Thanks for all the info! In the US the 370Z is around $30-40k new with some base models even in the upper $20k range. Hopefully this exhaust will be cheaper than $6k :tup:

The system is completely made in Italy. A LOT of JDM parts are made in Taiwan or China (HJS, Invidia, Tanabe etc) so they are cheap, and I have to be honest, (sometimes) they are well made, as the workers are very cheap they can afford to have more people, for example you can have a single worker that makes the same TIG welding on the same part all day long...
They usually are too loud in full system form, and the headers are often nice looking but fragile.

Anyway, the price of 6k is just an indication, based on the cost of similar system from Superprint, for example the GT3 system has step-design headers, HJS 200 CPSI cat and a rear exaust with black tips...it made 465 Hp on the mk2 3.8, that had 446 hp from standard, and that's on a higly strung NA engine, JUST with the exhaust...and it's around 7k.

I have no idea whatsoever what this system could do on a SC car, as the headers are a lot bigger (we're talking 42mm for the first ~150 mm, 48 for the rest of the primary pipes, with soft variations between..how big are the F.I.?), and the cats are the best in the world!

Another thing, how much is a new 370Z in the US? because here in Italy it's 41.000 Euros-->58,000 USD for the Coupè.

Consider just this, the previous full system developed was for the Mercedes SLS AMG (that's a 190k Euros car!), and it was made with the same philosophy. I've seen the dyno charts: standard car 581 HP and 640 nm. Full Exhaust 603 HP and 700 nm..but that's not the full story as at 3800 rpm there was a 55 hp increase! Hamann is going to offer this system in his catalogue (Supersprint makes all the system for Hamann, Hartge, Carlsson, Lorinser, Geiger, Techart, AC Schnitzer etc...)
Here you can watch all the recent cars, SLS included:
YouTube - ‪Supersprintcom's Channel‬‏

I tried to read this, but once it began to sound like you were even trying to justify anything close to $6000 for an exhaust my mind just shut off.

I really don't care if it is made from the blood of unicorns, it's an exhaust. Let's break down what that means: BENT PIPES WELDED TOGETHER WITH A MUFFLER. You can try to pretty that up all you want, but in the end, that is all that it is. It isn't going to make much (if any) power over an invidia or even a damn ebay exhaust.

The only reason someone would buy this exhaust is to say they have it and make others feel poor. That might work for them in the euro car "the more i buy the bigger my penis gets" land, but I imagine among level headed people this concept is just stupid.

Hell. even half the cost is still overpriced. You can have a local welder make you a Ti exhaust for under $3,000 (well at least I can), why would anyone pay more for less of a product is beyond me.

Jamaica 06-15-2011 03:56 PM

I guess Amuse, HKS and Greddy are cheap exhaust now.

Econ 06-15-2011 04:22 PM

gaveup,

some people here are spending $5k + on wheels.... many might find this over the top on a $30k car. and forged wheels are just a big piece of metal slamed into a different peice of metal, right?

so, although i think its steep i can see some people buying this....

:iagree:

Some will buy it just to brag that they have a super expensive Italian exhaust. I would much rather have an expensive Italian supercar/supermodel :bowrofl:

Would be nice to get some "facts" directly from the manufacturer, as we do with several of the exhaust manufacturers on this forum. Info from some random dude in Italy is not going to cut it.

so its only a 10 CRANK Hp gain?

so its about $1k per 1 WHP gain?

Facts:
This exhaust weighs about the same as any cheaper 370Z aftermarket exhaust
This exhaust makes no more power than any cheaper 370Z aftermarket exhaust.

Is the weight the full weigh loss (both long tube headers & exhaust)?
Good power gains, but no more than any other combo on the market.

Honestly it is hard to tell since he is quoting flywheel numbers and there is no why they can know for certain it is making XHP at the flywheel after the upgrades.
Hence the need for it to be put on a dyno prior to upgrades & then post upgrades.

ClemsonWill 06-16-2011 08:52 AM

$6K! 10 hp gain. I'm not impressed at all.

Gardus350z 06-16-2011 09:37 AM

10 hp?

It's 335 standard, 345 catback (almost the same with the Invidia Q300 and the Supersprint), 365 with headers, cats and catback...that's a 30 Hp gain, I don't know where did you get 10 Hp.
There's a consistent increase in torque too!

Anyway I have the dyno charts of all the runs, with power loss (measured everytime on the MAHA brake dyno), WHP, correcting factor etc

I think a 30 hp flywheel (corrected with EWG factors) increase is pretty good!
It's around 24 WHP but the run with the full exhaust was hotter, with higher humidity and lower ambient pressure...you'll see everything as soon as I have the pdf files.

Coming soon:
Dyno chart
Video revving
Video of full acceleration and flyby.

I think it sounds great...maybe a bit too much for the road, but no drone, the sound is awesome.

theDreamer 06-16-2011 09:39 AM

Why do you keep comparing your exhaust to the keep sub 1,000USD exhaust systems?
Try comparing it to Powerhouse Amuse, Top Secret, Fast Intentions, etc. Not a very good selling point that you want to sell this for 6,000 and yet all you have done is compare it to the cheapest exhaust systems on the market.

Gardus350z 06-16-2011 09:51 AM

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.

theDreamer 06-16-2011 10:07 AM

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.

Econ 06-16-2011 10:11 AM

flawless victory

Gardus350z 06-16-2011 10:32 AM

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

theDreamer 06-16-2011 10:37 AM

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.

phelan 06-16-2011 10:41 AM

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:

Gardus350z 06-16-2011 10:44 AM

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.

Econ 06-16-2011 10:45 AM

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

Caravanshaka 06-16-2011 10:49 AM

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.

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

Gardus350z 06-16-2011 11:05 AM

I agree, different dyno gives very different results, especially if of different type like the inertial F.I. dyno and the Supersprint brake dyno...
Maybe an acceleration time in the real world would tell us more, like an in gear acceleration video!

I still think it would be interesting to see the air intake temperature and ambient pressure and humidity on the F.I. dynos.

It will be very hard to have both systems toghether as they're not popular here in Italy, and Supersprint won't probably sell in the US because of the price. It would be very interesting.

how come a SuperSprint for the BWM 650 is $3,584, and for a 370z around 6k?

different company?

hmmm...

6k for this!

or...

8k for a gtm tt!

the choice is simple...

FastPaced 06-16-2011 10:42 PM

Why has this thread gotten this far in regards to price? If the system has a price tag of 6k, then so be it. Yes, many would like it to be more affordable but the fact of the matter is that it is what it is and that being a SuperSprint exhaust.

Like Econ stated, several people spend over 4-5k on wheels alone. There is absolutely no gains from cosmetics unless it assists the aerodynamics of the car.

This exhaust, just like any other "higher-end" exhaust, or anything expensive because of a "Brand," is marketed towards the people who want to or don't mind spending that amount of money.

For those concerned with power gains, wait for Dyno charts or do a little more research on your own and see what you can find, if there is any information from another person or SuperSprint themselves.

I'm just saying, this isn't the first time you see a steep price tag on something you may believe is not worth it. For example, some people spend thousands on watches and no matter how you justify it, at it's most basic function, it just tells time.
