i ordered a y pipe and ud pulley
what are the expected gains from each

i'll post results once i put them on

 

what kind of y-pipe? Cattman? St$$lin? or Warpspeed?

 

10-15hp from the y-pipe and maybe 5-8 or so from the UDP.

 

from dynos ive seen and my own experience, id say 10-12 hp and 1-3 for the udp. these are pretty typical for 01 maximas with autos. if you have manual, then add a few 2-3 as a guess. you wont see much gain from an udp on a dyno but you should be able to feel it low end.

 

You'll get a nice gain from the two. UDP will help ya up thru 1st, y-pipe will give ya more top end. You'll enjoy them. Gonna install yourself?
