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

JC-Nismo · 02-14-2015, 07:00 PM

What can one do to achieve awesome sound without changing the whole exhaust? Will adding HFC's or Test Pipes to my stock Nismo exhaust increase the groan?

When ya stall the car starting off at a light with the radio turned up rocking to some music, the exhaust is just too dang quite. Just sayin.

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"

Dynos? I found virtually no gains over TP's alone.

However, I don't have a clear comparison of standard, S-tune, and Nismo H with cats or same replacement for cats...

This is the most incorrect/misleading thread I have seen in a long time. S-Tune makes more gains then the OEM Nismo?! There seems to be a lot of confusion about what exhaust is what and a lot of people are using many different names for the same thing.

Stock OEM Z, Y-Pipe design, what the base and sport package come with.
2.4" Y pipe
Cross Section Area 3.52 sqin

S-Tune Nismo, Y-Pipe, not found on a Stock Nismo 370Z
2.4" Primary pipes, joining into a single 2.5" y-pipe, then splitting back to two 2" pipes, through two resonators which stay 2" inside then back up to 2.4" out the back and through the muffler.
~5 whp stock OEM exhaust.
Cross Section Area 3.97 sqin

OEM Nismo, "R-Tune", H-Pipe what comes on a Stock Nismo from the dealer.
1.75" Primary pipes that stay true dual throughout the exhaust. They increase to about 2.25"-2.3" later on down the pipe run near the mufflers. There is a H-configuration crossover near the engine.
~10 whp over stock OEM exhaust
Cross Section Area 4.8 sqin

FI Exhaust
2.5" X-pipe
~20 whp over stock OEM exhaust
Cross Section Area 9.8 sqin

IMO the biggest concern is cost a used good condition Nismo exhaust can be had for 500. A FI exhaust will be hard to find used and a new one will set you back over 1,200. For a difference of about 10 whp.

Got my Nismo for $250 locally, hard to justify that much more money for even 20whp.

Stay tuned!

You can't go wrong with that combination. If you have any questions please let me know.

Resonated HFC's or resonated TP' or LTH's.

Hi Kris, I am looking into purchasing a 370Z Nismo Tech 7AT like yours.

Just wondering, did you ask UpRev to also tune the transmission to improve shift speed? If so, how noticeable is it, and how do you feel it will affect the durability of the transmission over time?

As for the performance tuning, did you do it remotely (without dyno) or with dyno runs?

Thanks in advance...

Ha well he may not answer as this thread is super old but I have a z with 7at and went ecutek route with Seb a specialty z just recently. The shifts feel good and seems like there is less hesitation on what gear to choose at lower throttle / cruise. Oem had kind of a spot on decel when it would do a shift down then back up like a 2-1,1-2 shift if you were just very light on throttle like slow cruise down residential street. It doesn't "bang gears" or anything like that and is still great for street driving, just maybe slightly and very slightly if that a more positive shift.

As for wear, well in theory the clutches should last longer as they are engaging sooner and have less slipping (easing into the shift). Other car lines that have the dual mode normal and sport for their shifting will last longer in sport mode for the same reason. Think of it as slipping the clutch on a manual vs letting it out quicker and engaging sooner. Taken to the extreme either way one will burn out the clutch and the other outs more stress on the gears but find the right balance and they will last a long time. Personally I think the autos with only 1 mode always error on the slip side as customers also persieve anything positive / harsh as wrong.
