OE-Style Direct-Fit Catalytic Converter

AP Exhaust 644136 is a Federal / EPA direct-fit catalytic converter built for specific Volkswagen applications. It uses a stainless steel body, a ceramic substrate, and OE-style dimensions to support proper exhaust flow and emissions control on the listed vehicles.

Compatible With 2010-2014 Volkswagen Jetta, 2012-2014 Volkswagen Beetle, 2012-2014 Volkswagen Golf, and 2012-2014 Volkswagen Passat, this converter is built for direct replacement service where the original unit has failed or no longer meets emissions requirements.

Key Features

  • Federal / EPA direct-fit catalytic converter
  • Stainless steel body for corrosion resistance
  • Ceramic substrate material
  • 4-bolt welded inlet connection
  • 2 1/4" OD outlet connection
  • Two O2 sensor ports
  • Overall length: 40 inches
  • Inlet hardware and outlet hardware included

Built for OE Fitment

AP Exhaust 644136 is engineered with automated manufacturing, spinner welding, and high-speed production processes to maintain OE dimensions and consistent fitment. The ARISTO substrate chemistry is used to support efficient catalyst loading and converter performance while helping control production cost. This makes it a practical replacement for Volkswagen Jetta, Volkswagen Beetle, Volkswagen Golf, and Volkswagen Passat models listed in the fitment data.

This part cross-references 5C0253059AL for the same application.

What This Converter Helps Address

  • Failed catalytic converter efficiency codes
  • Exhaust odor caused by a worn catalyst
  • Restricted exhaust flow from a damaged converter
  • Emissions test failure on the listed Volkswagen applications
  • Exhaust leaks at the converter connection points

Installation Notes

Verify exact vehicle application before installation, including emissions family and state restrictions. This converter is listed for direct-fit service on 2010-2014 Volkswagen Jetta, 2012-2014 Volkswagen Beetle, 2012-2014 Volkswagen Golf, and 2012-2014 Volkswagen Passat, with notes for SULEV and Federal/California emissions configurations. Not for sale or use on vehicles licensed in CA, CO, ME, or NY; check local regulations for additional restrictions.

Confirm the inlet and outlet connection style, O2 sensor port locations, and overall length against the original exhaust component before beginning the repair.

Quality Assurance

AP Exhaust uses controlled manufacturing methods and OE-dimensioned construction to support consistent fitment and repeatable build quality. The stainless steel body and ceramic substrate are selected for emissions-system replacement service on the specified Volkswagen models.
