Nismo vs Stock Axle Back only.
 

Is there a significant difference between these two?

Visually: Yes

Performance: ?

Performance, no. The WHOLE exhaust is only worth 4WHP

^^^ For the S-tune, I agree.

For the Take off w H-pipe, I beg to differ...

Go with an eBay axle back if all you want is noise. Axle backs don't add performance(it might but there is no definite proof) so if you are gonna get one, might as well have it cost as little as it can. Axle backs can be found for under $200(search G37 axle back not 370z, same part with a lower price) on eBay.

I have seen one on a 370z today and it doesn't look or sound bad.

see if you can find a stock g37 muffler. its a bolt on and will procured a better exhaust note as it got grandfathered in before Japan changed the noise requirements. I sold mine to a Z owner for $50 a couple years back

What's the difference between the s tune and the one that comes on the Nismo?

piping design, the nismo s tune exhaust is a bigger version of the regular 370z exhaust, the nismo 370z exhaust is a true dual exhaust with an hpipe instead of a y pipe

s-tune is a quality piece made by Fujitsubo and offered as a Nissan accessory. the nismo is an oem piece that comes with the Nismo trim.

if you want an exhaust, it's advisable to go aftermarket like Fast Intentions. picking up a nismo exhaust for 300ish used is also a good option if you're on a budget. much better than getting aam short tails..

Well I plan on getting a FI with 18 inch resonators, but was offered a used original Nismo exhaust for $200 and figured it couldn't hurt in the mean time while I get the FI.Plus the Nismo one comes off 2014 so it doesn't have much use and once I get the FI I can sell this one. But what I got from this thread is that the OEM Nismo is better than the S tune.

That would be a steal since the wholesale cost at the dealer is $1,600. The NISMO exhaust has a nice low rumble that won't drive you out of the car, but probably won't provide the gains as some of the other aftermarket systems.

Good Luck.

yeah, that's a good plan.

The S-tune has a slightly larger diameter Y-pipe, which I can tell you from experience is prone to cracking, and made about 1-3 whp throughout the rev range (search through my proven power dyno thread for details and lots of commentary).

The "take off" has a H-pipe, which appears to greatly outperform the S-tune version.

For further commentary, comparison dynos, detailed reports, see the aforementioned thread -- easy to search for.

In short: I would NOT spend the money on the S-tune, even used; buy a Nismo OEM take off for better results.

I have no special opinion on the sound difference -- they both sound fine. Louder than stock, but not enough to wake the neighbors.

Main reason i asked is because of the AAM Mid-Pipes i currently have.
Seems like the majority got it confused with the whole nismo exhaust. (i know it sucks)

Im interested on the Axle part only, is it less restrictive than the base muffler?
My interest sparked from the Nismo Dyno sheet.

Reason for my interest, plan on adding a HFC later. Figured it will sound and preform better than having the Short Tails with HFC.

Or could the Nismo numbers be because of the nismo tune?

Run 1 is stock, Run 2 is adding AAM short-tails.

I mean that's proof to me. :tiphat:

Well I got the OEM Nismo H pipe exhaust on this weekend and I must say there is definitely a difference from the stock exhaust. Not sure how much I gained in HP but the engine does rev faster and it has a deeper tone but not louder. Very happy with it but only intend on using it until I get my FI 18". I'm wondering if it would be cheaper just getting a less restrictive muffler and still give me the gains an aftermarket would? But hey for $200 it was worth it. :ughdance:

also the nismo exhaust that comes on the car is made by Autech. theres a little nameplate welded to it.

Sorry to bump the thread. But i still find posts provided a bit unclear as it led to midpipes or about the full nismo exhaust.

Short Tails got a bit annoying for the wife. So i plan on swapping those out by
adding back my base muffler. I posted this thread to see if anyone knew if the Nismo Muffler (axle part only) is less restrictive than the base muffler. I want to maximize my chances of keeping better gains between those two.

Thanks!

There's a DIY where a guy cut open a Nismo muffler to make it less restrictive (and louder). From the looks of the internals, it looks like a pretty standard muffler design so my GUESS it that the Nismo muffler is not any less restrictive than the Base muffler.

I had the OEM Nismo cat back on my Base for a couple months. At WOT it honestly didn't sound much louder than stock. I noticed more of a difference while cruising / lower RPMs. It's a tad louder and has a slightly deeper tone to it. I read one thread suggesting it was the dual pipe design of the Nismo that attributed to the sound difference, not so much the muffler. Hope this helps.

the nismo muffler is a better flowing muffler than the base Z, you can google around for the flow pattern, it just isnt louder than base

I stand corrected. Thanks for the clarification.

Perfect!! Thanks guys!

I'm on the fence, I was offered a Nismo exhaust installed for $500 and I believe it's the S-tune because he described it as a "full stainless" set up... I was wanting to do the motordyne e370 before he offered but this will save me some dough for other mods I figured why not for the time being... Am I making a mistake ??

Honestly... yes. If it's not the H-pipe "take off" Nismo, I would pass.

The Y pipe on the S-tune exhaust cracked and needed to be repaired twice and it made very, very little power over the OEM Z exhaust.

It sounded pretty nice, but I went with the Nismo H-pipe take off on the next go-round, and couldn't be happier with the sound or gains.
