Why doesn't the Z exhaust note :purrrr: like the G37
 

Despite them having the same motor, I've been wondering why the exhaust notes differ quite a bit. While the Z sounds sort of like loud noise, the G37 and FX50's have this deep purrr that I personally think sounds nice

This is what I mean with G's:
[

^^ sounds pretty similar to a 370 with exhaust?

The Z is just meaner by nature.

:iagree:

1. It says in the title "Custom Exhaust" so thats not stock, and even as it is, it sounds just like a 370.

2. Different combinations of resonators/muffler packing material/pipe lengths/bends all contribute to the exhaust note...

Not sure where you're seeing the two sound drastically different, and I dunno if I'd ever say the Z's exhaust is 'noise' maybe in a completely non-resonated setup, but it's not noise then, it's power.

Sorry for the poor choice in wording for the Z exhaust note but I can always tell if it's a G37/FX50 driving by it's very noticeable purrrr exhaust note. Sort of like how you can always tell when a WRX/STI is rolling through. With the Z, I don't hear much of, if at all, that nice purrr from the Infiniti's. Maybe my hearing is going.

I dunno, I've always saw the G's (35's and 37's) always sounded more like a 350 than a 370 with the higher pitches. But I have no problem with my FI exhaust + headers. It gives a nice deep rumble. When I get back home this weekend, I'll take the go pro out and do a start up vid for you...

sounds like a proper true dual, no x or h.

also i'd hate it if that noise came from my car.

u can always doda washer mod...

The 370z is super quiet. The 350z had a nice rumble maybe like the g37. I don't know why Nissan would make the 370z sound like a Lexus.

Straight pipes should please you ;)

I like how the kids across the street completely stop what they're doing to stare at the jackass who's revving his engine in his driveway for no reason.

Op I know exactly what you mean. That was the first question I asked my salesmen. He said "no they def sound the same" to which I replied "no they def don't sound the same." Needless to say, I never got a straight answer.

Having just come from an '08 G37S to an '11 Z, I honestly can't hear any discernable difference. To me they both have a very sophisticated rumble to them.

damn dude is fat ... lol im j/k

If you want to hear the exhaust, put something near the back side of your car. For whatever reason, when my bicycle is on the back of the car. The exhaust would just change note and turn super noisy, it would start to drone. At first I thought my exhaust was loose, turns out either the bike carrier or the bicycle itself is changing the exhaust and its frequency. It's the weirdest thing given the 5-6" gap at the exhaust tip

Well, the stock exhausts of the G37 and 370zs are identical. But maybe the G37 exhaust was designed to be slightly louder to offset the additional sound deadening whereas the Z's exhaust was designed to be slightly quieter due to the Z's lack of sound deadening.

You can't compare aftermarket exhausts though, it is apples and oranges due to the variations between different aftermarket exhausts.

IDK...but to me both the "stock" exhuasts for the 370 and G37 sound identical...Now the 350 and G35 stock exhuast has a bit of a purr and rumble...as a matter of fact the 350 and G35 sound a lot better stock for stock compared to the 370 and G37. Only way to fix the issue with the 370 anr G37 is to upgade to an aftermarket exhuast system

I have to agree with the OP

In my Condo Building there are 3 G37's. When they drive away, there is a nice purrr to the exhaust, like the FX45 but the Z sounds really really quiet.

That always upset me, I figured the Z should sound much sportier of the 2

However, I have the FI exhaust now, so all is well and I don't feel inadequate with my exhaust note :)

The stock 370Z exhaust is quieter than my G35 stock exhaust was but they both sound great. Now I have an aftermarket exhaust on the 370 and trust me people hear it and it sounds great IMO. Honestly, I didn't even look at replacing my G35 with a G37 so I don't know what the stock G37 sounds like.

I've always noticed this when I had my 350, I could always tell a G35 over a 350. And its the same with the G37 and 370. I think its because the G has longer pipping since it has a longer body style.

Anyone who says they sound identical is buggin' out or you just don't know. Having owned both and the G35 as well. The G is much deeper, while the Z is more whiny. The G resonance is reminiscent of a v8 while the Z sounds distinctly like a v6. I found the gencoupe and G to sound closer together than the Z and G.
I can hear a sub-tone in both that helps me identify the 35 and 37's and Z's as VQ's, but there definately is a difference in depth. Why I don't know? Maybe its the length in exhaust piping. The G is a foot longer.

A stock G37 and the FX both have more pronounced exhaust note than a stock Z's but as soon as you go aftermarket there is no comparison...

I have never seen someone take a G exhaust apart and compare it to a Z's exhaust but I'm sure it has something with the length and exhaust internals as stated by others.

I actually had the G37S before, now the 370Z. The G was def. louder than the Z with stock exhausts lol

maybe nissan didn't try to tune the sound of the z as much as the g because 90% of z owners are going to ditch the stock exhaust anyway...

There is a discernible difference between the two. Unlike the 370z, G, FX, and EX sound the same.

Do you work for a politician? The figure is pathetic...

82.5% of all statistics are made up anyway :stirthepot:

This is because,all cars in the world that produced after 2008 have to confine to a new sound limitsin the E.U.,included Ferrari,that why the lastest Ferrari 458,is also very quiet in standard mode.

Why is that weird? 5-6 inches is nothing.

my dad has a G37 and I notice a difference. I have no idea what causes it, but his actually muffler is longer than mine... IDK if that has any effect just throwing that out there

Opinions are like a$$holes.... everyone has one. This is (IMHO) a purely subjective argument, thus the many opinions. I won't spoil the debate by posting mine, thanks.

Anyone know if you can swap the G37 muffler for the 370Z muffler?

I agree with the OP... sounds like the G37 exhaust (and 35) is tuned for sound. You have to expect some things like that when you're paying a premium over the 370 (obviously the 370 is much more badass though lol).

The 35/37 and honestly even the 350z seem to me like they have more of a "pulse" sound to them... I was also surprised about how quiet the stock exhaust is but it didn't last long anyhow.

to those that agree with me, thanks for reassuring me that i'm not going crazy. if you listen to any number of aftermarket exhausts (ex: youtube stillen for the g37 and 370), you can tell there is a "pulse" sound, as mattp put it, to the g37 that is simply not there on the z's.
this is most apparently to me when i'm at a local z meet, where there is a range of different exhaust setups, and listening to other z's showing up and leaving. none of them like a g or fx

The Z & G37 do sound the same or very close IMO. I think a lot has to do with how your hearing it. I drove a G37 and the interior has a lot more insulation. I think it drowns out some of the high notes. From outside the car, they sound very close, stock vs stock.

You are right and I have noticed that as well. I think the exhaust on the 370z sounds like the one on the IPL G37.

Maybe more G drivers have their AC on compared to Z drivers? A lot more 'purring' when it's on...

Yup... you have had to own both to really know. When u live in a car day after day then trade up with a new one immediately. You here things that you can't hear on a video. The G definately had more depth. The Z still sounds good though. Just not as good as a G.

:iagree:

The Z doesn't need an exhaust tuned for sound, it needs to be tuned for power. Its one thing to look and sound fast and another to be fast.
