NISMO exhaust (not S-tune) on a base 370Z (sport)...
 

Yes- it will fit. The tips look like saucers after the standard exhaust. Nice deep tone.

Thanks Elliott.

looks good man

Did you notice a difference performance wise over stock? Just curious.
Thanks,

Looks good, I had heard when the Nismo first came out that the exhaust would not transfer to the 370z. Something like the exhaust is too long or maybe it was too short. Did you have to get a tune to get the same +17 hp claimed on the Nismo?

I had read a thread earlier that indicated the actual NISMO exhaust would not fit. But after some serious measuring, it looked to me like it should fit not problem. I took it to my buds at the dealer. $95 and an hour later they were done.

Performance-wise, my butt dyno is not a very good judge. I have not had tune. I'm just letting the ECU think about it awhile. The sound change is immediately apparent - very nice.

It's actually exhaust + different tune that produces the 17 hp difference. The exhaust alone will probably get less than 17 hp.

It sure does fit, actually better than my S-Tune. Curious what dyno numbers the car would achieve. Also a sound clip would be cool.

Pretty much what I was asking, you just stated it more concise. :tup:

With the H pipe design and a remapped ECU = 17hp gain. :tiphat:

I wonder if you can find a used Nismo ECU and just replace the base model ECU. Anyone see problems with this?

Yea the problem is finding a used Nismo Ecu. If you do find one put me in for a group buy..

Nismo exhaust is only good for ~7hp over stock Z. The majority of the power comes from the tune. There isn't much difference between the stock exhaust and the Nismo. One week after I got my Nismo and swapped it out for my previous Z's FI 18' resonator with carbon fiber mufflers. There was a good noticeable gain on the butt dyno, not to mention a difference in sound and much lighter in weight. For me the Nismo was not much better than stock in the sound department. For a stock Z the Nismo exhaust is a good upgrade for those looking to not spend that much money but personally i think it's worth the extra money to go with aftermarket. My Nismo exhaust is just sitting in my garage for now.

So I'm totally reviving a thread from the dead, but the Nismo exhaust does sound noticeably nicer than the stock base exhaust. The best part is the sound doesn't drone or impede music/conversation in the way that some exhausts are prone to. The tone is much deeper and the car seems to rev a little freer in the upper rpm range. The tips are much nicer than stock as well, so you get an aesthetic benefit also.

The Nismo exhaust is good for people who want a little nicer sound and a little nicer output for a price lower than a new aftermarket system. It fits well also, you simply use two of the rear section brackets instead of three.

So, I am reviving this thread again, as I have a 2013 roadster and a chance to get a nismo exhaust for 500 bucks...is it worth the investment? Will it really sound that different? My exhaust looks almost exactly like the Nismo...What is the difference? I don't want any warranty issues, as my car is 3 months new and 3400 miles on it...I haven't done mods on anything since my '69 vette back in the 80's...And ...if I get this exhaust and the Nismo CAI, then I will need a tune right?? Will Nissan honor my warranty? Do they do tunes?? Yep, lots of questions..

Probable gains below (note that this is with K&N panel filters and smooth tubes for both sets of runs)

You will not need a tune, although getting one may net a bit more power. The above dynos are, I believe, with the OEM tune and cats.

See more dynos and lots and lots of exhaustive analysis and discussion on the H-pipe Nismo (and other mods) here http://www.the370z.com/south-east-re...-thread-6.html

Thanks Jordo!..looks like It is a modest but notable boost...and the sound is nice from the Nismo...I have even heard the sound is nice with the Nismo catback and stock muffler...500 bucks for 10 horsie..not so sure...I have a couple of weeks before my buddy passes thru the town they are in...decisions .....

Listen to them ong his car before u buy ? But for $500 , your 1/2 way to aftermarket.

I drive a Nismo and feel that my exhaust tone is embarrassing compared to those guys who run the respected aftermarket exhausts i.e. FI, Stillen, Berk, etc... If you're going to spend the time and effort, go with something like FI. Compare YouTube sounds and you'll see what I'm taking about. If warranty is an issue, just wait it out until you're closer to the end of your warranty.

I wouldn't expect significantly greater gains from any other exhaust that will cost double that... also, you can also probably pick up a Nismo take-off for under $500...

For substantially larger gains, the OEM cats have to be replaced with either high flow cats, test pipes, or long tube headers.

Whatever you decide on, you should definitely get a before and after dyno -- good luck :tiphat:

Yes, I have found a take off from a Nismo for 500, and some Berk HFC's for 350, new in box...so If I get these and don't want to change my chip tune, will it still run better, and run right thru the rpm range? I have Full warranty minus 3 months since car was purchased new in April...My shop said they wouldn't even mention the cat change if I blew my engine or something serious....The problem is I don't want to mess up a perfectly great running car...Just want better sound without voiding the warranty...The mastertech at my dealer told me the HFC's would wake up my stock exhaust and that the only significant difference is the H pipe on the Nismo....I hate to drop 500 and be disappointed in the Nismo exhaust...Has anyone put HFC's on as the only or first mod??

I hate to sabotage anybody else's sale, but I think I let my stock Nismo exhaust go for $225. Maybe I got ripped off... but as everybody is saying, much more and you could go aftermarket.

The carbon fiber FI exhaust sounds AWESOME. I've had people that don't even own Zs approach me and ask all kinds of questions and multiple females have described the sound as "sexy", which is a win as far as I'm concerned. :)

The nice thing about the Nismo CBE is that there's not much (if any) drone in the cabin. Even with the 12" resonator on my FI CBE setup, it's hard to talk on the phone and I can't really listen to audiobooks at a reasonable sound level, even on an aftermarket stereo setup. Music is fine.

Hope this helps.

I bought my Nismo catback for $250 locally. I love the sound but probably wouldn't pay any more than that.

Yeah, something in the $250 - $350 range picked up is about right...

I wouldn't be overly concerned with HFC's voiding a warranty for the drivetrain -- it's more that if for some strange reason they failed, Nissan isn't going to replace your cats. Otherwise, its a pretty safe and reliable mod with solid gains (and environmentally responsible to boot).

As to a tune, I'd say not critical, but recommended for a cat back and highly recommended for any swapping out of the OEM cats.

I'll make one other point that frequently gets lost in the shuffle: Changing the exhaust set up on this motor and not getting any hiss or rasp is tricky...

HFC's and TP's need resonators.

Larger diameter Y pipes (and allegedly, aftermarket H and X pipes) tend to make "whooshing" sounds.

And so on...

Before you commit to any exhaust (other than the S-tune, which is, frankly, of poor quality and makes virtually NO extra power, or the Nismo H-piped take off, which does make decent gains) make sure you do a good bit of research to establish what if any weird rattles, hisses, or rasps will crop up...

Good luck!

Do the carbon fiber mufflers on the FI exhaust sound different than the regular mufflers, or is the carbon fiber purely an aesthetic difference?

I would venture to guess the latter -- aren't they just an outer wrap?

Thanks, and I'm likely going to wait for better deal. Actually with top down my car sounds great when I romp it or when downshifting. I don't want too much attention, as I am fairly aggressive on a regular basis. My car leaves me smiling every day and I've had a lot of fast cars over the years. This car does it all really well and I am pleased with its rigidity. It is as stiff as my crossfire was, which means rock solid. And 110 more horsies. HFC's will be my go to first mod as it really sounds great and opens up the flow. Again, you guys rock.

Nah, it's not a wrap. They are significantly lighter and sound different as well.
