I have been looking at the Delkevic 17” Tri-oval from some time.  The sound tone and looks should hopefully be better, but the real reason I wanted it was, I always carry my road tools in the right saddle bag and really want to drop the weight of that potato Launcher to lighten the right side.

Using the previous posts and checking around, I confirmed that calling the office directly is the best way to go.

-The Delkevic 17” Tri-Oval found on eBay was $289.95 with free shipping
-The Delkevic web site had the same item at $286.90 with shipping
-Using the tip to call Janelle in the office gave a discount if you mention COG.  In addition to being cute, she also knows to throw in the rubber bumper, and reassures that the silencer fits.  Total cost shipped was $259.90.

Got my Trioval Stainless a month after I got my Connie. Paid $150 something after a forum member published an Ebay link. Love it and would buy another for sure.

I'd be very eager to shed 24 lbs from this bike, ditch the giant muffler, BUT still keep my neighbors happy with a nice, quiet low exhaust note.

So, I'm thinking about the 18" Carbon Fiber.

Delkevic seems like the way to go, good value and all, but Bruce suggests, "Do yourself a favor and get a heat shield for the mid pipe as that sucker gets mighty hot on yer leg!"

So, anybody know how to do this?   Anybody bothered by the hot pipe?  Bruce, did you do this and could you provide info and/or pics?

I installed the 17" Tri oval carbon fiber yesterday.  I didn't get a chance to ride it yet because of the rain, but as noted by others, it's not louder, just has a deeper throaty tone. It is amazingly light and looks great.

The instructions say to use a high temperature exhaust sealant (supplied). There was no such thing in the box. I had some ultra copper high temp RTV gasket sealant which worked great and is made for headers.

The pipe does come close to the right foot peg, and of course the potato launcher had a heat shield. I figured a heat shield will be a good idea and bought this one. Note the original pipe is 21/4 inches and the Delkevic is 2 inches.

How do you shed 24+ lbs when the stock can with pipe only weighs 20?  I managed to lose 15.5 lbs on the changeover to a CF 18 inch. My new delky exhaust weighs in at a arm busting 4.5lbs.

I didn't use any sealant on mine, I've been doing automotive work for 30 years and that's the first time I've seen using a sealant on an exhaust system. I'll watch mine closely for any leaking and if I see any leaking I'll take it apart and put some in.

With our temps here in Oregon in the high 20's, to mid 30's, I noticed this weekend, when starting up my bike, there was a bit of exhaust steam coming from the seam on the front of my Delk, where it meets the carbon.  Very slight, so I would never had noticed the leak when the temp is warmer.  This probably could account for increased temperatures inside my right side bag.   :103:

If the instructions didn't call for it, I wouldn't have sealed it. This post also made me want to seal the exhaust. At any rate, if it does leak without it, it's not a big deal to add the sealer later.

I did notice after the second day of riding after I pulled in the garage and shut it off I had a little smoke curling out of the pipe, I'm sure this is the internals burning off any manufacturing oil used.

I took mine on a ten mile or so ride and when I got home I could touch the exhaust directly below the case with bare fingers. The temperature was approximately 50 degrees so that could account for the cooler exhaust temp but at this point I'm pleased it's not extremely hot as I only have about 3/4" clearance between my exhaust and case. I'm running without the baffle so I'm assuming I'm exhausting the heat out a little faster than with the baffle in.

Hmm, I went back a re-weighed the stock muffler. I am embarrassed to admit that I got my math wrong, the Delkivic is 14 pounds lighter, not 24.  :-[

Good thing my career isn't math-related, eh?   ::)

14 lbs is still a considerable amount of weight to save on the right side of the MC. To put that into perspective, a gallon of gas weighs about 6.25 lbs, so that is like always riding with 1/2 a tank of gas for the gross wet weight of the MC.  Anything to lighten the ride is good.

I finally went and rode the bike for the first time since I put the Delkivic on. It now has a Guhl re-flashed ECU as well.

The bike is still really quiet, which is exactly what I wanted. As everyone says, it does have a deeper, throatier tone, and sounds cool when the revs climb.

The new ECU did seem to wake the bike up at lower RPM's but it still doesn't have the sheer grunt of an FJR. Once I get out of the urban/suburban setting I rode in (where only brief bursts of acceleration were possible), I'm hoping the difference is more apparent.

Oh, it was the first ride for my new ProjktD wind wings as well. I defiantly noticed a difference with those - my hands stayed a lot warmer with no wind blast on them.

I'm really looking forward to spring, so I can get some miles on my C14!

The 2" shield is definitely the right size.  I'm not convinced it's needed, but it's inexpensive, simple to install and may prevent a burned heal.  The picture shows it at the mid point on the pipe behind and below the peg.  It can be adjusted up or down the pipe, even a bit past the bend points.

I took mine back apart and sealed it with high temp copper Rtv. The installation instructions got the best of me!  :-[

Very nice!

Thanks. It's likely the only piece of chrome I will ever add to the bike. No polishing for me!  I only rode 142 miles with new Delkevic, one trip, and since it was freezing, I have no idea if the shield was needed. Can't hurt I suppose.

Well it only took two years but I am glad the C-14 bunch finally took my suggestion(s) to look at and try the Delkevic mufflers. I have been running a Delkevic can for 4+ years. The price and quality can't be beat.

I noticed that none of you C-14 guys replied to Jims (#7055) Note this time.
As he said, he did suggest the Delkevic's and was told (as a C-10 owner) to butt out.

Ride safe, Ted

A comment like that so long ago, would need to come from a COG number of 9500 or less?  I think everyone is loving the Delkevic at this point. Thanks for showing the way.  :beerchug:

Took the plunge and ordered  the 17" tri-oval. Should be here Thursday.....winter has been brutal here. Can't wait to pull the cover off the C-14 and do something motorcycle related!

I can't seem to find a 17” Tri-Oval Carbon on their website. Is that me or don't they sell it anymore?
Would the 13" be much louder? Would be for the 2014 model year.

I have the 13" tri-oval and it is not loud. I can't compare it to the 17", I haven't seen one.

I am very happy with it, at idle it sounds great, throatier not louder and it barks when you accelerate hard.

Has anyone heard of or tried his brand of exhaust? I want to shed the weight of the stock exhaust but don't want to be too loud! ? ???
Just to be different I went for the round one. Works great and not that loud with the baffle out. You must buy a stainless cap screw for the hole that is left otherwise you get vibration and a hissing sound!

reviving an old thread, still the best deal out there.  If it only makes it a little louder so someone can hear me coming im fine with it.  Dont care about the performance so much as my second thing is the weight savings.  I went with the stainless round, cheapest so made sense.  Cant wait to see how it does

Hey 4Bikes....I'm curious just how much room you have between the brake pivot arm and the pipe. I have an AST peg lowering kit on my bike and it lowered that pivot point 1 3/8" which works fine with a stock pipe. Do you think there is 1 3/8" between your pipe and that pivot point on your Delkevic ?
In theory, practice and theory are the same. In practice, they aren't. Without data you are just another guy with an opinion.
