I fail to see how the use of Nippon steel will matter on the power output. The cross section of the tubing, bend radius, and lengths can all be achieved with a wide range of steels ranging from a cheap ferritic like 409 to a Ti stabilized 321 austenitic. The choice of material and service environment will dictate the longevity of the final product. This assumes a skilled craftsman is doing the work.

All of the above may be purchased from a multitude of mills in numerous countries.

You bring up a good point.

You are correct about how the material of the item itself determines very little of the power gains. Looking back now, my previous statement may not have been the best choice of words. The point that I was trying to make was simply this:

These exhausts have shown very nice power gains. What makes them more impressive is the fabrication process that is invested in their quality; from the method of welding, to the thickness of the piping, to the material being used. All of these factor in to the overall design of the exhaust making them lighter and stronger. This results in significant weight savings in order to allow the owners to unleash the power that was previously held back from all of the additional weight.

Also, yes these exhausts may be purchased from different companies. However, only a few are direct, authorized distributors for companies such as Amuse, Zele, and MCR. In order to guarantee more accuracy, and better lead times, it is best to order from a distributor who is direct with these companies.

My apologies for the mixed signals and thank you for your input and knowledge. No doubt that this will now be even more of an educational piece for the members of this community. :tup:

In the end it all depends on your personal taste. I myself prefer the exhaust by Powerhouse Amuse. The bends, welding, gradation finishes, and cutting are all very pristine. Some people like the quad exhaust system because it is different and innovative.

What do you look for in an exhaust?

This exhaust is designed by ARC.

ARC is very well known and respected in the Nissan and Mitsubishi community. Most of their products are made in house which helps to further ensure the quality they try so hard to represent. Specializing in mostly performance parts such as exhaust, forced induction, and cooling components, ARC is able to combine performance with a nice bling factor and they combine it well.

This exhaust is full titanium with double tube piping on the tips. Of course no ARC product is complete without the ARC labels. ARC products are always recognized about a mile away from the elaborate labeling of their company, which is made clear on the mirror image of this exhaust.

As I have stated in the previous entries, Amuse is my favorite company but this exhaust is a close second. Most likely there will be more Amuse exhausts on the road than ARC exhausts simply because ARC pricing has been known to be in the higher ranges.

This ARC exhaust is able to represent some of the most exquisite styling, functionality, quality, and rarity that JDM tuning has to offer.

I cant help but chuckle a little when reading through this. In the LSX community, nobody really cares how exhaust looks at ALL. It all comes down to these aspects, in this order generally:

-Dyno-proven power
-Sound
-Ground Clearance

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 :).

How much do these cost ?

Catback's are merely for sound in the end?only? What are you talking about dude? NO disrespect, but you sound like the ricer. It's possible to gain more then just 5-6whp from an catback especially if there's some backpressure to relieve and some tune. 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

Your back pressure doesn't generally start at the catback. I hate to tell ya...and as soon as you start talking about a tune, you're adding a whole new element to the equation, and proven my point.

Im talking catback ONLY, no tune, nothing else. You wont gain much at all from it, more than likely.

Now, a header-back exhaust + tune? I'd certainly hope to see some competent gains from that.

Yes backpressure doesn't start from the catback, but the catback is part of the cause to backpressure. It all depends on the car your working with you can add headers,tp, a catback+tune like on a civic and won't see much gain. The statement that you can only see 5-6whp and just for sound on a catback is not true. For example some turbo'd cars see around 15+whp w/o tune. I think the new Z can probably put down more then 5-6whp with a catback+tune.

As for me, Good sound is the most important aspect, with power gains a close second. I've just ordered a 370Z on Feb. 16th and I want to put a good sounding exhaust on it. On my current 350Z, I have had various exhaust fitments on it, and by FAR the best sound was with the Kinetix hi-flow cats and the Nismo Exhaust. A lot of the time I just didn't care about the sound system, just wanted to hear the engine & exhaust. What does everyone think would have the best sound on the new 370? Thanks, Phil.

Sigh, maybe I should have been more specific.

Im not talking ANY car here, Im talking the 370Z, which is a non-turbocharged vehicle. Backpressure isnt nearly as much of an issue. Hence why, a simple catback and NOTHING else, will make very little difference.

I'm fairly sure there's already some dyno graphs showing very small horsepower changes on full exhaust setups WITH test pipes and no tune. Like, 8-10 WHP. Ditch the test pipes, I bet that will drop even more of course.

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.
