Our take on the MagnaFlow Catalytic Converter

The MagnaFlow Direct Fit Catalytic Converter is a bolt-on replacement for a factory converter, built to fit the stock exhaust without cutting or welding. This version is a direct-fit unit without an air tube and measures 37 inches overall. It is aimed at drivers who need to pass a smog check and want a stock-style fit rather than a universal weld-in converter. Against universal converters, the direct-fit design saves installation work, but it is vehicle-specific and carries a California EO exemption number rather than being legal in every state.

Questions and answers

Will this converter pass a smog check?
It is built as a stock replacement converter and carries a California EO exemption number. Check that the EO number and part number match your vehicle's engine and emissions setup before buying.
Does it bolt on without welding?
Yes. The direct-fit design has flanged ends that bolt to the stock exhaust, so little or no fabrication is usually needed. Rusted original hardware may still need replacing.
What is the difference between OBD II and Pre-OBD II versions?
Pre-OBD II versions suit early vehicles, generally 1995 or older, with 2-way or 3-way converters. OBD II versions are for later vehicles with on-board diagnostics and monitor the converter electronically.
Is it legal in California?
The listing shows a California EO exemption number, which is what the state requires for aftermarket converters. Confirm the EO number covers your specific vehicle before installing.
Does it come with gaskets and hardware?
MagnaFlow direct-fit converters are generally sold as the converter itself. Reuse or buy new gaskets and bolts for the flanges to avoid leaks.
Where is the MagnaFlow Catalytic Converter cheapest?
At eBay, for $419.99, 33% under what the other stores charge, as of our latest check.
Where can I buy the MagnaFlow Catalytic Converter?
