It's all mostly a matter of opinion. It really boils down to what you want to pay (fabbed duals) or what you can do in the driveway (3" catback).

well no i have duals on my car already and i have a full 3"catback sittin around. i dont no if i should keep the duals or not because i am thinking the size of the pipes is stock size and might not be to good for power but since it is duals might be better, and what i want is better performance but i dont no what one is better.

chances are your true duals are press bends, and not mandrel bends. the 3" catback most likely has mandrel bends. as long as you can get a 3" mandrel-bent y-pipe, the 3" catback would flow better.

Duals are not really necessary. Go with the 3" single unless you plan on making alot of power or just like duals better.
