so i have my Evo I exhaust installed, and wonder what brand makes good y pipe for 03 sedan that make the exhaust louder....from the research i know there will be no HP gain.. however, couldn't find a post about the sounding for an aftermarket y-pipe....help me out...

 

i would directly link it but its blocked. go to google and type 350z wiki y pipe. hit the second link and there are all the y pipes available. choose one that matches the inlet of your evo 1 exhaust. smaller pipe going into larger is fine but stay away from a y pipe with an outlet larger than the inlet of the evo 1.

 

you have PM...

The result will be an annoying nasty rasp.

 

after researching...i think my exhaust inlet is 60mm.....is it possible???
and i can find any y-pipe that has a smaller or same exit diameter...
i think even the stock y is bigger than that...
help me out

 

Thats roughly 2.5 inches. That's going to be tough. I remember only seeing Y's with 3" openings before.

 

yea...thtz what i remembered too.....any luck???
