Ok I have got some extra cash again, and looking to mod..again.
I am really in between on a CAI, Y-Pipe or an UDP I just can't decide what should be first. Which do you guys suggest first?

Also I will hopefully be getting my AGX and Eibachs installed this week if my installer has the time

 

CAI is the traditional first mod, but a y-pipe will give best performance for the dollor
