Delkevic full exhaust
« on: August 04, 2019, 11:02:32 am »
I received my Delkevic header & 14" stainless slip on.
Here is a little more info I hope you all find a bit helpful.

Weights are as follows: 2009 C14
Stock header- 11lbs. 10oz.
Stock muffler & pipe - 19lbs. 10 oz.
Total 31lbs. 4 oz.

Delkevic Header 8lbs. 10oz.
14" Stainless muffler & pipe. 6lbs, 6 oz.
Total 15lbs.
Delkevic header primary tubes. I.D.   34.4mm / 1.35"
Delkevic header primary tubes. O.D. 41.6mm - 1.64"

I did not measure the primary tube diameter of the stock header. I'm sure that info is out there somewhere.
Overall I feel the Delkevic is a good quality header, it looks great but I did not like the transition of the primary tubes into the collector.
There is quite a lip inside the collector.
I'm revising it for better flow. Also taking out the 02 sensor bungs, don't need them on my '09.

If you keep the Sensor Bung, you could probably use it for dyno pulls / wide band. {?}
   Your Delkevic is very similar to a ZX-14R header.
   I think you'll find; the first 2" of the Primary Tubes are smaller than 41.6mm - 1.64" O.D. and Cyl's 1/2 and 3/4 are paired. {??}

Here are some dimensions I worked out..
 
ZX-14 2006 - 2007
 Entire head pipe dia is (1 1/2") {38 mm}
 Exhaust port dia (x2) is (2") {approx. 51 mm}
 Has no Catalytic converter.
Cyl's 1/4 and 2/3 are paired.


ZX-14 2008 - 2011
 Entire head pipe dia is (1 1/2") {38 mm}
 Exhaust port dia (x2) is (2 1/8") {approx. 54 mm}
 Has Catalytic converter.
Cyl's 1/4 and 2/3 are paired.   

ZX-14R: (2013 to current)
 Head pipe dia at the Flange is (1 1/2") {38 mm}
 Head pipe dia from 2" below the Flange, flares to (1 11/16") {43 mm}
 Exhaust port dia (x2) is (2 1/8") {54 mm}
 No Catalytic converter.

Cyl's 1/2 and 3/4 are paired.

ZG-14 (Concours)
 Entire head pipe dia is (1 3/8") {35 mm}
 Exhaust port dia (x1) is (2 1/8") {54 mm}
 Has Catalytic converter.
Cyl's 1/4 and 2/3 are paired.

Full Area P System
  Head pipe dia at the Flange is (1 1/2") {38 mm}
  Head pipe dia from 2" below the Flange, flares to {approx. 1 23/32"}) {44 mm}
 Exhaust port dia (x1) is approx. (2 1/4") {57 mm}
 No Catalytic converter.
{I think} Cyl's 1/4 and 2/3 are paired.

Ride safe, Ted

If you keep the Sensor Bung, you could probably use it for dyno pulls / wide band.

Could also increase value if resold later for any reason.  I can't imagine removing them would have any great advantage.

Thanks connie_rider

No pairing on the primary tubes.
Would you recommend keeping the collector bung?

Assuming they are not interfering with anything I would leave the 3 bungs on, as they aren't hurting anything, might be useful for tuning, and if you choose to sell they would be in place for someone with a newer model.

When I referred to pairing: I think there is a short Y pipe for cyl's 1/2, and another for cyl's 3/4. They are just prior to the collector?    Hard to see in this image.

Found an image of a used stocker on Ebay. You can see the 2 Y's and the change in Primary Tube diameters more distinctly in a stock ZX-14R header.

No crossover tubes for sure.
I'll look again to see how the collectors merge.
I didn't like the possibility of diisruption of flow of the bung if I didn't need it.

On the OEM ZX-14R headers, the metal tube's between cyls 1/2 and 3/4 are brace's and do not have crossflow.
ie; Each brace has a hole drilled in the bottom and are not open to the head pipes.

If you have the capability to weld SS it will be simple to remove the Bung tubes.

Dimension explanation; When I installed my headers, I bought headers from a 2006 ZX-14 and a 2012 ZX-14R so that I could compare.
I opted to use the 2006 headers as they had 1/4 and 2/3 pairing like a Concours and head pipe dia that is a closer match to the ones on a C-14.  The bike runs very well now and I'm happy with the set up. 
NOTE: I have Steve's MRP flash in my ECU.

Now that Delkevic is offering these {which are basically ZX-14R copies} it makes me wonder if I made the right choice.  :banghead:
So, I'm watching to see what folks think about the Delkevic set up and how successful Steve is as he develops a Flash for them..
  {shhhh, Don't tell my wife}

Ride safe, Ted

Bungs cut out & patched, lip on the collector ground out.
I'm excited to put it on. Too busy this weekend so it looks like next week before it's done.
Next up the tune...stay tuned.

If you get a chance, can you post some photo's of the mods you made?
Anxious to hear how the bike runs after the install.
Do you intend to install a Flash/other, and {if yes} when?

Ride safe, Ted

Here are the before and after pics. The lip is now ground out for better flow.
If you have one of these you'll see what I mean.

Thank you.
I can see where your grind would improve flow.

Thanks Ted

Yes, it should by a fair amount.
I'll compare & post heat and noise data with my Son's stock header with cat & Delkovec 14" stainless.
