Magna Flow 50 State Cat Carb E.O.

[dktool]

that's the second vehicle i heard that about from magnaflow's site.

The "they" in my statement pertains to CARB, not Mangaflow.
Magnaflow's p/n is correct to the sizing spec mandated by the xxxxxx-103 E.O. number.

That 103 E.O. number is called out for hundreds or even thousands of car manufacturer models all through the alphabet. Basically everything with 2" piping.
