I just put in a 120r with a Boarzilla pipe about 3000 miles ago. Motor runs and sounds amazing but have got a "band" of discoloration on the heat-shield about 4 inches from the cylinder head. I remember reading a post on this some time ago and someone said they had got this from the band that holds on the shield and sure enough, there is a band right where it is. My questions are 1) will D&D warranty this? (I did not buy from the dealer as a friend of mine that works for a dealership bought it for me direct from the company to get the employee deal from D&D) 2) how do I attach the shield if the band that holds it on does this?
I know the post I read about this had these answers but don't know how to get to that thread.
I appreciate the help!

That is JSwerve that had that issue. I have the same thing going on. Going to tear it off this winter and look into it.
-
I'm on my 3rd heat shield good luck getting it to stop. I have spoken with D&D on several occasions and they say it's the tune. I am calling BS. I have had Fuelmoto working with me my tune is flawless and the bike runs flawless. My AFR is perfect all the way through each RPM range. This is the last D&D pipe I am going to put on any of my bikes.
-
I wrapped the rear pipe and then kind of crowded on the heat shield as that was and is the hot spot guess that is why I have no heat mark on my Zilla. Made it more bearable it was black when I put it on and now is kind of white.
-
If you place some heat wrap just around the pipe where the heatshield attachs to the pipe it pretty much stops it. The heat wrap needs to be the cloth type not the metal type. The cloth will not put as much heat into the clamp and heat shield.

We shouldn't have to wrap anything. If they had it coated like Drago does we wouldn't have an issue. I am going to sell my pipe and buy Franks.

While this is the way I feel as well, the heat wrap does solve it for those not willing or able to afford a new pipe.

This is the CVO forums I think we can all afford a new pipe Steve ;D If you are ok with the quality it really doesn't apply to ya.
I have gone round and round with D&D and I have been a loyal customer and backer since 2010 when I installed a fatcat on my 2009 FLHX. That pipe was excellent, never had any trouble. This model sucks. I have personally seen 4 or 5 other CVO's running the same pipe with the same discoloration at local bike nights. They made a mistake in their process and they haven't been willing to admit and/or correct it. That's not the kind of company I want taking my money. Bummer, I really loved this pipe and the look/sound.

fortunately I am not having the same problem however, I just installed Borazilla's on my glide last week. Picked the bike up on Friday and went for a small ride Saturday A.M., pipes were literally cooking my leg.
took the shields off and wrapped both pipes---(shields do not fit back properly due to the narrow distance between the pipe and shield.) The pipes are very way cooler now which made me inspect my factory pipes and shields, big difference betwen the air gap. I feel that the D&D heat sheilds are too close to the pipe to be advantageous---just my 2 cents worth

That makes sense so let me ask you this, if we can see that, why can't D&D see and acknowledge and then correct it???? I am tired of my right leg feeling literally like it's on fire!

J,
You may not have the discoloration issue with the Drago's 2>1 but the heat under your leg isn't going away with the new pipe if you picked the Dragula as the rear exhaust port bends are just about identical to the the D&D. Just something to consider.....

It would be nice if it was fixed but from what you and other are saying that doesn't sound like it coming anytime soon. My offer on how to stop it from happening comes from having a friend that has the same issue with one. I wrapped just the pipe at the clamp mount points, as a let's try it an see, test and it stopped it for him. It also increased the air gap from the pipe to the shield which may have also helped some. He is happy so I felt I could share it with others in the same boat. Me, myself and I didn't like any of them so I just made my own for my personal bike, so now you know how I fixed it for myself :)

Can you email that fix to D&D? Maybe they will start shipping exhaust wrap with every pipe for a small fee :nixweiss: :huepfenlol2:

It is only happening on the front pipe for whatever thats worth. was tuned by Bob at RC Cycles so I don't believe it can be the tune, Runs fantastic. Did D&D replace the shield for those of you that called them? If they do, I will try the wrap under the clamp. Though it does piss me off that it happened, I love the performance/sound of the pipe and if I had to make a choice, I would still get them. With that said though, I do expect them to stand behind their product and replace that shield. Will see how this goes. I am just stupid enough that if they don't I will buy another shield and try the wrap underneath. I am too old now to "cut of my nose"...
I get that doesn't make it (or me) right...

Wow it's happening on the front pipe too? Lame. :-\

Here's the wrap that I did, the sheilds fit pretty good after some "Country Boy massaging." Way cooler on the motor as well---
-
this picture of the wrap should have posted first---
-
Looks very much like the material I used. I just located the clamp areas for the heat shields and wrapped just those places and used a small piece of tape to hold it in place. Then put the heat shield over it and remove the small tape pieces before tightening the clamps up. Seems to have stopped the discoloration that he was getting. Do not know if it changed the heat on the leg any but he was happy.
-
D&D was very cool about it. They said to send a picture and they would send out a new shield. I already talked to my guy and we are going to do the "wrap" underneath the clamp on the new one. Thanks

Yes they were "cool" about it but did they say they were going to correct the problem? They have sent me 2 shields already that doesn't correct the problem on their end. I guess I am a lot more disappointed with my $1400 purchase then you guys.

When I wrapped mine it was black like above pic. Now it is white :'( and I only wrapped the rear cylinder part of the pipe
-
I believe that all the cloth style wrap is a fiberglass base material, then dyed to give it color. I do not think that the color holds up to the heat as I have seen it change colors, going back to the base color of white as well. Still seems to work the same but the color is gone. The reason I do not wrap the whole pipe is then it acts like a blanket to the pipe. The heat has nowhere to go and it then just get hotter on the pipe itself. So by leaving an open area you give the heat a place to get out and not act like a blanket but more like a heat shield.
One other thing about cloth style wraps is that your pipe underneath the wrap will rot away over time. The cloth holds moisture as it cools off which allows the moisture to sit against the metal until it warms up again. This constant cycle of moisture then heat against the pipes causes the rotting to happen. Some people believe that a SS pipe solves the issue but most of the HD pipes that are made are out of a low grade SS and it really doesn't stop the rotting when wrapped. In the automotive world most if not all header manufactures will void there warranty if the pipes are fully wrapped for this very reason.

Here is a pic (taken in my garage with my phone so not so good) that I sent to D&D
-
Anyone have a suggestion of which wrap I should buy to go under the new clamp?

I thought I would ask 1 more time. New shield should be in next week and I want to get the correct wrap to go underneath to give to the tech installing it for "best chances" of it not happening again.
-
I don't know which wrap is best as I bought mine at an auto parts store. I can't remember the name but it was the same brand as the special ties you put at beginning and the end. Seems like DFI or something like that it was black when I installed it and now almost white.
-
I think most of the cloth type ones are the same other than the color. I've used the 2" wide stuff you pick up at an autoparts store but never paid any attention to the brand name on it.
-
I believe the brand name is DEI, IIRC. Sorry to see you guys having this problem. I have not seen this issue anywhere other than here yet. What about buying a good rattle can of BBQ ceramic paint and shooting the headers? I do this sometimes on 2-1 pipes on the inside of the collector and muffler body before tuning on the dyno (depends on build) to discourage yellowing of the muffler where it slips on to the collector. Works great!

I'm sure there is a fix but my point is after dropping $1400 on the pipe and dummy pipe I shouldn't have to worry about a lack of a quality finish.
-
I agree but as Steve was, I'm just trying to help. Are you wanting help or just posting to rant? Nothing wrong with either and I don't blame you for being upset. I'm just not sure what anybody can do to help you.

This is good wrap from Jegs...

The DEI wrap is good also... JP Cycles sells it here...

DEI, that is what I used. Started out black and now almost white.
-
DEI also makes a ceramic type rattle can of spray paint that is good to make them black again. I have used it on customers bikes who have wanted their faded wrap to be black again. It actually seems to work better as far as staying black than the wrap itself, FWIW.
-
Most all of the colored wrap starts life as white, the natural color of the material. They all fade as they age from what I have seen. A little high heat black paint seems to work as good as anything else for getting the color back for a period of time, if that is what your looking for.
-
My fat cat on my 96 didn't do it, either does the borezilla on my 124. Guess I got lucky. The heat shield does hit the S&S cam plate cover though. I'm kind of wishing I had a quiet exhaust since I've been firing my bike up at 0430 hrs and probably pissing my neighbors off
