New numbers;   (someone please confirm my dia's)
 Earlier ZX-14
 Entire head pipe dia is (1 1/2") {38 mm}
 Exhaust port dia (x2) is (2 1/8") {approx. 54 mm} (2") {approx. 51 mm} {??}
   2006 - 2007 No Catalytic Converter.
   2008 - 2011 has a Catalytic converter.
   

ZX-14R: (2012 to current)
 Head pipe dia "at" the Flange is (1 1/2") {38 mm}
    Head pipe dia @ 2" below the Flange, increases to (1 11/16") {43 mm}
 Exhaust port dia (x2) is (2 1/8") {54 mm}
 No Catalytic converter.   (Converters were in each muffler)

ZG-14 (Concours)
 Entire head pipe dia is (1 3/8") {35 mm}
 (2008-current) Exhaust port dia (x1) is (2 1/8") {54 mm}
 Has Catalytic converter.

Full Area P System {FAPS}
  Head pipe dia at the Flange is (1 1/2") {38 mm}
  Head pipe dia from below the Flange, expands to (1.730" {approx. 1 23/32"}) {44 mm}
 Exhaust port dia (x1) is approx. (2 1/4") {57 mm}
 No Catalytic converter.

Can someone please measure a ZX-14 (2008 - 2011) header Exhaust port dia. ??
I'm not quite certain I have the correct dimension...

Ride safe, Ted

Back in '10 (pre-flash days) I installed '06 zx headers w/ dual Muzzy cf mufflers, removed the secondaries an added a PCV w/Autotune. And yes I 'think' it runs better. Not a dyno within two hours so no it was not done.

Thanks gpink.  I do appreciate the feedback.
Ghostrider sent me a PM and he reports the same as you.
The fact that there was an improvement is good...

I'm looking for a ZX-14 pipe/dyno run so we can see what the pipe actually did.
  With those numbers we can evaluate "where" it got better.

NOTE: Sorry, can't help myself. My background is research, so I need numbers!!

Here are corrected header dimension's.
I bought a set from a 2008 ZX-14 to get this additional info.
Discovered that a 2007-2008 and 2009-2011 ZX-14 header's have different diameters, plus the later models all have a catalytic converter.

As always, if anyone see's an incorrect number, let me know.

I'm referring to the exhaust exit ports at the rear of the collector.
Not sure what else to call them?

The port on the ZG, and the ports on the 2012 ZX-14R are all 2 1/8" OD.

The OD of the ports on my 2007 ZX-14 header are 2". (Which kinda surprised me)
Did a little research and discovered that Delkevic started offering a different exhaust for the ZX-14 in 2008.
So, I think after 2007, the exhaust port size increased to 2 1/8", but I have no way to know that for sure??

If someone has a 2008-2011 ZX-14 exhaust, please let me know that dimension...

Ride safe, Ted

It did change and the only change necessary is a different gasket.

Thanks Thomas. Good info. Matches my findings.
I agree, on the stock ZX mufflers, all that is needed is the correct gasket.
  (I have stock ZX mufflers and gaskets for 2" ports)

That's what started my info search. (I have 2012 ZX-14R headers, and 2010 ZX-14 mufflers)
I couldn't understand why the gaskets were 2' when I thought all ZX-14 headers had 2 1/8" ports.
I eventually bought 2007 headers and discovered the 2" ports.
Was not sure if the later models had gone to 2 1/8".

I've seen posts from others that installed slip-on's and found them too big to fit their ZX headers.
I suspect they were buying 2006/2007 headers, and trying to install slip-on's from a 2008/2011 ZX.
I think buying slip-on's for a 2006/2007 instead of a 2008-2011 will solve the problem?

I'm running a Delkevic C14 slipon on my 07 ZX14 header, I just made a little fiberglass wrap gasket and torqued it down good with an exhaust clamp. No issues with being too loose, it's just as solid as it was on the stock header.

Thanks OKC.
I agree, the gap can be overcome. (I machined an aluminum bushing for mine)
Do you happen to know what model of Delkevics you have?
    I suspect they are for 2008-2011 ZX-14's.

Delkevic Slip-On's (and others) offered different part number headers for 2006-2007, and a 2008-2011 ZX-14's.
   (I think the difference in the 2 models is the size of the Mid Pipe Flare. (Fits the header port)
    If so, 2006-2007 Model Slip-on's will fit best on the early ZX-14 {2006-2007} headers. (with No Cat's)

I used the 9" carbon Delkevic shorty for the 2008-2015+ Concours 14.  No modifications to the midpipe to get it to fit on the 07 ZX14 header.

Thanks OKC. You are correct.
 You helped me find my error.
    I had the Model Years wrong.

Delkevic makes mufflers to fit 2006 - 2007 {w/2" Ports and NO Catalytic Converter}, and 2008 - 2011 {w/2 1/8" Ports and catalytic Converter} ZX-14's..

I should have said;
  Delkevic Slip-On's (and others) offered different part number headers for 2006-2007, and a 2008-2011 ZX-14's.
   (I think the difference in the 2 models is the size of the Mid Pipe Flare. (Fits the header port)

I'm still here; collecting parts to do this project.
Just bought a set of Muzzy's to put on the bike.
Someday, I'll finally get everything collected...

NOTE: I have 2007 header, and Muzzy's that were taken off of a 2008.
          By doing this purchase I confirmed my exhaust port size suspicions;
                    the 2007 header has 2" exhaust ports, and the Muzzy's (from a 2008) are gasketed for a 2 1/8" exhaust port.

Good point!
I'll start with; I like to discuss idea's on the forum....

So, the previous pages were discussion's about;

     the benefits/differences of the ZX-14 and ZX-14R headers.
     asking who has ever done a dyno run with one of these headers. {NONE have done so}
     my idea to block the left side and install a valve {that opens the left side only under certain conditions}
     where to get a valve, what type, and how to install it.
     how to control the valve opening/closing.
     what needs to be on the header to record AFR and pressure.
     what is needed to install the ZX mufflers on a Connie.
     etc, etc, etc,,,,,,,,

But; You'll never know if an idea works, if ya don't give it a try.
           So, I've been gathering parts, machining components, and seeking information.

I settled on a; 2007 ZX-14 Header (without cat)
                     Muzzy slip-on's. (2008 ZX-14)
                     52 mm Stainless steel (flow control/butterfly valve)
                     Stainless steel adapters for the valve.
                     Stainless steel extension for right pipe (to match left side {with valve})
                     Weld in oxygen sensor port.
                     ZX-14 side stand/perch.
                     Steve's Mountain Runner Flash.
                     I'm currently building a muffler hanger for the left side {that matches original/right (ZG) hanger}

My plan is to control the flow valve with springs that allow it to open only at WOT and high rpm's.

Ride safe, Ted

PS: You may ask; Why haven't in installed it yet ..
      Simple answer is; I like to plan/discuss/fabricate more than I like to work..   ;)

Maybe this product exists, but I'm not aware of it if it does.  You know what I want?

A decent 4 into 1 header.  I know a lot of us have slip on exhausts.  My barely used 08 came with the Leo Vince 100% carbon fiber slip on. Carbon end cap. Probably riveted together with sterling silver rivets, installed by topless mermaids....several levels of expense over what I would have spent. The most expensive one in their line up, back then.

So, fast forward to today, and look at the horsepower our guys are getting when they reflash our bikes and install a full exhaust. It appears either the zx14 Akra, or Area p, does a really good job.

I admit I don't need the extra power, but still......

I like the idea of the  Deepsea mod to remove the cat from our stock exhaust, but that still leaves behind small header tubes.

SO, how about a "header only" that would replace out stock header and allow us to run the slip ons we already have?

If you go back thru this discussion you will see that I originally started the project with a (2012) ZX-14R Header.
The ZX-14R Header matches your requirements {almost} exactly.
Bigger head pipes, collectors that match your slip-on, no cat's, bolt on without mods.
   Only problem is, it has 2 exhaust ports. (needs 2 slip-on's)
       I initially planned to run only 1 slip-on, so I built a plug for the left port.
          {I wanted the flow to be smooth across the end of the port, and keep the option to use it if I bought 2 mufflers.
            So I built the plug long enough to match the bottom of the port.
            Others have cut off the left port and welded it smooth}

Later, I decided to use the 2007 ZX-14 header instead. {as I think it matches my (restrictor valve) idea better}
   So, the ZX-14R {w/plug} is available if anyone wants it.     {$50 & ship}
   I also have 2 stock ZX-14 Mufflers. {$100 and ship}
      {If sold; all $$ go to next years "Over the Pond"}


Gary sed; ...but....but....you're retired....
My point exactly!!  I like to plan/discuss/fabricate "more" than I like to work..   ;)

Ride safe, Ted

PS: Gary after reading old posts, I see that I picked the same header/muffler combination that you have.

I'll be getting my bike to Steve for valve adjustments

at that time he can dyno my 2011 with 2006 ? I think ZX14 stock header with cat removed , two brothers cans .

I crushed my left hand in a thanksgiving roll over in my Polaris RZR , skin graft next week , skin missing from top of hand  :-[

Not sure when I'm riding again.

Cuda; I would love to see those numbers!
  (Do you have a flash/etc in the ECU?)

NOTE: If you removed the cat from your header: it is a 2008-2011 and should have 2 1/8" dia. exhaust ports.
          If the header originally did not have a Cat: and the exhaust port is 2" dia., the header came off of a 2006-2007.

Really sorry to hear about your hand...

Ride safe, Ted

I  guess it's a 08 then ,  I'll put it on a trailer and drop it off at Steve's , this should be his slow time.

Not sure witch flash Steve installed , he'll have the bike for a few weeks so he'll have time to play around if he wants.

Not sure when I'll ride again have pins in the fingers now .

Connierider, that zx14 header, using only one side, would match my slip on fairly well? 

And sorry, I'm probably asking what was discussed 6 pages ago,  I thought/wondered if  the diameter of that two outlet (zx14) header might be smaller where it splits into the two sides.

I feel that the alignment/fit will be very close. But, I haven't installed mine yet so I can't say for sure.
One of the other members {I forget who} is currently running only the right port on his ZX-14 headers, and using his (ZG-14) slip-on exhaust on it.            Maybe he'll speak up?

The diameter of the exhaust ports {of all ZX-14 headers after 2007}, are the same diameter (2 1/8") as the single exhaust port on your C-14.       {The 2006 and 2007 have 2" exhaust ports.}

That is 1 reason I opted to use the 2007 headers instead of the 2012.
  (I'm afraid that 2 ea.,  2 1/8" ports may be too much area to assure good low end.)
   (NOTE : The flow of 1 port should be closer match to a ZG-14.
        {but will have more flow because of larger head pipe sizes and no Cat}

I have more than $50 in these headers, and I'll be giving the money to "OtP" so I'm not making any money here.
On Ebay their selling for about $100.
I'm just offering them in case someone wants to give them a try.

Ride safe, Ted

SO, how about a "header only" that would replace out stock header and allow us to run the slip ons we already have?

I agree keep it simple!
