Magna flow comes in different sizes. I would go with a 2.25 for a stock or lightly modded N/A 4cylinder

i agree i'm running 2.25 on a slightly modded engine (bolt ons) and it seems good enough. but if your running some cams and what not i think you should go with 2.5

go with 2.25 for stock or lightly mods (I/H/E).
go with 2.5 for major mods.

That setup seems fine.
