All cars are different maybe if you're talking about a civic that statement might be true. It's just N/A cars don't see as much gain as a turbo'd car because they don't create as much backpressure. I don't know about you but I like:

-Beautiful seemless weldings
-Build quality/presentation
-Perfomance gains
-db levels appropriate for street use.

I'm not rich, but I don't mind paying for quality products.

-Fit and finish

How is he the ricer? You obviously have no clue about the VQ. All these cat-backs do give a mere 6-8whp MAX! You are also arguing something that initially wasn't mentioned. Mightybobo is talking just about purely a cat-back...not a cat-back+tune (what you are arguing). Of course a cat-back + tune will give you more than 5-6whp, heck the tune alone will do that without the need for the cat-back. These fancy exhausts are merely for status/sound and weight savings as they are damn light.

Obviously you have no clue about the new VQ it's better and takes better to mods then the old one. I'm confident it will make more then just 5-6whp w/o tune. GTM's exhaust shows pretty good gains on their dyno sheet not sure if that was tuned or not.

Blanket statements (IE, "The new VQ is better and takes better to mods" - you think its going to respond well to ALL mods, equally as well?) aren't good. Technologically this motor isnt that different from the previous - just slightly more displacement. You honestly think its going to pull some magic numbers out of nowhere for simple mods?

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.

I see all this titanium this, "only the finest from Japan" that - people need to realize there are probably plenty of domestic manufacturers who make the same crap for much cheaper heh. We aren't talking magic here - the designs are all similar. Mandrel bent steel or titanium, going into mufflers (which are probably very similar). The long and short is, you wont see huge performance gains on a catback. Ever. Maybe a 5 or 6 wheel horsepower at most. Ricers expecting to get 20+ horsepower from their catback, may as well abandon all hope right now.

Until you start working the entire system (headers back), the catback is merely for sound in the end. And if you're willing to blow the RIDICULOUS amounts of money that these big name manufacturers want, why not give your local fab shop a try and have them custom make you a system that will probably perform just as well for cheaper? If you honestly think the only place you can get a decent-performing exhaust is Japan, some people need to get their head checked lol. Just my 2 cents

.

I'm glad someone else said all this.
I would add that weight savings in an aftermarket exhaust would be bonus but I'm pretty sure I'll never ask my friends to lay down on the pavement to look at how pretty my exhaust system is... if it can be seen at all with such low ground clearance. Fair price for the performance gain is requirement number one.

The Nismo Z gained 18 HP with a new exhaust and tune.

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.

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, 06:15 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.
