MagnaFlow 94009 Pre-OBDII Universal Catalytic Converter, 3″ Inlet/Outlet (EPA Compliant)

Description

Product Overview

The MagnaFlow 94009 Pre‑OBDII universal catalytic converter is engineered to meet the stringent emissions standards that existed before the OBDII mandate, delivering dependable performance for classic and older model vehicles. Constructed from high‑grade stainless steel, the converter resists corrosion and heat degradation, ensuring a long service life even under demanding driving conditions. Its clamshell design incorporates a continuous seam weld that eliminates potential leak points, while the integrated OEM‑style oxygen sensor ports provide accurate feedback to the engine control unit for optimal fuel combustion.

Measuring 3 inches in both inlet and outlet diameter, the converter offers a compact footprint that can be positioned in a variety of exhaust system configurations. The overall dimensions of 17.75 x 7 x 4.5 inches and a weight of 5.7 pounds make it a manageable upgrade for DIY enthusiasts and professional installers alike. The product carries a 5‑year/50,000‑mile limited warranty, backed by MagnaFlow’s reputation for quality and durability, giving owners confidence in their investment.

Usage

This converter is specifically designed for pre‑1996 vehicles that are not equipped with OBDII diagnostics. It is an ideal replacement for owners of classic cars, vintage trucks, and early‑model performance vehicles that require a reliable emissions solution without the complexity of modern electronic controls. The universal mounting configuration allows the converter to be installed in the exact location required by the vehicle’s exhaust layout, whether that be in the under‑carriage, near the muffler, or as a direct replacement for an existing catalytic unit.

Professional installation is recommended to ensure proper alignment of the O2 sensor ports and to secure the converter with the appropriate gaskets and clamps. Once installed, the converter operates silently, reducing harmful exhaust gases while maintaining exhaust flow, which helps preserve engine performance and fuel efficiency. It is also suitable for use in off‑road applications, such as vintage rally cars and classic show vehicles, where emissions compliance is required for participation in certain events.

FAQ

Is this converter compatible with my 1994 Mustang?

Yes, the 94009 is designed for pre‑OBDII vehicles, and its 3‑inch inlet/outlet dimensions are compatible with many 1994 Mustang exhaust configurations. We recommend confirming the exact fit with a professional installer.

Can I install this converter myself?

While the converter is designed for universal installation, professional installation is recommended to ensure proper alignment of the oxygen sensor ports and secure mounting. If you have experience with exhaust work, you can install it yourself using the appropriate gaskets and clamps.

Why is this converter not suitable for California?

California, Colorado, New York, and Maine have stricter emissions regulations that require OBDII‑compliant catalytic converters. The 94009 meets the older pre‑OBDII standards and therefore does not satisfy the newer state requirements.

What does the warranty cover?

The 5‑year/50,000‑mile limited warranty covers material defects and performance related to emissions. It does not cover damage caused by improper installation, misuse, or external factors such as accidents.

How does the stainless‑steel material affect performance?

Stainless steel provides excellent resistance to rust and can withstand the high temperatures generated by performance engines, ensuring consistent catalytic activity and maintaining exhaust flow without restricting power.
