The MPI Automotive SSMBC225 is a set of 3in high-flow cats, listed to fit the Ford Mustang FM, FN and FO (S550 and S650) 5.0L V8, designed to suit the FX-225 extractor.

What does this part cover?

This is a pair of 3in high-flow catalytic converters for the 5.0L V8 Mustang, spanning the FM, FN and FO designations across the S550 and S650 generations. They are made to suit the FX-225 extractor, sitting between those headers and the cat-back as the emissions section of the system. Because they include catalytic converters, this is the part that keeps the emissions hardware in place rather than deleting it.

What does a high-flow cat change?

A high-flow cat is a catalytic converter with a less restrictive substrate than a stock unit, the idea being to free up flow while still carrying a converter for emissions. At 3in it matches the bore of the FX-225 extractor and the system behind it. The honest framing: it is freer than a heavily restrictive factory cat, but it is still a cat, so it is about flow with the converter retained, not a delete.

Will it suit my Mustang?

It is listed to fit the 5.0L V8 Mustang in FM, FN and FO form across the S550 and S650, paired with the FX-225 extractor. The extractor pairing matters, since the cats are sized and located to suit it. Confirm your exact build with the workshop before ordering.

Is it road legal, and what does fitting involve?

Because the SSMBC225 retains catalytic converters, it keeps emissions hardware in the system, but road compliance still depends on your state requirements; confirm them with the workshop. Oak Flats Muffler Men supplies and fits these cats in the Illawarra, matching them to the FX-225 and checking the 3in joins seal cleanly.
