Hey guys, im currently running intake and exhaust, and thought it would be fun to go ahead and throw on a little NX and Slicks, but aside from all that i am looking for the best NA gain for the buck, i am HIGHLY considering a Budget Y-Pipe, but their site is down and i can't find out how to order one, can anybody tell me the predicted gains for a Y-pipe, a list of recommended manufacturers as well, and also any other mods that have the best bang for the buck thanks alot

y-pipe on the 2002 gives very little or no gain at all

some people dynoed and lost power

now, if you had an 2001 or older you would see a lot of gain with a y pipe

 

maybe hotshot headers?

 

I would recommend headers to anyone with an 02-03 thats wanting to get noticable N/A power...

 

If you really want a Y-pipe, I recommend Cattman. I have it plus their catback exhaust as well. I am not disappointed with the gains.

 

This question was asked a couple of weeks ago and someone posted this dyno information from Cattman. According to this info there are good gains for the 5.5 gen, just not as much as with 4th and 5th gen Maxima's.

Based on Cattman dyno for Y-pipe on auto 2003 Maxima:
