Z34 Silencer kit 18000-NZ2-K000 ¥273,000 (including tax, you install and labor is not included.) Very limited production run with reservations taken now; shipment after production run.

That sounds and looks phenomenal. What's the conversion in dollars?

edit: It's about $2800 bucks I guess

:drool: :eek: meanest exhaust on the z34! It's a great piece of work. Great find, socal!

With the current exchange rate, $2791.41.

Btw, looks beautiful, sounds mean.

Wonder if that sound clip is through the bypass or through both sets of mufflers. Sounds good, but thats pretty much all I like about it. Looks really heavy.

everything looks great until you get to the tips :icon08:

What is that exactly?

I do not believe those two center pipes at the rear are cutouts. I have written Saclam about them and we will see if they reply. If you trace all the blogs regarding Saclam, they are basically enthusiasts who do things for other enthusiasts as these exhaust are being fabricated for just a few interested parties.

Definitly a work of art, except why the pep boys extreme ricer tips ?

Other than that, sounds beast!

Saclam invested a lot of research into resonating sound waves and air flow. According to their results, this design, however ricey, actually provides functionality and sound to Saclam's standards (which are high standards). First time I saw this exhaust on a Z33 I thought the same thing you did :rofl2: . Then I heard it :bowrofl: .

Now that sounds fantastic.

Neat sounding exhaust. Not to fond of the tips. BUt if they help achive the sound :D

Look like they are making headers also.

I'm really interested to know the function of those two middle pipes towards the tail of the exhaust. It looks like there are open slots at the ends. Does have something to do with resonance for the piping?

I wonder if they'll make this with different tips lol.

They're backpressure tubes. They provide backpressure at low rpms, which aids with low-end torque.

Interesting. I thought they were cutouts that you could un-cap and bypass the second mufflers. Backpressure tubes makes some sense though.

wow. What the hell is that. Stick to the basics haha.

Looks interesting...

back pressure tubes? I would imagine those are more to achieve the right "exhaust note" rather then effect the overall velocity of the exhaust gases.
Correct me if im wrong here, but wouldn't narrowing the piping to increase exhaust velocity be more effective than adding "backpressure" tubes.

No. The whole point of backpressure tubes is that, past a certain exhaust velocity, they're bypassed. In other words, they're variable -- they give you backpressure at low rpm (which is where you want it), but don't restrict flow at higher rpms. If you just narrow the piping, you lose that variability. These tubes are really no different than what HKS did on their exhaust for the 350, so I'm not sure why everyone is so puzzled by these secondary tubes. (Well, maybe people haven't ever seen the HKS 350 exhaust or something.)

sounds mean. i would like to hear it at wot.

Semtex,

Thanks for the pic post as I wonder whether the 5Zigen does not have a similar setup when viewed underneath with the extra cans atop the actual mufflers? Can you please fly your private jet to Japan and find the answer for me? Inquisitive minds want to know. (Now watch AK smoke me on finding this out first.)

Active autowerke uses the HKS style for all of their high end exhausts too.

A side note on HKS. I believe in the most recent Grassroots Motorsports Magazine they tested several exhausts for the 335i and the HKS exhaust was their pick.

I believe those extra canisters on the HKS are for sound reduction and avoidance of drone.

"Backpressure tubes"? Forget what you've heard, but backpressure is a bad thing and kills power. Initialgemini had it right, as exhaust velocity is key. The key is to match pipe diameter to give the greatest exhaust velocity with the least amount of backpressure and of course matching to your power band. A narrow pipe will have greater velocity at low RPMs while a wider pipe will flow better at high RPMs so a well-designed exhaust will take this into account and should have a correct balance.

There's no need for separate piping if all you're looking to do is reduce sound -- that's what in-line resonators are for. Now, I want to be clear here. I am not vouching for the effectiveness of using separate piping for backpressure, I'm just explaining what the intent behind the design is. Personally, I think they're gimmicky. But believe what you want to believe. It doesn't make an ounce of difference to me.

My understanding of fluid dynamics is fairly basic, thanks for explaining.

From the marketing of the HKS hi-power exhaust, these extra canisters are for sound reduction and tuning. In this regard, they are similar to resonators. Search for "dead chambers" for more info on this.

Hmm...well that makes the design even worse, IMO. Extra piping = extra weight. If the right sound can't be achieved with the normal in-line resonators and mufflers, that's just not good. Just my 2 cents.

With regards to the SACLAM unit, it looks to me as though the HUGE resonators up front are what cures the drone, and the extra piping out back prevents the loss of backpressure.

Now, the HKS unit shown above looks like it serves both purposes by incorporating a "dead-end" with a resonator attached to it.

Also, backpressure isn't bad if its used correctly. For N/A applications, you need backpressure to prevent the loss of torque in free flowing exhausts. If you have too much though, then you will lose power. Think of it as a glass of red wine a day. In moderation, its actually good for you, but in excess its not. Horsepower and torque are both important IMO, and not just horsepower.

Hard data is what really would convince one way or the other...............where's the comparitive dyno chart, that and the weight numbers?

I tell you what. If you order it and have it shipped to me, I'll do a dyno. I'll even do two dynos! ;)

I'd like the information up front before ordering.

I'd think the tempatation of this great system would be too much for you to resist anyway?

What youv'e done and published with your car is my benchmark for now :tup:

I have never heard of SACLAM. What is their history/reputation like?

Saclam has a great reputation. Their views on cars are unbiased and rather versatile. They have fabricated products for the S2000, Ferrari, Lotus, Mini, 350Z, and many more.

They basically have their hands in everything.

Saclam assisted ASM in producing some of their products and together they were able to roll out a few unique S2000 products. For those of you who are unaware, ASM is the creater of one of the fastest Unlimited FR NA powered cars in Japan, some say the world.

Here is a website to Saclam's homepage:

Those mysterious tubes? They're Helmholtz resonators. Their length/size orifice is tuned to resonate at a specific frequency which you hope is 180 degrees out of phase (opposite) of the sound you are attempting to attenuate. They can cancel out a specific sound or resonance. Think of it as a narrow band muffler with a high attenuation factor.

The next time you are under the hood of any car, look at the intake tract and you'll see an odd "box" hanging onto the intake tube that goes nowhere. It's also a Helmholtz resonator. If any of you work in an industrial setting, look at the exhaust outlets of your generator, boiler, etc. for an industrial sized version.

Gold Star awarded (rep point). Saclam underwent other iterations of this exhaust as shown in the picture below. To me, Saclam is the Patek Philippe of the available 370Z exhaust systems followed by Amuse.

So uh, SoCal -- you getting one?

I'd love to, buttttttttttt, we unfortunately reside in a private community (never again) and I am a past Board of Directors member so I have to put on a good face (never again). My wife has actually been hinting at one. And yes, at this point in the exhaust game players, I feel Saclam beat them all on sound. The Saclam sounds like it's ready to leave the pits and head to the starting line—intoxicating! :tup:

Wait, this thing is just from the Y-pipe back, isn't it? So they don't even replace the factory y-pipe?

That's correct. They do mention, on one of their blogs, a header system to improve performance that they also show a picture of (a bit hard to see the entire header as it is installed and they are taking the photograph atop the engine bay); the factory Y pipe is most likely replaced in that situation, but with an aftermarket Y.
