simply for looks. Personally i dont really like the single exhuast exit because the Z's rear bumper has a cutout for 2 exits. If the car had a bumper cutout with only 1 exhaust exit then i'm all for the JIC Ti single exhuast. Not only does it look nice but the weight savings is worth while by itself.

So I'll just tell you.
In my opinion the optimal setup for a N/A 350Z is an exhaust system with equal length headers, test pipes, and about a 2.25" - 2.5" true dual catback portion of the exhaust.
Second place (again, my opinion) would be to replace the true dual catback with a y-pipe to about a 3" collector and single muffler.
The nismo exhaust has a y-pipe going to a 3" collector but has a dual exit muffler. If anyone can tell me the purpose of having a dual exit muffler on a single exhaust I'm all ears, because I haven't figured it out yet.
So if you're wondering if borla is a more optimal setup than nismo, my guess would be yes.

I love my Borla though and am glad I chose it.

I can't comment on the nismo exhaust since I never had the system installed, but the Borla exhaust was my 1st mod w/ the AEM CAI and I felt a lot more pull over 4k rpm.. Now it is combined with hfc's and headers, the sound is music to my ears at WOT, I do experience some rasp when I let off the gas, but for me it is not an issue since it's not my daily driver. Just remember when you start to open up the exhaust, it will only flow as well as the weakest link... I could not believe the weight and restriction of the oem cats and exhaust manifold...So back to the OP, I vote for the Borla, never had a problem with leaks, has a nice deep note and you will notice a gain...Good luck

Try tuners or performance shops in your area. They'll do anything.
And I agree with Brian...I had the Borla + AEM CAI for a while and it was wicked sweet. I finally swapped in the popcharger due to some bad weather we were having in OR. But overall I loved the AEM CAI more than the popcharger...but I still love my Borla 10x over. When I get my oil changed or take it to the dealer I ALWAYS hear them rev it just to hear it. It makes me smile.

That's proof enough for me that they perform.

I believe the Borla claims of 20HP IS NOT to the wheels and was taken from their original ad. While the number you got for the Nismo IS to the wheels and that nismo number came from the sports Z magazine shootout. You are basically comparing two different things.
Here is the HP numbers to the wheels from Sport Z magazine:
PEAK HP:
1. Borla 8.2
2. Stillen 8.1
3. Injen 7.6
4. Nismo 6.3
5. 5Zigen -3.4
PEAK Torque:
1. Stillen 7.3
2. Injen 5.1
3. Nismo 4.5
4. Borla 2.7
5. 5Zigen 0.2

They are almost the same price (nismo is actually a little more) but borla claims to give you 16-20 horsepower while nismo only claims 6.5. Is borla really that much better? And if so and I get it will it void my 3 year warranty on my 05?

thanks zlleh thats the most useful information I've been able to get on these forums so far. Usually everyone just tries to make some lame joke about the turbonator or refer me to the S**tty search function

so it looks like stillen is the best overall. are thos enumbers considered reliable? are there any downsides to the stillen that you guys know of?

I think they are reliable enough. The comparison test was done by a car magazine that included dynos from all the runs.
As for Stillen being the best, I agree that Stillen looks like the best choice from the numbers. But the stillen exhaust is heaver then the stock exhuast and the stock exhaust is already really heavy to begin with (while all the other exhaust is lighter then stock). So put that into consideration.
I got the Borla purely for sound, the high HP was a bonous. I had the fortune of running into a Zed owner that had the Borla exhaust installed and she reved up her car for me to hear it. I suggest you try to go to a 350Z meet and find a car with the exhaust that you want and ask if you can hear it.

I think the stillen is a good deal. It has a nice design, it's true dual, x-pipe, good pipe size.
If you like the sound then it's for you.
The slight weight increase won't make a difference.
If you're looking for weight savings you'd best go with something like JIC Ti single

its safe to assume, when looking into an exhuast mod, hp gain should never be your number one pripority in choosing unless your FI. Sound is what one is looking for.
When your NA gains will always be in the range of 10-12hp. Basically if you look at the JIC single you will see the configuration very similiar to the nismo exhuast except for the fact that the whole exhaust is made out of Ti and that JIC has weight reduced the design of the heaviest part of the exhuast, the muffler.
So all in all, does the nismo perform as well as the JIC, sure why not maybe 1-2hp difference? Does the nismo weight as much as the JIC. Of course not, and thats where the significant difference and performance comes from. Remeber the JIC weights only 9lbs! The nismo weights what 60lbs? You are saving 49lb! Then if you take it one step further and take out your spare tire and tools your saving 100lb. 100lb is capable of improving your time down the 1/4 by .10 of a second, if not more.

When you buy an exhaust first off make sure that you are going to be happy with the sound, buy the one that sounds the best to you. Me personally I love the way the NISMO exhaust sounds...
Are building the car to race or is for you? if to race then go with something that is super light and maybe think about the future of the car, are going to turbo or supercharge it? If so then look in to an exhaust that will compliment the future mods.
If you are building for you (meaning looks and some horsepower gains, but not to race or track) then just make sure that when you buy something you are happy with and that is not adding more weight then what the stock parts added and you will be looking good with performance upgrades. the weight thing probably won't apply if you upgrade the wheels. Hope this Helps

i just installed my nismo exhuast tonite, mind you this is my second time i installed a nismo exhuast for my car. The first time was on my g35 which i sold along with the exhaust. Now i have a 350z and i had another exhuast. It was a TD and peformed well but i did loose some low end power but made it up in the higher power band. Anyway, i ditched it because i missed the good ol' vq note. The only other exhuast i would trade my nismo would be the amuse Ti. That is the howtness
Now that i have my nismo exhuast back with that beautiful vq note im happy as ever. As performance wise, i gained back my low end power even with test pipes which are known to take away low end power. Now my powerband feels SOLID all the way to redline with some empahsis on the mid range power but that might because i have the spacer and mrev2. With my TD exhuast, it lacked the low end torque which made me feel like i was driving a civic up until i hit 4k and i feel a small boost of power and it pulls all the way to redline.
As tempted as i am to go get dyno comparison from TD vs Y-pipe exhaust i will not waste my money for i need to save up money for my upcoming install =)
PS: I forgot to mention that HKS claimed that their exhuast gained 14hp and 1x of tq. But they never gave specifics such as what conditions, was it stock, what kind of dyno, etc. I bet each company that sell exhuast can expolit their numbers as well as the next so be warned! Lastly, if you do a search IE: HKS you will see that 90% of the thread is concerned about the sound it makes not the power it gives.
end of my .02

so is the consensus that the extra weight from the stillen WON'T offset the performance gains? Because I actually like the way Nismo sounds a little better. But stillen is my second favorite in sound i think and if it creates better performaance (especially with the tq numbers quoted above) throughout the power band then thats the one i will go with.

I gained a solid 33 whp and an astonishing 41 TQ with it. It was like a whole different car.
Don't ever put your turbonater in backwards! lesson learnt.

In my opinion the optimal setup for a N/A 350Z is an exhaust system with equal length headers, test pipes, and about a 2.25" - 2.5" true dual catback portion of the exhaust.
Second place (again, my opinion) would be to replace the true dual catback with a y-pipe to about a 3" collector and single muffler.
The nismo exhaust has a y-pipe going to a 3" collector but has a dual exit muffler. If anyone can tell me the purpose of having a dual exit muffler on a single exhaust I'm all ears, because I haven't figured it out yet.
So if you're wondering if borla is a more optimal setup than nismo, my guess would be yes.

i believe they made it dual exit just to fill the two holes in the stock bumper. it was made by nissan so of course they would make it to fit exactly to the car. it follows the stock setup.
