Catco 9248 Catalytic Converter - Right

Catco 9248 Catalytic Converter

The Catco 9248 is a Federal / EPA direct-fit catalytic converter built to OE dimensions for straightforward replacement. It uses a stainless steel body, a ceramic substrate, and a 2-bolt loose flange inlet and outlet with spherical flare connections for a precise exhaust seal.

Fits 2003-2004 Ford Expedition, right. This application is listed for Federal and California emissions, with state-use restrictions noted in the fitment data.

Key Features

• Federal / EPA direct-fit design for a direct replacement path.
• Stainless steel body for corrosion resistance in exhaust service.
• Ceramic substrate for efficient catalyst function.
• 2-bolt loose flange inlet and outlet with spherical flare connections.
• Two O2 sensor ports for the specified exhaust configuration.
• Built to exact OE dimensions for proper alignment and fit.

Detailed Description

Catco 9248 is engineered as a direct-fit catalytic converter for the Ford Expedition, right side application shown in the fitment data. The 45.5-inch overall length, 2.50-inch inlet ID, and matching flange-style outlet support a factory-style exhaust replacement where dimensional accuracy matters. The stainless steel housing and ceramic substrate are paired with Catco's ARISTO substrate chemistry and automated manufacturing process to deliver consistent converter construction and efficiency.

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

What It Is Used For

• Replacing a worn or inefficient catalytic converter.
• Restoring exhaust flow through a direct-fit converter assembly.
• Addressing emissions-related converter failure codes tied to catalyst performance.
• Correcting exhaust leaks at flange-style connection points.
• Restoring proper O2 sensor placement in the exhaust system.

Installation Notes and Tips

Verify the vehicle's emissions certification and state restrictions before installation. Confirm the right-side application, inlet and outlet flange style, overall length, and O2 sensor port count against the existing exhaust layout before beginning service.

Quality Assurance

Catco uses advanced manufacturing methods, including automated workstations, spinner welding equipment, and high-speed production lines, to build converters to exact OE dimensions and fitment. The brand's ARISTO substrate chemistry is used to support efficient catalyst loading and consistent converter performance.
