Walker 93263 Catalytic Converter

Walker EPA Universal Catalytic Converter

Walker EPA 93263 is a universal catalytic converter built for 1997-2000 import and domestic OBDII vehicles that need EPA emissions compliance and dependable exhaust flow. It uses a stainless steel body with a ceramic substrate and a round case design for universal pipe connection applications.

The Walker EPA line focuses on emissions-system replacement parts for federal-emissions vehicles. This converter is part of that range and is intended for vehicles that require an EPA-compliant universal catalytic converter rather than a direct-fit OE-style unit.

Key Features

• Universal fit catalytic converter for exhaust system fabrication and replacement
• EPA emissions-focused design for 1997-2000 OBDII vehicles
• Stainless steel body with ceramic substrate material
• 2.5 in. inlet and 2.5 in. outlet pipe connection
• Round body shape with 13 in. body length and 17.5 in. overall length
• Post-catalyst oxygen sensor location
• Fits federal-emissions Audi A4 and Audi A4 Quattro applications listed below

Detailed Description

Walker 93263 is a universal catalytic converter with a 2.5-inch inlet and outlet, designed for exhaust systems that require fabrication or adaptation during installation. The round stainless steel housing measures 13 inches long, 4.375 inches wide, and 4.5 inches high, with a 17.5-inch overall length. Its ceramic substrate supports exhaust aftertreatment in EPA federal-emissions applications.

Fitment includes 1997-1999 Audi A4 and 1997-2000 Audi A4 Quattro models, with notes for federal and California emissions models as listed in the fitment data. For shoppers searching for a catalytic converter for Audi A4 Quattro 1997-2000 or a Walker 93263 universal catalytic converter for Audi A4 1997-1999, this part matches the documented vehicle coverage and pipe size requirements. This part cross-references Eastern Catalytic 92736 and Four Seasons 2506R for the same application.
