Hey guys, whats up? ive got a couple questions I was hoping someone could help me with..

first off, ive got the typicall NA breather mods.. MREV, 5/16 space, resonated TPs, short ram. Now i want to (add a Y pipe) and tune everything out.

From what ive been reading, i think ive narrowed my choices down to the two produtcs mentioned. can anyone tell me some pros & cons between the two? from what i can see, either one will do the job, but i want to hear what you guys have to say.
Also, what advantage do i have with the Emanage support tool?

thanks, Gunner
