In an earlier post I stated that a friend of mine with a 03 350Z recently installed a Borla Tru-Duel exhaust on his car. He said that I could use anything that I would like from his stock exaust on my 04 sedan. I know that the mid-pipe will work with an xtension, but is it worth using anything else or can I use anything else. I think that I have seen that the y-pipe is the same. I know I can not run the duel tips, but what about the cats? I plan on doing a 3/8" plentum spacer along with the mid-pipe and my stillen rear section. Are these mods going to show any HP/TQ increases worth speaking of? Any help is appriciated.

 

I don't think it'll be much of a help to use a 350Z Y-pipe, maybe you should look into the Stillen Y-pipe for the coupe (I'm not sure if it'll fit you might want to double check with someone first).

Now about gains, the spacer will help. BTW, do you have an aftermarket intake? cause a combination of breather mods does help with the performance a little bit.

 

you can basically only use the midpipe, i know you cant use the muffler

 

I do have a Z tube and KN filter. I have been thinking about doing a injen or nismo cold air intake instead.

 

Installed the 350Z middy this weekend and sounds pretty good. I also have the Stillen rear section. I am ordering this week the Motordyne 1/2" iso Spacer and Jwt popcharger. Should I see are feel any real differance?

 

nothing crazy........maybe a little difference
