C10 Specific Delkevic Installed
« on: May 03, 2014, 12:51:19 am »
I am a cheap dude.  Once these became available though, I couldn't help myself.  The 13" Tri and 14" oval are similar in size to our stock exhaust.  My wife actually got on board and liked the tri so that's what we got.

Came with everything needed including gaskets in both pipes.  Install is straight forward - but there are some qualifiers.  The rubber stops for the kick and center stands do not align perfectly.  Like the pipe is a 1/2 inch too short.   They do their job, but I'm going to call them about it on Monday.  Also, the clamp on that side could not tighten the pipe enough to be rock solid.  Wound up stripping the threads - on there now with the original clamp and several beer can shims.  Hmmmmm.  We'll see what they say about that too.  Doesn't wiggle or leak air or anything, but I can get it to rotate if I use my hands.

Various aggressive raisings of the kick and center stands did NOT cause the pipe to rotate.  But since I can do it with my hands, going to try a new clamp and more shims tomorrow.  We'll see.  It is definitely on there solid though, so I'm riding to the hardware store and probably could forever - but I want more peace of mind, so I'm going to get it better tomorrow.

Quick neighborhood ride then rains so no real thoughts about that yet.  This weekend will tell a lot.  Long ride Sunday.

Sound is great.  Tone is lower, deeper.  With the baffles in it is a little louder than stock, but not much really.  And, with the deeper tone, there is nothing annoying about it.  I bet it will rumble when you get on it, but it is very controllable at neighborhood revs.  Baffles out, it gets even deeper and louder.  I'll have to ride it hard to see, but I don't find that annoying either - probably cause it's deep and not shrill.

Will report more on ride characteristics after some miles.  Will get a better pic up there soon, but figured this would be worthless without at least one.

Thanks for the weite up.  I was just looking at these as an option to replace my flattened cans. Glad you like them, and keep us posted on what they say about the clamp and tabs.

Alekkas, I like the looks of them.
I know of 1 member (Jim Snyder) that is running one of them on a 4 into 1 set up.
He may have a solution to the looseness you mentioned.
Will you be at the National?
I'd like to hear how they sound, and compare with my (modified) Cobra's.

People regularly ask for alternative mufflers for the C-10.
You may have found something that no one was aware of.
Can you tell us approximate cost and where to get them?

Ride safe, Ted

Hey guys.  This showed up on another cogger's thread about a week ago.  He saw them on ebay.  I called the shop immediately and they weren't even on the Webpage yet - just ebay.  Search zg1000 Delkevic. Calling there got them a little cheaper than on ebay.

The tabs are working.  But not 100% contact.  Maybe the last 1/4 inch of rubber bumper gets the front 1/4 inch of the stand's tab.  Everything stayed solid on there today.  Long way to the hardware store was about 20 miles mostly rural each way.  Baffles in there, out on the way home.   Sound is a deeper note than stock.  As expected, baffle in slightly louder, but very easy to control with rpms and load.  Used to be only the intake would growl when jumping on it.  Now I hear the exhaust note too.  Baffles out all around louder.  Still a deep note though. 

Several hundred miles tomorrow - starting with baffles in.  Honestly, I can see leaving them in the vast majority of time for most of my riding because they sound good and have reasonable volume.  Will report back on what they tell me about the left pipe / rubber stops.

Alekkas,
how do they compare to the stock mufflers in terms of weight?   would we be able to shed 10-15 lbs by switching to Delkevic?  what is the material?  is it stainless steel?  titanium?  aluminum?  or plain steel?
thanks,
Brian
P.S.  they look good.

They claim to be in the 4lbs range - I forget - the weight of each one is on each ebay ad.  Not sure how much our stock pipes weigh.  They are light.  Noticeably. 

Stainless.  We will see how they last.  They also sell carbon fiber versions of each pipe for some more $.

So evidently, I had a bonehead install my exhaust. :-[  The gaskets were in the pipes to protect them during shipping.  They were too far in.  While they still served as a gasket for exhaust leaks, it wasn't on the C10's pipe for the clamp to tighten down the splayed edge of the pipe to.  I had no idea.

So, customer service great.  Two new clamps and gaskets being sent for zero $.  I will report back if the pipe still rotates - but I was told that will not be the case.  My bad.  Also, will allow for the left pipe to be better aligned with the rubber stops.  Duh.

Here's a better pic.  Will try to get a vid for sound in the future.  +1 for customer service even when it was my fault.





300 miles on Sunday - baffles in.  Performance was easily as good and felt a little better than with stock pipes, but no dyno evidence to prove it.  Plenty of torque in the twisties.  Exhaust note was great to hear when jumping on the throttle.  But easily controllable at low loads.  Honestly, I was drawn into more revs because the tone was so intoxicating.  Blah blah blah - love em.

Sorry I didn't answer.  I will not be at nationals due to timing.  In July will be up to Arcadia and down to Myrtle for the teens of July.  Up through the dragon in the early 20's of July ON A WEEK DAY!  If any of that works, would love to connect. 

Love those Carbons pictured Dev.  Couldn't swing my lovely significant other that far...

Bob, if it were just me, I'd get the lower priced ovals. But since my wife wanted the tri's I was all in.
 
Edit to add:  Here is a quick you tube video my son shot on my iPhone.  Honestly can't believe I got it posted.  So, only revved to about 4 or 5 K.  Will try to get a fly by up soon.  iPhones vid has lots of crappy high end you don't hear in real life, but I believe the overall tenor of the exhaust tone is fairly accurate. Baffles in.

Here's the vid:

The free gasket / clamp showed up.  Remounted the pipe and it is rock solid.

Could have gotten the stops to line up, but I chose fully sliding the pipe on rather than rubber stop alignment perfection.

Sending them a pic - we'll see what they say.  They'll probably say pull the pipe out a 1/2 inch...

So, solid mounting is not a problem when using the gasket the right way.  Still sound great.

I have been using the Delkevic mufflers on my C-10 for over 5 years now. I have a SS one, a carbon fiber one, and another SS one for a spare. I started bragging on these mufflers several years ago (guess alot of you didn't catch my multiple posts). I even got the C-14 folks to start looking at them and low and behold now they are saying what a great muffler they are. Gee I have only been telling folks this for over 5 years !!!
They are priced 1/3 of what most companies ask for their cans. They look good, they sound great, and the quality is top notch. What else is there not to like. I fany of the newer floks have never seen my 4 into 1 setup with my Delkevic muffler, I will be at the national and would be happy to show it to you. And for anyone interested I can & will show you the trick to modifying the Delkevic baffles to allow for good power and sound, rather than compromising one for the other.

Ted speaks the truth. I have been using these mufflers for over 5 years and have done alot of tweeking with the baffles and brackets.

I agree Jim.  They have been around and done well for a long time according to many reports.  I bet the 4 into 1 is awesome.  I'm just happy they finally made a direct model fit with no tinkering involved. 

On previous bikes i always wound up drilling a hole or two into the slug at the deep end of the baffle.  Might wind up there here too.  Time and putzing will tell.

Actually I use a step drill and open up the round end of the baffle with a 1/2" to 3/4" hole. That releases the excess back pressure which hurts the power, but still keeps the tone tolerable. If you are at the national you will be able to hear my Delkevic on my 4 into 1.

No Sir this is a custom home built system using the Connie headpipes mated to an early 90's ZX-10 midpipe and collectors. If you are at the national next month you will be able to examine it for yourself.

Yes Ted you are correct, I forgot to add the word "Ontario" to my post. Actually its the collectors and the midpipe I referred to is also called the "Y" pipe. So I stand corrected.

Not required, but installing Steve's 2MM jet kit will make the bike come alive. I have been running the 2MM mod jet kit with my 4 into 1 setup and it has killer low end and fantastic throttle response.

What about carb rejetting with these pipes

I have a stock bike set up.  Stock air box not cracked.  Even with the baffles in, the bike is crisper. 

I had the bike for close to 20K miles with two valve adjusts and average like 38, 39 MPG.

Same bike, same rider, same chasing quicker riders WOT through twisties and I'm getting mostly 42 MPG's.  I also did a carb sync within a few hundred miles so that may have something to do with it too.  Bottom line, better MPG, quicker response.

In guitar player terms, we have a phrase that works for me here.  When making a positive change in pick ups or amps or cabinets or speakers, sometimes things come alive.  "Like someone took a blanket off the speaker."   That's what I'm seeing here.
