FI vs. stock NISMO exhaust, In for a penny...

BlackZeda · 02-11-2015, 09:58 AM

I am planning on getting a FI exhaust as I have a suspicion that there will be a performance boost over the stock NISMO as I can't find any comparisons here or anywhere else.

My question is if you were in this situation, would you go ahead and get the FI HFCs as well since the car will be in the shop anyway? I can afford it, and I figure in for a penny, in for a pound.

Also, I am planning on installing a Stillen supercharger at the end of the summer, so I am laying the groundwork for that.

Thanks for your feedback!

I can't see a reason why you wouldn't go ahead and install them at the same time. Should be a labor cost savings, although I'm not sure it will be much.

~ 9 HP with the Nismo.
~20 With FI.

Stock cats.

I gained a little over 30HP with the mods in my sig. Not to mention how awesome the F.I. + HFC combo sounds.

any aftermarket exhaust will show performance gains over the stock nismo cbe. the nismo cbe doesn't really gain you much power vs the regular stock Z cbe. it just sounds a little different really. the extra nismo HP comes fro mthe tune they put on it.

you can not go wrong with any product from fast intentions. if you want even bigger gains then dropping the cats will provide it. HFCs wont show as big of gains but will help along with give you a great sound as well.

my first set-up was FI non-res test pipes and FI non-res CBE. a bit much for most but removing the cats will help gain more power. if you're going with a supercharger the FI will also help you add HP there as well.

I've noticed gains on the FI exhaust however the Nismo does make really good power. Here's a dyno run or a 2014 with the Nismo R tune exhaust:

This one has headers and FI exhaust:

Both vehicles have Z1 headers installed

I assume Nismo R tune is not the same as Nismo stock.

It's off the stock Nismo 370Z. The S tune is the optional one that lacks performance.

I did not know it was called R Tune. I have heard of R Tune CAI, but not of R Tune exhaust. I learn something new everyday.

That's what I call it

The S tune (R tune?) is NOT as good as the Nismo OEM H-pipe in terms of power.

Most gains will come from swapping out the cats with either HFC's or TP's.

I don't know what the FI exhaust is going for, but my guess is that if it's, say, a few hundred more than someone's used OEM Nismo H-pipe cat back, the gains/sound will only justify the price differential if you have money to burn.

If I were you, I'd just get the HFC's.

BlackZeda · 02-11-2015, 02:06 PM

From all the responses I will go ahead and get the FI cat back exhaust and the Resonated HFCs replacing the stock NISMO components.

As a little background as to why I am doing this; I test drove both BMW M4s and Corvettes this last summer and decided to keep and boost my Z. The only thing that I really loved about either were the great exhaust tones.

Also, I am doing an Uprev tune, so I will see if they can do a dyno before and after the exhaust install.

Stay tuned!

Nothing but FI

Hmmmmmm... I disagree... The S-Tune WILL for SURE make more power than the OEM Nismo exhaust
I have an S-tune exhaust. It's much better than the OEM Nismo, much bigger piping. 2.25", but most other aftermarkets are 2.5"
