the other day i went to the track. the only performance mod i have is an HAI. i also had my 17's on not my 16's. i raced a few cars like a rsx type s and a couple of motor swapped hon duhs. i kept up with all of them unitl about 70mph and then they just left me. my car cant finish the job. it gives up about 3/4 of the way down the track. i am pondering on getting a warpspeed y-pipe and finishing my custom exhaust but im not sure that will help. another possibility is i am thinking of getting some ZEX nitrous. i am not to familiar with the product so i am not sure if you have to add components to your car in order to safely run nitrous. any info will help.

 

I thought that a CAI give you more top end power.

 

hot air intake or hybrid, plus a y pipe will make ur high end and low end like nite and day. i duno how much the exhaust helps that out cuz i got my y pipe and exhaust on at the same time, but i know at least the y pipe will throw u in ur seat a lil bit. by having the y pipe there is no congestion at high end whatsoever

 

Y-Pipe

 

Another vote for the Y-Pipe. The HAI doesn't do much without it.

If your auto, SOL there isn't any topend in the auto. 80-100mph is the dead spot for the auto. Now if your 5spd go Y pipe + ECU if possible. If money is no object order a 2k intake manifold + upper plenum from a nissan dealer.

 

if you want top end, get a pop charger, a y pipe and a 2.5 inch b pipe
