NISMO Exhaust

355890 · 03-15-2009, 10:22 PM

Trying to identify if there any increases with the NISMO exhaust.

I plan on getting the Berks HFC's to go with the NISMO exhaust.

Anyone with this set-up?

A shop in Georgia dynoed the Nismo exhaust with a test pipe and got a gain of 1 HP

which shop? any dyno graphs to prove/disproove this?? I find that hard to believe....

shabarivas · 04-17-2009, 10:42 AM

why so hard to believe? was there a tune done? there are MANY cases where Z and G owners find 1 2 or even -1 to -5 hp increase...

jaxchuck · 04-17-2009, 11:11 AM

I left off the name of the shop/vendor since they have their own dyno but sell the Nismo exhaust and were kind enough to share their results with me when I emailed them privately about my exhaust purchase. They also told me that without a testpipe they expected a 5-10 HP gain but had not done a dyno on the Nismo system with stock cats to back this up.

I find it hard to believe Nismo's CB would not have ANY gains or loose power. Did a G owner test a Z's Nismo catback???

Are you saying the Nismo catback's expected gain (per the shop) was 5-10 HP? I guess I am curious to know what the Nismo catback alone would do. I see no reason to expect it to be anything less than the 10-15 HP gains other CBs are getting.....

Maybe I am missing something...

I ended up buying the NISMO exhaust at purchase. I had to wait a week for the system to come in. I noticed a significant difference from the stock to the NISMO.

But really to make the plumbing clean and crisp HFC are a must and are pending for me but I am holding off just at the moment.

I am waiting to see which HFC - Cobb tuning use to create there up and coming remap device. Matter of fact I am holding off on any CAI for the same reason.

I like the NISMO exhaust, they look like cannons from the rear. Love it. Sound is just perfect.

355890 - What difference did you notice? Was it Power? Sound? or Both??

Minicobra1 · 04-17-2009, 03:25 PM

Idle, you can barely tell a difference, driving around normally and shifting at say 3500 rpm it's just a slight increase over the stock sound. It's very mellow. As well as cruising steady rpm, street or freeway, again very mellow bump in tone/sound over stock. There is a big difference in sound/tone at WOT, it really comes to life, not super aggressive, but you know it's not a stock exhaust. I haven't dynoed yet, but my gut feeling is that it added another 10-15hp above 5K RPM and Peak. I'm currently trying to decide on HFC's, I'm leaning toward the Berks, but wish I could here someone that has a NISMO + BERKS.

I too have the exhaust. Fit and finish is fantastic, but it is like others have said, a bit too quiet around town. I do hope this exhaust does not have issues with HFC's, my 350Z Nismo catback cracked 3 different brands of HFC's, all within 2-3k miles of each other. The Y-pipe was the culprit, and this one looks similar in build/style. Someone want to be the first tester with this?

Power = Yes I believe so...especially when getting the revs up, but then again it's like the cake without the icing. HFC's are a must for proper power increases with a remap. So I would consider it an incomplete set-up at the moment. But like I said I am interested in the bolt-ons that Cobb tuning will use to create this remap.

Sound = To me and what I liked about it...was it had a more European sound. Which is what I wanted. I am used to European cars. I wasn't looking for something overly loud and humming in the cockpit. Remember it is a very small area.

So if you want something loud and crazy then this exhaust is not for you.

Excellent! Just what I am looking for in an exhaust. I don't want it to be annoying, just in case I have a client or my boss with me when he is in town... But do want it to wake me up at WOT.

Great. Thanks for the feedback guys...

Excellent. I will be getting the BERKS. How much did you pay for the install of the HFC portion only ( labor ).

Also I assume no joining problems with the NISMO to speak of????

The nismo only gains about 5 hp.
