I was looking into purchasing a y pipe, cat, b- pipe and a muffler for the max. I was looking for the best performance that was out there for the max. i was just wondering what combo produced the most horsepower?

Could anybody tell me what you have on your maxima? And what numbers they produce? The higher the better!!

 

No setup will really yield you more than another, maybe like 1-2hp IF THAT..

I personally have...

Budget Y
Stock cat (least HP gain, not gonna change it)
Stock B (not for long, either budget or custom)
DynoMax dual exhuast

I'm running the following:
APEXi WS catback
RT Cat
WSP y-pipe.

I really love the sound of this setup and provides pretty good performance. Like 99Maxima says, no setup will provide significant HP advantages over others. Just go with your own tastes and budget.
