haha, this makes me laugh...really

GTM's exhaust testing had multiple dynos, and you'd only understand it if you've ever read a dyno graph. Their huge like, 21 WHP gain not only factored in the catback + test pipes, but also some timing adjustments (tuning, kinda). Either way, its NOT just the cat back. Im also skeptical about this specific graph, because its the ONLY one not showing AFR's...did this one have some timing adjustments? According to them, no...but I wanna see those AFR's.

Either way, their baseline dyno, and their cat-back only dyno were 10 DAYS apart! What if the weather was considerably cooler on the cat-back dyno day versus the stock one? Or less humid? Until I see a dyno of a stock catback to aftermarket one within a VERY small time period (couple hours at most), I don't buy dyno-proven too much heh. Oh, btw, their stock exhaust vs. cat-back only exhaust dynos showed a 10 WHP increase. But 10 days apart, that doesn't mean much to me at all.

I don't say their exhaust isnt a good one, by the way. And a small disclaimer, my 5-6 HP was a random shot in the dark, I didnt know how much "power" the 350Z's got off a cat-back only. So who knows, maybe its 10 or so. Either way it isn't much, and its just a piece in the puzzle to a full header-back exhaust that will make a fairly big difference.

agree.

I appreciate all of the different views and opinions that are being expressed in this thread. This thread was initially intended to offer a service by educating all of the different possibilities for the 370Z. I myself do enjoy JDM products but I will agree that there are many amazing exhausts with great performance quality fabricated here in the states. In the end, you are all justified in your claims mainly because that is your taste, your style, that is what you prefer. It is all a matter of opinion and perspective and I respect and I appreciate every single one, as I am hoping everyone else will.

Getting back on track, I will continue to inform this community of all JDM exhaust possibilities that are available and will be available in the future.

Central 20 is another company that focuses mainly in the Nissan market. They offered many popular products for the Z33 and are now taking a shot at the new Z34.

Here is a picture they just released information about their new exhaust manifold for the new Z34.

okay... so what's so special about Nippon Steel?

I am glad you asked.

Amuse and Nippon Steel offer something called STTi. Basically it is Super Tough Titanium. This material has proven most effective with the new R35 as most people are aware of the immense amounts of heating the R35 produces throughout the exhaust system. Most titanium exhaust systems, as they increase in temperature, they become more brittle, more fragile; Exhausts from Powerhouse Amuse & Nippon Steel are not as prone to cracking or bending. I do not know the full specifics of STTi, I just know that this material has a longer life span than most titanium exhausts, and yet it is among the lightest exhausts at this point in time.

But, that really didn't answer the question he was REALLY wondering heh. You said:

"Having been fabricated from Nippon Steel, it is a definite that this exhaust will make significant power"

What about Nippon Steel will make more power than any other exhaust?

My apologies if that wasn't the answer you were looking for. Please allow to try again.

Going back to the whole STTi concept, simple physics explains that as materials heat up, the molecules expand, making that item more flexible, more brittle, and more malleable. This also creates more friction. The more friction an object creates, the more power it loses. To my knowledge Nippon Steel and Amuse are the only ones at this point in time who produce their exhausts using STTi. If you add these lurking variables in with all a few other factors of this exhaust, such as lighter weight and less bends, this exhaust will not only create more power but will also free up existing power that you couldn't take advantage of before due to dead weight.

Most people ask the question "how impressive can this exhaust really be?". I can try my best to explain it as long as people are willing to listen. In the end, I am simply enlightening people on different options for their Z. Please let me know how I may better assist you.

I believe what Nippon has developed is a more sag and creep resistant alloy. If that is the case then the original shape of the components would not change as much at high temperatures. This could aid in maintaining the original power of the package. Whatever that level was.

As to friction in the cystallographic structure at elevated temperatures causing a recordable loss in power I'd have to say that is a pretty week limb to be standing on.

Good point and great facts

.

The only information I have to go off of at this point in time is the information that has been provided to me by our suppliers. I have witnessed the same quality from Nippon Steel on the R35's, and based on what our R35 clients who purchased Amuse have told us, there is no better exhaust with better gains than the Amuse STTi. OF course the 370Z is a completely different animal so I cannot say that the results will be as impressive as the R35.

Having witnessed Amuse and Nippon quality in person and having experienced the results, I can only go off of past experiences which have not steered wrong yet. Based on my past experiences exhausts from Amuse and Nippon produce some of the best power, help shave off some solid amounts of weight, and IMO look good doing it. I guess in the end it all comes down to personal perspective and I might have been to over the top in my explanation because I tied in my personal opinion in with facts which can get kind of gray.

I think, maybe its more appropriate to say that...possibly the developers are (hopefully) going out of their way to ensure their product makes very solid gains for the money, because nobody is going to pay a ridiculous sum of money for a product that makes mediocre power. So,may as well engineer the product to make high gains so that people feel justified in spending their large sum of money on their product in the end, right?

It sounds like we both agree that if you purchase an exhaust offered by Amuse, you will be satisfied and justified with your purchase; it will have longevity, and IMO good sounds and good looks. Based on their dyno graphs, I would imagine that Amuse's exhaust should produce some of the more significant gains that you will see from an exhaust for the Z.

In the end it all comes down to preference which you and I seem to have found common ground on.

Here is a picture of the dyno results from Amuse. As you are aware it is measured in PS so the results will be a little off.

using an online converter this comes out to 305.95 rwhp and 254.2 rwtq....

This IS HUGE!

BPAuto · 03-23-2009, 07:15 PM

Amuse has released their new STTi R1-Extra Exhaust as well as their high flow cat with front pipe set. This exhaust is made out of full titanium. I cannot say with 100% certainty but I believe the Amuse cats and front pipe are forged out of SUS304 stainless steel.

how much is the pricing on the amuse? I have bought with you guys before when I had my s2k lol you guys help me get some wicked offset volks for the S
