hey i'm just way too lazy to look around much on this subject (at least i'm honest) but i am trying to help out my father in law to see if it is at all possible to run a true dual set up like i have on my z on to his g35 sedan and what all is needed

 

Im not sure. Have you looked under the car to see if there is room.

And since Im a girl and dont know that much about cars...

wouldnt a true dual exhaust include the manifolds/headers, cats and exhaust?

If that is the case I do not think so unless you make some other mods.

 

the evap needs to be relocated on the passengers side of the car.

 

if you are running stock exhaust then u dont have a true dual.. just an fyi

 

 

There's about 3 dudes that's done it to their first gen sedans on here.. they all had to do mild custom work... here's a setup that Jeff92se has done..

Ttrank did it, search for his threads or pm him.

 

Stillen makes a true dual system for the sedan, but what I suspect you mean is it has dual outlets, one on each side of the car, like a coupe or Z. s/n saskicker32 has done a nice dual setup. Search!

 

I think like 8 people on here have done this already. Just search all the info is there.

 

Why would you want dual exhaust? You'll lose torque that way...

 

^^ That would totally depend on the system. Take it for what it's worth, but the Stillen Gen2 claims torque gains of 20+ lbs-ft.

 

I'm allll about torque , where did you see that claim?

haha, hate to break it to you man, but your Z doesn't have a true dual!

Relocate your fuel evap (big box on passengers rear axle back) then chop out ALL of your exhaust up the the cats and rebuild it without a Y pipe.

 

Here's mine, I was the first to try a true dual pipe, real dual exhaust setup:

Custom dual 3" turbo back with wastegate dumps routed back into exhaust

There are other options like your Z has with dual tips but a single pipe.
