New Aftermarket Exhausts!!!!
 

This thread will be dedicated to all aftermarket exhausts available for the new Z34. I will be trying to focus on products that either have not been introduced to the community yet; or at least shed a little light on products that have not received a lot of exposure here at the370Z.com.

The first exhaust that I would like to focus on is from a company called MCR. This is an amazing exhaust that deserves to be the first product posted on this thread. Many enthusiasts, especially Nissan owners, have at least heard of MCR.

MCR is a relatively small company that has won a few awards in the past; one example is during Touge runs on Best Motoring International DVDs with their famous R34, and they are always looking to push the envelope in order to see what can and what cannot be done.

For this particular exhaust, MCR sourced the services of Nippon Steel; Nippon Steel is the company that fabricates the exhausts for Amuse/Ericsson, Tracy Sports, and a few other reputable companies.

The Front pipe portion is fabricated from SUS304 stainless steel; the rear section is full titanium. This exhaust saves 13.4kg (29.54 lbs.) in weight. Obviously an exhaust of this quality will be providing significant power gains, how much exactly I am not sure at the moment. The exhaust is fabricated with the main piping diameter being 60mm then flowing into two 115mm tips (double tube finishing).

As I mentioned earlier, this exhaust by MCR and all of the Amuse exhausts are fabricated by Nippon Steel. Of course each has their own unique sense of purpose and functionality but they are all quite similar. The reality is that we try to keep our inventory as versatile as possible and one of the most effective ways to do so is to feed off of the opinions of the members of communities such as the370Z. Please let me know what you think.

Here is another exhaust fabricated at Nippon Steel.

I have seen this exhaust scattered throughout the forum boards, but I would just like to shed a little bit more light on this unique product.

This exhaust is designed by a pioneer called Powerhouse Amuse. Powerhouse Amuse was one of the first aftermarket car companies to source the services of Nippon Steel. Amuse is an extremely versatile company that tunes wonders with many different cars, ranging from S2000's, to 350Zs, to the new R35 GT-R. To this day Amuse is still standing strong as one of the leading tuners in the industry.

With weight savings being among the best that you will see, power gains being extremely significant when compared to other exhausts; this is top notch. When customers purchase an exhaust from Amuse, they are offered different options to modify the appearance of the exhaust via gradation finishes in order to express their personal tastes.

Here are a few pictures including dyno read outs. Please let me know what you think:

It's damn sexy. And light. But, WILL IT MAKE POWER? And will it be reasonable to drive with every day?

Having been fabricated from Nippon Steel, it is a definite that this exhaust will make significant power. This same exhaust design for the Z33 had a decibel rating of 92; knowing this, I would imagine that this exhaust will be daily drivable as well.

That is one sexy exhaust!

Great work!!! You always seem to amaze me :hello:

Looks Nice
 

Please post up the comparitive dynos between the OEM and this system as soon as you are able.

Thanks!

To my knowledge, MCR hasn't released dyno charts at this point in time. This exhaust has been announced but hasn't been made available to the public yet.

Once pricing has been determined, I believe they will release all information about this exhaust; once that happens I will definitely be updating the enthusiasts of this community.

Here is an exhaust by Sunline Racing.

Sunline Racing is a company that has a lot enthusiasm for many different makes and models and really excels in the Nissan market. Fusing functionality with aesthetics, Sunline Racing is able to fabricate products that appeal to a wide array of different tuners.

This exhaust is a full titanium exhaust that uses shorter canisters in order to produce a louder decibel rating. The main piping has a 60mm diameter with two 120mm tips.

Today I would like to talk about the Zele titanium quad tip exhaust Type 1. This exhaust has a very innovative design as well as wonderful quality; which coming from Zele, why would you expect anything less?

Zele is a company that is well known for their distinct methods of tuning. Zele started as a company who purchased vehicles modified and tuned them to what they believed was best, and then sold them to the public as a whole car.

After many years of pushing the limits of tuning, Zele decided to broaden their horizons to new areas of the industry. Most enthusiasts know of Zele through their incredible breakthroughs and distinct products for the R35 GTR and the new 370Z. Just by looking at the current products that Zele has offered to the public, you can tell that their classy style is one that will outlast the trends.

This exhaust is a perfect example of Zele form and functionality. This rear section exhaust is full titanium with a gradation finish that you will only find in Japan. This intricate quad tip design is meant to increase the flow and distribute air evenly while giving it a more exotic look for aesthetics. As you can see the canisters are relatively small in size which means that the sound will be noticeable from a distance. These canisters, when fused with the quad tip design and thicker titanium walls, grants an overall tone that is deep and beefy, and still allows lower decibel ratings for daily driving.

In the end, a well designed exhaust that improves the car in all aspects: weight reduction, performance, and aesthetics.

That looks real nice! Will this fit with the OEM rear bumper as I've only seen this exhaust matched with the Zele kit so far?

So much quality in these exhausts.

I cannot say with 100% accuracy, but from what information I have gathered the exhaust should have minimal fitment issues (if any) when mounted with the OEM rear bumper.

You can expect only the best quality from Japan.

-Hunter

Here is a rear shot of the 370Z with the Zele exhaust for everyone's enjoyment.

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:

-Hunter

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?

-Hunter

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.

haha, this makes me laugh...really :shakes head:

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.

-Hunter

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.

-Hunter

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 :tup: .

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.
