If I have a 2002 automatic max, will a Y-pipe add any kind of hp to my car with an injen intake and an arospeed exhaust? I read on another post that the Y-pipe does not do anything for 2002-2003's. Another quick question, will 19X 9 fit our maxima or is that too wide? Thanx

 

I added the Y and B pipes and it added 5hp and 6tq. No one has dynoed just the Y pipe as of yet. I felt a butt dyno difference, but that could be in my head. It definately sounds better than stock in my opinion.
