These days, the DIY or do-it-yourself crowd is all about creating custom work and one-off exhausts are no exception. Whether you're working on a classic car, race car or just your daily driver, a MagnaFlow universal converter should be the standard building block for your custom exhaust. Since these items are universal, some modifications may be involved such as cutting or welding.

    • Q:

      My converter has 2 oxygen sensors but this one has only a hole for one sensor can you eliminate one sensor? Will it work? Can you provide instructions? I have a 2002 Subaru Legacy with 2.5 four cylinder?

        Happy to help, Rick! Your 2002 Subaru Legacy with 2.5L Engine has two converter bodies. You'll need the Walker EPA Ultra Direct Fit Converter - Part No. 54562, which has pre and post catalyst oxygen sensor ports.
