I'm also interested in this question. I just got a G35 Sedan and would like to add some power to it without all the noise. Last thing I want is a nice Infiniti running down the road sounding like a lawn mower.

 

def go w/ the fuji, the nismo is nice but its like $2k for the one for the G. and if you get the one for the 350z w/ the 6in extension, then your tips will be 2in short

 

Where can I buy the fuji?

 

I have the Tanabe and the sound aint too bad....

 

You might also look into the HKS Hi-Power for the G. No drone on the hwy. and when taking easy around town it's quiet but noticeably deeper than stock. Mash the throttle getting the revs over 3k and it comes to life with an exotic sound that's really nice.

Plus the quality and look is really befitting the Z and G.

 

Is that on a Z?

I hear clips of the Weldina Nismo for the G and i like the way it sounds.

 

from what i have heard, i think fuji is the most quiet. imo the nismo is louder than fuji.

 

fuji is the quietest for sure. yes i have it, along with CAI, y-pipe & cats, and still super quiet (when it is supposed to.) pretty damn loud WOT. i can easily set off many car alarms in mall parking lots when i rev lil hard. (yes, i do it intentionally.) i heard HKS hi power is quiet too. i raced another g35c with HKS with my windows open, neck to neck race, and it had very similar sound. IMO, HKS is little louder than fuji, it looks much cooler, but weigh a lil bit more than fuji.

the real important thing is that fuji doesnt sound ricy. neither does HKS.

if you are really concerned about making your car too loud, you should consider HKS or fuji.

 

i thought fuji makes the nismo, meaning they are basically same, just with different looking tips. nismo, for its names sake, is just more expensive, i believe.

 

does the fuji give any power gains or is it mostly for sound?

 

yes, it does. i would never go back to stock now that i got a taste of the fuji.

 

What will this setup do for me sound and power wise? How much for the combo? I love the initial bark when you start the car say at a gas station! I hate to mess with the sound cuz I love it but just wish it was a bit louder.

 

I know the nismo exhuast on the z does not fit the g perfectly. But does any one know if I were to get just the nismo muffler and have a muffler shop custom make me the piping could it fit perfect?

 

Even after adding an ext. to the nismo, the exhaust tips will still be sitting about 2" back compare to the stock G35 exhaust...the exhaust tip are shorter on the z, do a search on G35driver.com for some pics.
The weldina is the only NISMO exhaust made to fit the G35 w/o any modifaction.

 

Just add some resonated test pipes and be done with it. It will deepen the exhaust note with no rasp or drone at all. At least it did on my G until I added the y pipe. That's when the rasp and drone came.

 

Fujitisubo makes the exhaust for Nismo but it not the same exact thing, well the mid pipe and y pipe is but the muffler is a little different. The fujitsubo is a little quieter than the Nismo but it still yet very tasteful and sounds very nice, similar to stock.

 

I went back to the oem muffler and I have Alphawerks Headers and Kinetix HF Cats. The sound is slightly louder than the stock setup, but keeps that distinctive oem sound (I love it). There is no freeway droning. I just ordered a Tanabe Y Pipe to finish off my exhaust system. I regained my low end torque - very happy with system.

 

thats the same setup I was shooting for Keith N. Did u ever get any dynos bc I'm curious how much hp difference this will be with or without the exhaust. Also, are u AT or MT?

 

I've heard a Blitz exhaust on G35 and it seemed really quiet.

 

Sorry, no dynos yet. I can listen to the stereo at lower volumes and carry on conversations on my cell while driving. I've got a 2004.5 5AT.
