Exhaust Dia - 02 Aero

[CoonsJA]

Hi all,

Like it says, I am wondering what the diameter is of my Aero's exhaust pipes? I am thinking of getting a universal back box from either magnaflow or borla etc... and am wondering what size inlet i am going to need. I believe i saw somewhere on this a while back that it is 2.25"

What other parts will i need? if the diameter id 2.25 on both the inlet and the stock pipe, will I need a coupler or an overlapping part??

Thanks all!
