Umm ok noob...? Any racer rather loose weight then gain HP. So calling him a noob is just . If you loose 5lbs on your exhaust, 5lbs on replacing all the plastic on the intake, new down pipes your probably going to save 15-20lbs. In the 1/4 mile you might shave off a 1/4 of a sec which is a lot. so 10lbs on a 2 ton car is actually a lot. I hate when people bash others...lets be open minded on here.

Normally a consumer listens to the person selling them something and takes there word. Since the guy that sold him that "lied" or whatever now he is less credible and so is the company. Take it for what it is worth

 

20lbs of weight isn't going to make a remotely noticeable difference.

There's one best exhaust for the 350Z. I didn't know that.

 

Greddy Evo tt sounds incredible

 

aparently you didnt take anything from what I stated. The main point was loosing weight is more valuable the gaining HP.

 

I would be supprised if losing 100lbs would yield any more than a .10 sec improvment in the quarter mile.

 

100lbs would make a rather large difference, actually.

 

100lbs is actually a lot. Run the 1/4 mile with a full interior and then run again with the passanger seat out

 

Losing weight is certainly a viable alternative to simply adding more power on, but I think he's getting at the fact that 20 lbs lost weight isn't offsetting the gains you'd get from installing a heavier true dual. As others said...with something like 100 lbs, that would definitely be a whole other story. That's like removing a medium child from your car

 

It is better to remain quiet and thought a fool than to open mouth and remove all doubt.

Ever heard of Google? The web is full of these calculators. They are not exact to the 1/100th of a second, but they are all in the same range, and the relative times for different weights are really close: 100lbs reduction will get you about one tenth in the quarter. Plenty of people on this board that run their cars at the track will tell you the same thing.

Good sarcasam.
Good point.

1/10th in the 1/4 mile is actually A LOT!

 

Really? When you're talking about a car that runs a 13.1 or a 13.0, I'm sorry, it's not alot Perhaps when you are talking a car that ran an 8.0 an then runs a 7.9, that's alot. In slow car math, if you can tell the difference between a car that runs a 13.1 and a car that runs a 13.0, you must posses the hand of god quite honestly.

As far as working in retail, they say a salesperson is the easiest person to sell. Not surprisingly, you were sold a system by a comission salesperson who sells a somewhat limited range of products, and they likely sold you what they make the most profit on. Nothing necessarily wrong with that, as the HKS, Greddy and Stillen (those are their top 3 brands) all produce similar "gains".

The exhaust you were sold works fine, and is well made...it makes no more, nor less power than ANY other exhaust out there. The differences of course between them all are weight (Stillen is heavier than stock), and the quality of construction and sound.

 

Regarding dual exhausts, I am considering the Borla and Fast Intentions.

I want something with the power of a dual, the weight of a faux-dual (not a single), the harmonic sound of an x-pipe, and the looks of something classy (not HKS style).

Do the resonators in the mid section of the Fast Intentions exhaust act as an X pipe, or are the pipes separate within that? I know the Borla connects in the final muffler, but does it connect before there at all?

Sorry for some newb questions...
And anybody have the weight on these 2 systems compared to stock?
The AAM 2.5'' dual looks/sounds nice, but I couldn't tell if it had any x-pipe, and it only saved 6-7lbs (Not looking for some titanium 5lb system, just a few lbs can't hurt).

Impressions comparing these 3?

 

The FastIntentions middle piece is a magnaflow X-pipe

 

Does it make me God when I can easily feel a large difference between a full tank of gas and a nearly empty one?

Seriously, sometimes people here are too quick to tell someone how and what they should be feeling. I feel weight changes in my car instantly, whether it's my 200lb cousin, or my 105lb girlfriend, or a 112lb tank of gas.

 

my bottle takes up 4 the tq loss And is the best sounding exhaust TO ME. I have had- EvoII, Pro-1, Xo2, JiC, Turboxs and 1 more but cant remember
