Is this worth to get it ??? will the Y-pipe make a change on the sound or just the HP increase ???

 

It will change the sound slightly, just a touch more of an aggressive exhaust note. Your wife/GF will probably not even notice.

 

And Horsepower?

 

talking to custom interprise, the dude told me 15-20 whp, yes whp not hp. Well waiting for it to come in and I'll let u know. On my other maxes, the y-pipe was the best mod for hp for price. the hp was definetly noticable but barely increased in noise with a stock exhaust.

 

 

look at the 4th gens they get about that much power

 

Is custom interprise the only one who's making the Y-Pipe for 04 Maxima ??? anybody know ???
