection points so the converter installs in the intended center exhaust location without custom fabrication. This part number, 18427, is designed for Volkswagen models with SULEV equipment and OBDII emissions monitoring, including 2012-2014 Volkswagen Beetle, Golf, Jetta, and Passat center applications, plus earlier Golf and Jetta center applications listed for 2010-2011 and 2005-2011 respectively.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Failed catalytic converter efficiency codes
• Exhaust restriction from a deteriorated converter substrate
• Emissions test failures related to catalyst performance
• Check engine lights tied to O2 sensor and catalyst monitoring
• Factory fit issues caused by damaged or missing OE converter assemblies

Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering. This converter is not legal for use in California and is illegal for installation in New York on vehicles equipped with California emission systems. Confirm the vehicle has 2 O2 ports and matches the center-position fitment listed for your Volkswagen Jetta, Golf, Beetle, or Passat. Gaskets are included, and the inlet/outlet styles should be matched to the existing exhaust connections before installation.

Quality Assurance

Davico builds this Exact-Fit Catalytic Converter from OE sample parts and uses an emissions-reducing catalyst selected for current OBDII vehicle demands. The result is a replacement converter designed to follow factory-style fitment and emissions-system requirements for the listed Volkswagen applications.
