Hey Fringe,

I don't have access to my car at the moment, but I thought I could help with measuring the Ti tips for you.

I took some quick measurements from the mounting hole on the tip to the backside of the tip, so you can get an idea of length. Measurements are in MM.

Here is how the tip sits on the exhaust. Excuse my crude MS Paint skills, this is a very basic idea. But you can see how the exhaust tip extends past the steel inner exhaust, and also extends outward toward the rear of the car. Also, of course, the inner steel mounting piece has an oval mounting hole, so you can adjust the length. Pretty simple.

Here is a picture from the edge of the mounting hole to the edge of the backside of the tip (Not from the center of the mounting hole)

Here is another picture, where I tried to measure from the center of the mounting hole to the backside of the tip.

And here's a somewhat close measurement of the mounting hole to the EXIT of the exhaust tip. Don't forget that the tips are slant cut.

I hope that helps some. When I get my car back, I can do some more caliper measurements of the actual tail section of the exhaust for you.

EDIT: I also wanna note that from the side of the car, you could see the backside of the tips, showing that they were not a uniform piece of the exhaust. Not saying that it was a bad look, in fact, I loved the side profile, just a note I remembered.

I think an XVO Afterburner tip that was around the same length or somewhere close to the stock HKS tips would be good. Any other opinions on that?

Any new CADs on this Fringe?

Alstann, how big is the bolt hole?

my rough image calculations from the photo put it at 8mm diameter

Okay.

Two final things:

1. Does anyone know what size metric wrench fits the nut? From that I can tell what the actual bolt size is. If no one knows for sure, it's no biggie. I will use a grade 8 equivalent M8 and that will suffice for the app.

2. I need to know the distance the oval that the bolt goes through is from the outer edge of the exhaust system.


The design rendered above is it...save for adjusting the bolt hole size and making sure that the bolts are positioned so the tip can be snugged up to the exhaust system. None of the adjustments I need to make will affect the look of the tip.

So I posted them a while ago and no one responded, other than to ask when they would be finished...so I'm not sure what's wrong. The conditions everyone set have been met. The tips slide over and conceal the whole exhaust section just like the original tubes do, and these variants completely conceal the attaching bolts from the outside.

What's wrong? What did I miss?

Thanks! Working with actual forum members to develop something they want isn't usually done, and I really hope this turns into a success story.

Okay. This image here has potential. The metal extending past the main body at the rear would have to go. The actual exhaust pipe exits at an angle and is much narrower. The tip actually conceals the hemispherical exhaust end that angles away back toward the resonator.

The back of the tip extends past the hemispherical exhaust by a small amount and looks like it 'floats' on the exhaust end.

Fringe, I really appreciate what you're trying to do for us. The problem is you REALLY need a donor car to see exactly what you are working with. There has to be someone in Texas that can drop by and let you get all the measurements you need.

I would make the drive myself if I could get the army to give me leave long enough! lol

:icon17:

Sorry for not explaining better. That inner tube extending out of the rear in that rendering is simulating the exhaust itself. I should have, but didn't draw it necking down and going toward the resonator like it actually does. The renderings down below that one don't show that tube at all.

This is just tips not like a axle back exhaust??

Just tips.

Fringe,

Sorry for not seeing this response earlier! I am at work at the moment, but after I get home, I will remove one of my exhaust tips and make some measurements. I'll also measure the Exhaust Tip Bolt Hole diameter exactly for you.

As per your first question, the nut for the tips are a 10mm wrench nut, and the bolt itself is a smooth rounded ----
**EDIT** It isn't a T-20 Torx bolt - turns out I lost the right sized torx wrench. I'm unsure what it is, but it probably doesnt matter in this application.

I really hope this becomes a reality! I can't wait to get the measurements, haha.

Alrighty, as I promised, here are the pictures.

Here is the driver's side exhaust section, without the Ti tip:

http://i248.photobucket.com/albums/g...702_232923.jpg

I measured the internal long-ways diameter of the oval on the exhaust section:

http://i248.photobucket.com/albums/g...702_233018.jpg

As well as the distance from the end of the oval to the end of the exhaust (7.74mm):

http://i248.photobucket.com/albums/g...702_233120.jpg

This is a somewhat rough measurement of the entire length of the larger diameter exhaust section, before it necks down:

Inner diameter of the Ti tip mounting hole:

And last but not least, total length of the stainless steel bolt:

If you need any more measurements, let me know. I repeated each measurement a few times to make sure I didn't get it wrong, and each result was within .05 of the pictured measurements.

Awesome pics and info Alstann! Now drive to Texas and get your car on Fringe's test bench! lol

sub'd, these look sick

Thank you Alstann. Can you do one more thing? Will you verify that the tube with the slots in in fact 4.5" OD tubing? I believe the system I took my preliminary measurements from was an HKS copy, and I want to verify that these tips will fit your HKS setup. Don't want to get screwed by some silly inconsistency.
Other than that, I will make the adjustments and prepare the drawing for quoting. I should have prices in less than 2 weeks. I wil renew our vendor status here and once the required number of pre-orders are filled, it will take about a month to start shipping tips.

It's almost time for the hardest part...picking the colors. :)


Below are some renderings of the new perforated tip that is going on my bike and being adapted to the GTRs. Is this something some of you might dig? Obviously the "Afterburner" isn't for everyone...so we have a few other designs in the pipeline. Let me know you thoughts.

No problem Fringe! Here are the requested pics of the exhaust end of the HKS exhaust.

Here is the section that I measured...

http://i248.photobucket.com/albums/g...703_132725.jpg

And this was the reading.

http://i248.photobucket.com/albums/g...703_132720.jpg

It is indeed 4.5 inch OD piping.

Mmm, colors. I don't know if I could decide between a brushed, reflective tip or a more satin finish tip. :icon17:

My vote would be a satin finish like the hyper silver wheels and trim....

Alright! Thank you all, this is epic and I think the first time something like this has been done... usually people make something and just try to sell you on how awesome it is, then tell you that you have to buy it however they give it to you.

We do it a little different. We allow you to make it YOURS. We aren't afraid to ask for input or just generally be straight with people. Fabrication and manufacturing can be a strange world. Generally we see salesmen that need something to sell so they can chase dollars...and fabricators tend to build things because they enjoy building things. What I've seen this lead to on multiple occasions is salesmen (or anyone else with some money) readily take advantage of a fabricators love of creation and just swoop in and claim ownership of whatever is being created, since they feel that without them there wouldn't be any sales. Fact is, without the creators creating, there would be nothing to sell and no reason to have "salesman".

Fringe XVO is taking it back.

We are not salesman. Well maybe Carl is a little bit, but he is multi-purpose. I give you my word, Fringe will NEVER BE RUN BY SALESMAN. Granted, we have to generate sales, right? The point I'm trying to make here is that we aren't out to SELL you on anything. We are just here to be awesome. We are just here to do cool and fun stuff, because it's fun and awesome to do that...and we want you to want it. We like things that look good. We like things that look good AND function. Sometimes the function is just to look good. Sometimes the function is to make power. Either way, everything is function. People often don't get it. Sometimes just looking good IS THE FUNCTION, and some things just function better than others.

If I type "function" again I'm gonna shoot myself, but the point is this:
We are not here to get rich. We are not here to be "ballers".

We simply exist to do great things. Either you get it or you don't.

Happy 4th.

Everybody get funding! I'll drive if ya'll pitch in. :happydance:

As for the tip design, I know it might be late in the game now, but I just had a thought this morning - fellow owners of HKS exhausts will know this. From the side of the car, you can see where the Ti tip "stops," as in the backside of the tip, near the muffler cans. If there was a way to have an elongated side on the FringeXVO tips, it would give the illusion from the side of the car that the tip is contininous.

Just food for thought. Either way, I can't wait to see production pictures!

hmmmm... not sure about that.... If they are not symetrical, then they might look poser'ish. I think leaving them the same length as the stock HKS tips is best. I don't mind the 'sleeved' look.

We could make them a little longer than the HKS slip-on tubes. How much room do we have before the tip would contact the exhaust muffler?

Not enough for people that recess them to look more stealthy. If you extend them fully out along the adjustment slot, then it is more noticeable.

Understood. I will not lengthen them. Final renderings will be up by Monday, I hope.

I will prepare the drawings and send them off for quoting. Once I get the quotes back, I can let you know how much they will be for a set.

If you guys like them and you can get 4 or 5 pre-sales together, then we'll move on them. :)

Thanks again to ALL of you the have contributed.

-Chad

You are very correct - I completely forgot I moved my tips out somewhat further than the stock tip position. Nevermind what I said!

Sign me up for the first set!

1. Alstann

Done. Who's next?

1. Alstann
2. ?
3. ?
4. ?
5. ?

So these will only work with the HKS system? I may end up purchasing these and attaching them onto a custom axle back instead of buying an HKS system. hmm..

Hey Fringe,

I think you might get more traffic if you crosspost this into the Exhaust/Intake thread. Maybe once you get your final design pictures? :happydance:

pending price and final design/finish...

Price is expected to be around $100 each, so ballpark $200 for a set. That may include coating, def won't include shipping.

Finishes are whatever you want it to be. You can see some examples of different colors on the fringexvo website and on our facebook page.

I should have some final renderings and at least one short video of the install up later today. :)

Super quick assembly video here:

Fringe XVO Afterburner HKS slip-on tip install video.avi - YouTube

Looks good! I like the hyper silver finish. Is there an way to eliminate the rivets and maybe weld the inner sleeve to the outer sleeve? Or maybe the rivets would not be necessary seeing as how the slip on end would be bolted onto the HKS exhaust... that would make the inner sleeve removeable. Maybe allow for different colour inserts even... just a thought.

I agree, it looks sexy! :driving:

I saw on the website that custom colors can be done for the R35 tips - I wonder what kind of color combination would go well. To be honest, I would be so happy with these hyper silver tips with a black inside.

The rivets are necessary. The outer section could be welded to the inner, but that forces everything to be plain stainless. The only way we can make these tips available in two tone color is to use a two piece design that allows for each colored section to be powdercoated separately, then fixed together using a method that will not destroy the coating...hence the rivets. Due to the electro-magnetic properties of the powdercoating process, simply powdering a finished tip limits us to a certain few powders like all flat black, which tends to hide the detail and precision that goes into each of the tips. Not a single customer has ended up getting them in all flat black for that very reason. Most powders will not go through the small gap between each fin because of the magnetism.

The silver outer and black inner is the "Sentinel Steel" variant. If you haven't seen the "Phantom Black" sets for the r35 then you are missing out, cause they are subtle yet sexy, and one of my personal favorites. "Phantom Black" is flat black outer with a high gloss black inner.

As far as other combinations go, well, the world is your oyster. I'm still waiting for someone to do something flashy, like color match the calipers with the inner section. Eventually the inner part of the inner section will be carbon black from the exhaust, leaving only the tubing visible through the fin gaps to show the accent color that matches the calipers. I think that could look totally bad ***. Most people just tend to ask me what they should get though. I give people choices, and they just give it back to me, lol.

I will be sending these off to get quoted in the next couple of days and then I will have hard price numbers. Give me a week or two.

Looking forward to it! Great work and thank you for your efforts!

I'd love to see some high res photographs of the finished, powercoated tips in both Sentinel Steel and the Phantom Black. I'm trying to decide a color for my Pearl White Z! Such a hard decision, haha. Maybe even a crazy color combo, such like a white outer with a black inner section. Mmm.

Looking forward to the hard pricing. Maybe a discount for the first few peeps? :bowrofl:

Like wheee said, thanks so much for coming through and making the tips. I'm glad I could help you out with the measurements, I can't wait to have a truly unique-looking rear end!

Thank you for your patience gentlemen (and women?). I have poured over the designs, literally quadruple checking each calculation. I apologize for the time involved, but I have to make sure things are perfect the first time.

I have sent off the designs for component quoting and should have the hard pricing in a couple forms by Friday.

In the meantime, here's a little more eye candy. :) (Note: I've decided to change the mounting hardware from the button type socket head cap screw that is shown to a short fine-thread stud with the appropriate nut and lock washer.)

Looks good Fringe! Let's get these mounted! :yum:

In for epic.


:happydance: :driving: :excited:

So excited to see this coming to reality!

Epic isn't cheap.

So here's the part we all wanted to see but don't really want to see. With these prices, I'm not even barely making anything...but not every project is about the money. If you guys are willing to organize and move forward, then I'll do the work. Here are the hard numbers.

2 sets @ $700 each
4 sets @ $400 each
8 sets @ $320 each
12 sets @ $250 each

Notice the power of the group buy here. Just getting the 2 sets made for Alstann and Wheee is just plain ridiculous...in fact I don't even consider it slightly reasonable until we get into the 12+ range. My problem is I can't justify the capital it would take for me to spend in order to put 12 sets of tips on the shelf when no more than two people have really shown serious commitment.

So now that this just got real...who's in?

I triple-dog-dare Alstann, Wheee!, and 10 more of you HKS owners. :)
I've done my part and I've done it for free. Where is everyone else? :)

1) wheee!
2)
3)
4)
5)
6)
7)
8)
9)
10)
11)
12)

Fringe, if you don't mind, I am gonna look into crossposting this into the main Intake/Exhaust forum, as well as posting it into G37 forums, and possibly 350z forums. Are 350z HKS exhausts the same type of rear section? Tip diameter wise and whatnot? At least g37 guys can use it, that's for sure.

I would die if I ever tried paying $700 for tips, haha. :ughdance:
