I replied to your email Patrick, add me to the list. Thanks!

Are there any pics available for option #3? I am looking to connect the rear muffler section of my Invidia Q300 to it

Gernby has an Invidia that he used to test fit. It is very close to the T1R exhaust inlet, you should be able to go with URGE Spec Midpipe only and adjust your exhaust hangers or rubber mounts to fit.

Been waiting for this!

So happy Urge exists.

If you can post up db readings I would be in for sure. Also there was some talk about the hfc not doing well with Forced induction, is that true in any way?

We have been too.. :)

Thank you. Its all about S2000 Passion, all of our profit has been reinvested in R&D and the next product

Ill ping Gernby for db readings. Any specifics on what you are looking for.

One HFC did get loose out of one of Gernby's original 50. We can provide a new cat for $100 and it would cost a few $100 to re weld back in. For less than $300 it can be replaced. Any Forced Induction Car running rich will burn up any cat, OEM, Heavy Metal, etc.

i think any one concerned with the dB reading is going to be using the STR version and a single exit.
A fly by at 75ft at the top of 2nd gear measured at 75ft please :LOL:

We will work on it..

Thanks! On a related note to the STR version,

1. I noticed the STR version of the midpipe does not expand as big as the Urge version. Is this because it does not have sound baffling? Any pros and cons given this design permutation?
2. Do you have dyno numbers of the STR version to compare with stock, test pipe, and Urge version midpipe?
3. Can we get a picture of the STR midpipe side-by-side with the stock midpipe so we can interpret whether the STR rule is fulfilled?

You guys are doing some awesome work here! Tne s2k community definitely appreciates it!

Thanks,
-Michael

Let's see some videos of this in action!

1. Yes it is the reason why we could not fit sound baffling. The reason why it doesn't expand as much is that the cone has to be much longer to meet the STR rules to be with in 6" of the OEM cat. We brought it with in 5". If the STR was the same width it would contact the body.
2. I don have a dyno chart, I can see if Gernby can dig one up. But it does make the same power. Ill see if he can do some back to backs with each pipe. He made a few STRs in his original run and they did make the same power.
3. We can work on that picture as well.

Thank you..

Gernby has plenty of videos from his original run. We will find some links..

The dyno results of this pipe have always been quite impressive.

I do not see a cat in the STR pipe. Where is it?

The STR rules try to define what a "cat" is- is it the pipe containing the cat, the catalytic material, or the expansion chambers containing the cat.

"The extents of an OE converter are defined by the expansion
chamber in which the catalyst is contained, regardless of placement
within larger exhaust sections"

That, to me, would be where the cat pipe tapers into a standard diameter (within 6" of the OEM O2 bung location would be a good rule of thumb). People discussed building a 3' long expansion chamber with the cat at the end but that isn't what the rule intends to allow. The intention is to allow moving the core of the cat downstream no more than 6".

Food for thought.

A quote from the September 2014 fastrack in response to letter #14037:

This clarification pretty explicitly spells out that as long as the expansion chamber begins within (from the rule book) "within 6” (152.4 mm) of the original unit." the catalyst medium can be located anywhere within the assembly.

Thanks for that. They didn't incorporate the clarification into the 2015 rules and I forgot about the FastTrack response from last time this discussion came up. That means a 3' long expansion chamber can move the cat 3' downstream...

is there a hanger welded to the mid pipes anywhere?(I see that there is rubber hanger in the 3rd picture just chilling by itself)

The Cat is on the 2nd part back end of the chamber. The STR and URGE spec share the same back end. Only the front part is different to meet STR rules.
The cat is in the section behind the rear tie bar.

[attachment=82201:Connector Bottom.JPG]


There is no hanger on the Mid Pipe, it is much lighter than the OEM cat and mid section. Gernby never had a hanger on his original 50 units he sold. So we didnt either.

I'm ready for a sound clip of both single and dual!

Any pics of the non-colored Exhaust Tip on the Dual Exhaust option?
Will it just be a 70mm Straight Tip in Stainless Steel? Polished?

I really like the Stainless Steel, Polished Tip option that is available on the Greddy Spectrum Elite Dual Exhaust Polished Tips:
http://www.gotuning.com/images/produ...ished-9030.JPG

Any possibility of offering this type of Exhaust Tip?
Thanks.

We can produce a sound clip of the Dual, but we wont have a Single sound clip until after production as the Single is a new design based off of the Dual.

Our version of the Gern Pipe was designed off the T1R dual, we are simply offering a single muffler based off half the dual for those that have single outlet bumpers and want higher weight. The single will sound like the dual but up to 3 db louder.

The single will simple be the same finish as the muffle, essentially the same color before the gradient tip in the picture. I provided a close up of that natural finish which is polished.

[attachment=82220:Natural Tip Representation.jpg]

Is there any gains to be had between the single and dual or does the midpipe make them equal? ??
Is the sound clup from the dual EM or the dual from the mufflers available to us?

There should be no difference between the Dual or Single. The Dual has less resistance but and the Single has more velocity. Any difference we measure is going to be limited by any weather variances on that day.

As you noted the magic is in the Gern Pipe and the scavenging pulse it creates from 4000-7000 RPM (and another 500 RPM on either side). Anything behind that is for looks or weight.

We were blessed to have T1R work with us to make a complete system. We felt their 70mm was the best no the market from a performance (balancing restriction vs sound deadening), value and quality.

We are working on a sound clip.

Just sent an email, I want in!

Do you guys know how far the tip extends past the ap1 or ap2 rear bumper? Do you have any pictures of the finished product on the s2k by chance? Thank you so much urge, you do so much for the s2k community.

We are using the same T1R Dual Sparrow jig and the tip is the same length away from the muffler, so the current T1R Dual Sparrow is an accurate representation of where we will be.

I appreciate the kind words. We have had some ups and downs but we are trying hard to keep the S2000 evolving and improving.

I wonder if this will be a louder or quieter setup than the t1r-em single 70mm I have now.

I'm hoping it will be quieter than my T1R 70RT I have now also!

For the quietest possible exhaust, I would go with the URGE spec mid pipe that has sound baffling and will reduce drone from 3500 to 7000 RPM. Above 7000, the frequencies will pass through the mid pipe, but if you are above 7000 RPM, you are not trying to be quite. Again we do have sound baffling in the mid pipe and the 2 mufflers to dampen as much as a straight through mufflers can.

Payment sent. Did the first 10 orders go out to manufacturing already or are you gonna make a larger first order?

We are making a larger first order. We Talked to T1R last night and we are putting the order in today.

Videos/db ratings would be great! I really hope this would work on my supercharged car and not ruin the cat!

almost wish there wasnt tip options cuz I am having all sorts of decision making issues!!

Stupid question but does the 1080 include the gern pipe and choice of midpipe?

The Gernpipe is the midpipe.

Yes, See below..

Thank you...

Weight of complete Gernpipe + T1R Single?

How much for a Dual T1R Exhaust with gernpipe?

As we don't have a fully built single in our hands, we are estimating 21-24 lbs. This includes a Cat and replaces the OEM cat section so weight savings can be more than just replacing the exhaust.

We have listed pricing in our first post. We will PM you.

First Buyer in 2nd batch confirmed..

Any word on those video clips? Really want to hear it in action.

which O2 defouler do you recommend?

Piero, still working on it. Timing hasn't been good to gernby and I in the same place to do this.

T1R of course. O2 Simulator

version one or two?

version one or two?
[/quote]

Either should work really, the versions are simply based upon the room available. The 2nd bent version is longer and has less of chance to through a CEL.

If I want a single, is this correct?
$405 exhaust
$1080 pipe
= $1485 plus shipping?

Do we need an O2 defouler even with the High Flow Cat?

The HFC is near the rear axle, so the secondary O2 is well before that. You will need to disable or use simulator.

Patrick

Been lurking around the development threads of these for a while, I've heard the original gernzhaust but would be interested to hear what it sounds like with the tr1 dual setup. Also any reported drone on this setup? Really interested in this, gernpipe gains are impressive.

Me too!

All we have is our 5 year old T1R set up so we are not sure how the sound will differ. We are probably going to record new clips once we get our Spec T1R in. Should be similar but we want clips with new mufflers. If Gernby and I can get a few hours to work together, we will still try to record the current system. Our schedules have not linked up in a while.

As far as Drone reduction, that is due to the Gern Pipe design. Our pipes are copied of their original design and confirmed by Gernby. We will have the exact drone reduction from the previous system in the targeted 3500-7000 RPM range. It is not Drone Free, but should be best in class for that range which is considered cruising for most S2Ks.

We have 10 days left for Launch Buy pricing. We will place an order on August 15th.

Patrick

Any idea what hangers to use? My current single with oem hangers wiggled a little and I noticed over time my bumper melted a bit. Id like to get things squared away before it arrives.

Yup, we have been thinking about this as we only tested the Dual and we wanted to make sure the Single was covered.

For the single, we are using the same 2 hangers as Dual which are on the muffler itself + we paid for an extra custom hanger point. See attached picture.

[attachment=83405:Single Hanger.jpg]

Plus we are including 3 of these with every Single Exhaust (4 with the Duals)

[attachment=83406:Adjustable Exhaust Bushing.jpeg]

AWESOME! thanks :thumbup:

This Launch Buy will close on Aug 15th.

We have 7 orders in the 2nd Batch.

Thank you all for the orders!

last day people

Has there been any progress on a video clip w/ audio?

any updates?

Thanks

T1R has told me the Exhaust should be leaving Japan this month and headed my way on Sea Freight.
The Mid Pipes should be done this month as well and I will get them with in a week one they are done.

The time frame was always going to be based upon the International sea freight shipping.

1st Batch or 20 Exhaust Shipped and 1st Batch of 22 Gern Pipes in manufacturing and shipping soon.

2nd Batch of 12 Exhaust in Process & 2nd Batch of 12 Gern Pipes starting next week.

28 Pre Paid Orders. THANK YOU S2KI.

URGE

Any ETA updates for the first batch of Gernpipes?

The exhausts are somewhere in the pacific ocean.
The Gernpipes are complete and shipping to me this week.

So pumped :banghead:

:whaasup:

Exhaust are running a little late but I have a target date to clear customs on Friday 10/2. We will pick up, test fit a few over the weekend and start shipping the following week.

I have box sizes and weight and will start calculating costs next week and update invoices with shipping.

Any word on the 2nd run from T1R?

2nd batch is wrapping up production any day and will come across the pacific via Sea Freight.

am looking forward to receiving the gern pipe and dual t1r as well :)

the headers is bored just sitting in the room by itself :p

I know this is the original system but damn. If these new versions sound like this I'm gonna have to get in on one of the group buys.

Can't wait to see pics!

Im starting to feel like Christmas is coming

It is, tracking numbers will be emailed by FedEx once the exhaust are in their possession. It will be a 2 piece shipment.

:surprised: :surprised: :surprised:
