Just wondering...
If I were to get an 11" Magi Si/so with 3" (or 2.5...which is better), would I need a custom tune? Would it cause any problems running lvl 2 on my Evo?

So a CAI is the only thing that'll really need a custom tune to utilize?

Also, does anyone know the part number for the 4x9x11 maggie I need? I see one is offset inlet outlet and ones inline. Don't I need the offset?

You need custom tunes if you remove cats or add headers. A cat back exhaust does not require custom tunes.
