I assume you are referring to the rivets. They can be removed if the outer and inner sections are both brushed and the tip is fully welded. They must be there to facilitate the two-tone customizability of the set.

Anyone have installed pics yet?

Brilliant at stingging everyone along! :bowrofl:

Read through the whole string... what a sucker I am. lol

Sorry about that. I became concerned with the actual demand since they are limited to the HKS exhaust style, so I changed gears and made this universal slip-on exhaust silencer for sport bikes instead.

Bringing this back from the dead. ^^ Did anyone ever get this and install them on a Z? I think they look absolutely epic.

It's not dead...just dormant. :) No sir. Despite the soft inquiries and interest, no one was willing to commit, and I am not able to just get them made without them being pre-paid. Custom orders and all that. :) The designs are waiting to be built. If a couple of you are willing to move on it, we will renew our vendor status here and get them made asap. Of course it is understood that it is a more difficult sale without actual installed pics, but we hope some enthusiasts out there share our vision and are willing to make a move. No risk, no reward.
For what it's worth, the applications that are built thus far look FANTASTIC, in my opinion. You've seen them on the GTRs...and now they are on bikes.

Thanks!

Here is a short "underground" vid from the lab. :)

Fringe XVO Underground 01 Sport Bike Performance Exhaust - YouTube

Completely understood, Fringe.

I personally am looking for an exhaust soon, and I seriously like these tips. Depending on the exhaust I want to get, delivery time will vary from a week, to 2+ months (FI TDX). I'll let you know about looking into a set of those tips, though. It's a seriously unique style of tip that isn't brash or over the top.

Alstann, I just looked at the FI TDX exhaust on the FI website, and the tips that are designed will not bolt on to that unit as they have permanent welded tips.

The tips rendered above were designed to fit the HKS exhaust system.

I won't lie, they look sick on those bikes. :tup:

Oh, I understand that completely. I have my own welding equipment, so it's not an issue to me. I was planning on welding it to any exhaust I decide to get.

Chris, they look awesome right?! I think it would really set any car apart. And I doubt anyone could ever say that it's "ricey" or not clean - the construction looks immaculate.

Honestly, I would love to see a set of these in an integrated rear diffuser. Now this would have to be a custom built rear axle back of an exhaust, but I think it would be cool. Especially for a purely show car.

Fringe, have you talked to any of the exhaust vendors at possibly doing a short run of their systems with your tips, or at least talked about a co-op effort with a limited run group buy? Just to gauge interest?

We haven't. The idea has been entertained though. For several of these exhaust systems they could do it from the "factory", (and that's how we would want our tips put on a welded system...just for accuracy) but we aren't familiar with any of them to the point where we know where there products are actually being made, and based on past experience, we don't trust salesman from "brand x" to be straight with us. We will only deal with people who make their products here. We don't tolerate shops that send products from other manufacturers to other countries for duplication. It's BS and un-American. "Greddy-style" for example. We all know what that means.

We may be at risk of pissing people in the industry off here, but we also believe that the consumer will appreciate the level of honesty that we put into everything we do...and we are sure that we are not the only ones who feel this way. This isn't about money, it's about passion.

If any of you can vouge for specific brands that are honest and real we would seriously consider at least approaching them with the idea. What we will NOT do is allow our product to be de-valued by putting it on a knock-off product.

HKS we trust. What about FI TDX? Others?

I have personally seen, witnessed, and indeed harassed the Owner, Operator, Fabricator, Installer, and all around great guy Tony at Fast Intentions is. His product is 100% made in house in the USA and he is an awesome guy, who has a great shop that makes a beautiful exhaust. And I know I'm not the only satisfied customer here either.

I believe ARK exhausts are also made in the US if I'm not mistaken? They might be open to the idea as well. And theirs is similar in design to the HKS exhaust.

Perhaps Stillen?
And fyi, I do appreciate the level of honesty in your guys' work. You guys make truly innovative products.

I'm really curious to see em on a G37. Anyone with amazing photoshop skills willing to do this? I would jump on these if I knew they looked amazing on a G :tup:

:iagree:

Only have ever heard amazing things about Tony. Haven't had the pleasure of doing buisness with him, but when I am in the market for exhaust... He'll be my go-to guy :tiphat:

We are absolutely willing to collaborate with the right people to design and build whatever is needed to facilitate the installation of our tips onto another well built exhaust system. The renderings previously posted are just that, and they were designed for an HKS system because they were asked for...then no one moved on them.
Understand that any system manufacturer like ARK or FI is going to want to know that if they go through all the work to make this happen that it will pay off. They will have to buy the tips from us, then apply them to their system. If they don't sell, then they are stuck. Our tips are unique and different, and that isn't always good. People think they like different, but then they aren't willing to roll the dice, so they choose a tube. None of us are in the business of losing money, and I know we all know that.
I perceive that the middle ground here might be for someone to pre-pay for their system from one of the aforementioned manufacturers, and then the manufacturer and Fringe collaborate on getting the Afterburner tips installed in place of their usual set. I don't want to put words in anyone's mouth, but it seems logical to me that if a buyer is willing to incur the cost of the exhaust system as well as the tips, then welding the Afterburner tips in place of the normal tips shouldn't incur much (if any) of an additional charge (if they are in fact made in-house). That said, we aren't the one's manufacturing the exhaust systems..so it is what it is.

We will contact FI and ARK and see if they are willing to experiment with at least one system.

Understand that IF they are willing, it will take some time (a week or so) for us to re-design a tip for their specific application...and once it is designed we have about a month lead time before the tips can be assembled, finished, and then sent to the exhaust system manufacturer. I have no idea how long they need to assemble a system and install our tips.

That will be one lucky SOB who gets that system, and one sexy Z/G that gets to wear them. :)

I already pm'd you about those tail pipes and you told me that you will inform me once you have them in production.. and now your saying no1 moved on..

You didnt informed us (well atleast me) that you have them for sale, but lemme know if you still do as im still interested.

Need to see them mounted on an HKS system! I am concerned at how far they will extend from the bumper...

Hmmmm...that could be our mistake, G37HKS, and I sincerely apologize for any miscommunication. By "move" on them, I mean "pull the trigger"...i.e. buy them. I got several responses but everyone that was interested was waiting on the installed pics...and we are not in a position to just get sets made, unfortunately. We completely understand your position as a buyer, so here we are...kinda stuck.

The lengths of the tips were calculated to be the same length as the tubes they are to replace, just like on the GTRs.

If two or three of you are willing to move on this, I will contact AK and get our vendor status renewed, then get these built ASAP. Once they are on the car we could refund $50 for several sweet pics of them installed. If any of you are in the Austin area and have the HKS system, we'd love to work directly with you. Thanks again everyone.

One other thing. The development of the motorcycle version has spurred an update to the GTR design as well, so that it incorporates a cone inside instead of a straight inner tube. I'm going to apply the updates to the HKS Tip Replacements and see if we like it. If so, I'll see what I can do to get them photoshopped onto a z and G as accurately as possible. Pics from some of you with your cars with the HKS exhaust system would be needed.

To give you some idea of the design update, I've included to renderings below. The bottom pic illustrates the original and already produced GTR design side-by-side with the updated version. The new GTR design opens up a little more while retaining all the same outer dimensions, resulting in a lower taper angle. As stated above, it also uses a cone inside.

Send pics to chad.kassem@fringexvo.com or post them to our FB wall. We'll see what we can do with one Z pic and one G pic. Remember, you MUST have the HKS exhaust with HKS tips.

I also want it to be perfectly clear to the forum moderators that we will not accept a penny from anyone here until we have reestablished the proper permissions, and we appreciate them letting us hammer this out. Thanks!

This is a pic of the HKS style replacement tip I had ordered from CNT. It gives you an idea of the length of the tip and what would be visible from where it bolts to the exhaust pipe. The CNT exhaust was too narrow to fit :(

My concern is the tabs would be VERY visible on the design you have come up with....

note how the HKS design slides over and completely hides the exhaust exit by about 2 inches.

This pic shows how the exhaust looks from the rear with the full width opening.

This pic shows the side view and coverage of the stock tip.

I remember these measurements being awkward. The HKS tips slip OVER the 4.5" OD exit tubing of the exhaust, as you point out. From what I can find, there is no such thing as thinwall tubing with an OD of 4.625" that is in the US, which is what those tip tubes are, iirc. The Afterburners are designed to butt up to the 4.5" exhaust exit, with the tabs sliding inside the exhaust section where they will pick up the mounting points.

I was definitely looking at different tips though, as these shown here are a couple of inches shorter, and the Afterburners, while mounting to that, will extend out that difference in length. At a glance, it appears these will extend the entire length of the fins. Let me look at something.
Thanks for the info! This is good data. There is no substitute for getting a hold of a local HKS car, but this may suffice. We have the technology. :)

Here are some updates of the updated design progress.

Send me a pic of the HKS exhaust on a car that is further away from the vehicle, please.

Based on these pics provided by Wheee, a much shorter variant is in order. Hmmm. I'll have to think about it, then get it into CAD for you to see.

This gives you an idea of the side profile and how much the exhaust tip is showing. Your design will have to slip over the stock components in order to hide the plain steel outlet of the HKS exhaust...

An extension (which is what you have basically designed so far) is going to project significantly past the bumper and leave about an 1 1/2" of steel exhaust showing....

http://www.the370z.com/members/wheee...power-tips.jpg

FringeXVO, don't suppose you have an email I can email you with? Sorry if I missed it earlier. I just took delivery of an HKS exhaust system, and I want to look into those replacement tips since those seem to be more viable.

He's working on a new prototype that doesn't extend 4 inches past the bumper! Hope to see a new design soon....

Ah, sweet. I think Sentinel Steel on Pearl White will look pretty swanky. :tup: Especially with an EVO-R diffuser or something. I can just see it now...

Not to mention, I can always switch tips on the HKS system like the Motordyne system.

I apologize for the delays. I am working on several possible solutions. I've had my main compy down and after days of switching power supply, RAM, and re-installing OS and other such nonsense, it turned out to be a freakin' $4.10 cmos battery. FML. I'm about to build a CAD rig with SSDs, RAID 10, and other goodies that will blow this legacy bastard out of the water. I have to go take a calc 3 test in a bit...but I will update in detail as soon as I have some updates.
My email should be on my profile?

I have not yet worked on the shortened HKS version yet, but we are going to be able to jig and replace any tips any of you have with ours at our location soon.

As far as FI or anyone else doing the tip installation, you will likely need to contact them and ask for that service yourself, as the customer.

Please dont leave us HKS owner in middle of sea,
I'll buy your tips in a heart beat as long as the bolt is hidden :tup:

^ agreed. I am not enthused about "shorter" tips as I am more concerned that the replacements will cover the rear area of the exhaust outlet and that the bolt is hidden. I would like it to emulate the HKS slip over style completely as to hide the exhaust outlet....

It won't just be shorter...they can't just be shorter...however the overall EFFECT will be shorter. Part of the design challenge now is designing something that will cover the section the tip will mount to and hide the bolts while allowing for installation using those same bolts. How do you access a bolt you can't see? This is being worked on.
Expect it to take a month or more.

Are your primary concerns the visual of the bolt from the inside or the outside of the tubing you have now?

The Inside bolt is unvisible, Its all black now and no1 can see it, Im concern about the visual of the outside bolt... Please do something about it :)

Thanks.

The HKS tip has a roundhead allen key style bolt that goes thru to a locknut on the inside of the tip. Hardly noticeable and very acceptable. Just use the same design concept on the afterburner tip.
My primary concerns are keeping the approx 4" length of the tip as it slides back and over the exhaust outlet to give depth to the look. The length of the "afterburner" look or taper is secondary. And as a finish, I would love a brushed or polished steel look!

Thanks!!

Here a picture of my HKS system waiting for your tips :)

http://i677.photobucket.com/albums/v...S/IMG_0069.jpg

The challenge with that design is they use a really oddball size of tubing for the tip, and it is not readily available in the US. :/ That won't stop me...it'll just take me another minute. :)

Hence the uniqueness/custom attraction of your tips!

Hope to get the hurdles resolved soon! My HKS exhaust is begging for some XVO tips. :excited:

I've been in my head the last few hours and I got far enough to start throwing it in CAD.

The basic idea seen here is a tip assembly that slides over and butts up to the existing exhaust system, then is bolted in the two locations from the inside via a hidden welded nut (weld nuts not shown yet). The outer section will be supported by the center support ring and 4 welded tabs that will support rivets.

This current model extends and points out past the existing exhaust tube by 2" (The dark grey ring at the edge of the tip is the tip inner ring which butts up to the lighter grey tubing with the oval cutout representing the existing exhaust tubing.)

The tip is .25" thick, ranging from 4.5" OD inner tubing to 5" OD outer tubing.

Can anyone get me the exact measurements of the oval bolt cutout, including its distance from the edge? How far back do the existing tips extend from the oval bolt hole? Out past the tip? Thanks.

Also considering adding a new design concept utilizing a perforated inner tube.
