y pipe gains?

[jaym5k]

I have the Nismo catback, intake and ordered a kinetix plenum. What do you guys think my next mod should be? I was thinking about high flow cats. Sorry for the wrong title i realized that the nismo catback comes with the y pipe.

High flow cats are good. I have test pipes on mine and it makes the exhaust a little raspy after 3k. You will only get a minimal gain but it makes the exhaust sound a lot better.

well since i was kinda broke and noticed some brown ick on my old plenum (before i got the kinetix v+) i just blew the rest of my money on a greddy oil catch can, godforbid i was $800 away from the next thing i needed.
