This literally made me :rofl2:

Hey, I'm not saying is the best exhaust in the world, calm down!

In fact, a few posts ago I asked if there is any dyno chart of some full exhaust, too see where we are with this one! Could you please link them, as the forum is huge and it's hard to find the right charts and the right products.

Guys, I'm not trying to sell anything, but please forgive me some national pride in an Italian company that i think works very well.

Fast Intentions LTH plus exhaust - http://www.the370z.com/intake-exhaus...ders-here.html (+30WHP & +20TQ)
Powerhouse Amuse Exhaust - http://www.the370z.com/intake-exhaus...vids-dyno.html (+15WHP & +8TQ)

Both system much cheaper than yours and providing equal power gains or more. Both systems weight less than stock by a large margin (25-35lbs under stock). While I think your system looks very promising, you must understand this is not Porsche or Mercedes AMG so by pricing this system so high you are eliminating any possible customers.

flawless victory

Are those from a inertial dyno or a brake dyno? You know that on a inertial dyno you can't measure the power loss, and that depends on a lot of factors, like the temperature of the tyres, the weight on them, the pressure, the transmission temperature etc...the WHP is accurate but it depends on these factors.

As F.I. says, if you haven't got the same conditions (where are the values, like temperature, pressure etc.?) the value themselves are not very reliable...

On their charts I see:
stock: 280 hp
exhaust: 310 Hp
Is that WHP? because our car was:
stock: 261.7 WHP
full exhaust: 284.3 WHP
So it's a 22.6 WHP increase.
BUT the conditions were different, plus the stock run had 69.3 hp of power loss, with the exhaust these became 71,7 (as the power loss is a % of the flywheel power, is normal to see an increase in it too)
So what's the flywheel HP on the F.I. car?

I see a few irregularities in the F.I. chart:
It starts at 2700 rpm. We've seen a valley in the torque curve at 2400 rpm but you can't see it in that chart.

I don't want to start a dyno war, just asking.

We went from 362 to 382.5 nm

I am done, you just are trying to put your exhaust on a mantel, there is not point in this debate. Good luck with your exhaust system.
If you want to knit pick, then lets see your facts, so far I have nothing from you.

Nobody is refuting that those are at least decent numbers. Let's not get into dyno politics in this thread.

I think the sticking point for many of us is that we fail to see a $6K stainless steel exhaust system selling very well. That's basically around 20% the value of the car, why would you do that? I get poked every so often for buying an expensive exhaust, but at least Amuse gave me a pretty and stupidly light titanium (if somewhat ill-fitting) exhaust for it :ugh2:

I've seen the F.I. video...is it caused by my speakers or is there really so much drone at low rpm? It sounds similar...the Supersprint seems a bit raspier and wilder...you'll see the videos!

I got it, it's too expensive...please could we continue to analyze the technical differences and the performance increases? What are the diameter sizes of the F.I. headers, for example?

Dreamer what facts?

I'm trying to understand if 365 hp are good or not with a full exhaust by itself.

I don't get why so much hostility around here. I haven't seen a lot of 370z, and especially not many exhaust systems for it, so I'd like to know where this system is placed on a performance level.

yea, i'm sure the exhaust will perform on par, and sound great, however the main argument here is the steep price.

:tup: for a nice exhaust regardless

I can buy an altima for 6k, nuff said

The only full system I've seen with dyno charts is the F.I. and the results seem similar...the design is not so different, it would be very good to have a few direction on how to use the charts and make a comparison.

there's a lot.

You cannot compare dyno to dyno.
You compare gains as long as they used the same dyno and similar conditions for all testing. Which Fast Intentions uses the same car for testing and the same dyno, and as close to similar ambient conditions as possible. Trying to compare your dyno results to another is not a 1 to 1 science, which is why you post up bone stock runs and then modified and we get about 80% similar comparison.

This.

Now if you got a F.I. system next to you, and dyno'd on the same setup, on the same car, in similar ambient conditions, that would be interesting.

indeed. a lot of ppl run the F.I., thus if you were able to run both a F.I. and a SuperSprint in the same day on the same car, this would be intersting as phelan stated.

or at least a car with F.I vs your car with SS. supporting mods would have to be similiar as well
