So glad your back together & back to making videos that always worked.
Now it's exciting again❗
Don't change something that ain't broke.
Keep Living the F#@KING Dream ❗
Safe travels 🙏♥️🐾🐾
💪🇦🇺💪
Glad you are digging the videos.
We still have a few more Hoodie videos left. Those will be coming out over the next 4-5 weeks. Dwayne and I have also recorded 6 new videos in the last week that will be coming out over the next 4-5 weeks also.
Thanks for the good words, and enjoy your summer!
DK, you guys hit the nail on the Head. 👍
Thanks man, appreciate that! 👍😎👍
Another great video!
I’ve always used a minimum of one times bolt diameter for thread engagement.
Thanks for sharing, we do the same. Great tip! We should mention that more, but that is a very solid rule that we follow also. 👍
just installed the TTI-158 in my 3.5" free flowing reinhardt slip ons with open baffles and for my application the reversion is all but gone , 2009 Triglide with woods tw555 cams and S&S tc3 cam plate and oil pump and woods directional lifters and fuel moto adjustable pushrods and base tune map and K&N big oval complete Air cleaner intake system 😀 thanks guys for the help with my Ole girl 🤪
Thank you for the comment, and we appreciate your business. 👍
Always good to hear how our parts are helping Harley's run better/stronger.
Wishing you a lot more miles of smiles on your TG!
As always I appreciate your videos and products. I would recommend that you spend time discussing with your staff what size TTI to recommend to customers based on the baffle size, the cases where the TTI will be installed in the baffle. For example, 4" pipes with baffles attached to the tips do not take 258's. A conversation about what questions to ask the customer to determine correct sizes would save time and money. Thanks again!
Good to hear you're liking the videos and our parts. We appreciate your business.
Thank you for the suggestion.👍
If your baffle is, say 2" in diameter, then a LT 158 would work in the tip, right behind the baffle.
A 258 would also work in that 4" diameter tip.
A 158 mounted in the actual baffle end would also work.
All those set ups will work to deliver about the same amount of increase in torque. They would also each sound a bit different.
By DK Custom Products accommodating the few,they will attract more of the H-D and other masses.I can see this small company giving other like businesses a run for their money.The best thing about it is,more competition leads to lower over all cost. WIN WIN.
Thank you for the kind words. Much appreciated.
👍
Nice quality design , beats the hell out of what we used in past years, an eyebolt and welded washer
You got that right!
Thanks for the comment Jack, always good to hear from you. 👍
I bought a set of 158’s. No wafering on the wave interrupter. Did not use them. Reminded of when we use to weld washers to a bolt.
Lost you on the wafering on the wave interrupter.
But yes, these are highly refined lollipops.

Glad you're digging the vids! 👍😎👍
This is great,we did start this back in Shovelhead,EVO days.Back then the first Dynos arrived.Just a washer about 1Inch in dragpipes. It vill work to pick up low end performance in any Harley. If you put out a Dynograph before and after people will understand. Sorry to say , now days new dogs dont always understand,,God work guys
Yes, these are an evolution of the bolt and washer that so many of us used for decades. Before and after dyno charts can be seen at this link- www.dkcustomproducts.com/thunder-torque-inserts-158-model-family-dk-tti-158.htm
And a video with dyno charts can be seen at this link- th-cam.com/video/b2mN7lZ1CLw/w-d-xo.html
What size would you recommend for the Hard Krome 3" Big Straights, I'm guessing they would need to be installed at the tip mounting point as the baffle insert mount is a bit hard to access inside the exhaust.
Excellent video by the way, keep up the great work.
Glad you're liking the vids!
Here is a video showing how to install- th-cam.com/video/FbsPDZNi5Zw/w-d-xo.html
Here's a link to a chart to show what size to get, based on the size of the hole where you are going to mount them. www.dkcustomproducts.com/choosing-the-right-size-thunder-torque-inserts.htm
Your 3" Big Straights may not have a 3" Inner diameter due to a baffle or an end cap, so use the chart above as guidance.
Thanks for all the info, fella's! I'm looking to install something that will give me some more low end grunt. Running S&S 585 cams on my TC110 Dyna and while the cam is great, doesn't really come on until 3k rpm and up. I'm running Rinehart Crossbacks which I think are 2". Reckon the TTi 158's are the way to go? Cheers!
Yes, you should get a 5-10% increase in the low to mid range RPM with the 158 TTI's in your Rineharts.
Here is link to a fitment chart to use when you double check the size of your baffles- www.dkcustomproducts.com/choosing-the-right-size-thunder-torque-inserts.htm
I keep seeing you say back pressure isn’t good or necessary on a Harley yet your torque inserts definite, absolutely increase torque!
And back pressure
That is because backpressure is bad for power. Backpressure is a power robber. It, literally, makes the engine work just to get the exhaust out.
Additionally, backpressure prevents a full combustion chamber fill in the intake stroke.
Here is a video by master engine builder Gale Banks on the subject that you may find helpful - th-cam.com/video/mZ53YO_RZ0E/w-d-xo.html
The Thunder Torque Inserts utilize a patented design that works 200% - 500% better than lollipops or cones. The unique shape Speeds up Exhaust Gas Velocity, in addition to reducing/eliminating reversion.
Two major keys to power.

Frick guys, I just installed the large one that you sell in big Vance and Hines Could have really used this longer stud insert.
Yeah, that is the catch-22 of always working on improving things.
As long as you have your 258's close to the center, you are good.
Thank you for your business, we appreciate it. 👍
I put Rhinehart 4 in slip ons with the DBX baffle on my 22 TriGlide. Would I benefit from these installed and which one would I need. Will it go inside the baffle.?😎😎
Yes, you will see a performance increase in low to mid range torque having the TTI's installed. I would need to know the inside diameter of your baffle to tell you what size TTI you would need.
You can email us a picture looking into your exhaust with the inside diameter measurement 1-2 inches in and we will tell you what size you need;

Have a question not related to this video at all, do they make a kick start kit for fuel injected bikes? Really nice to have both options lol. I think kick start always looked way cooler and bad ass.
I have seen kickstarters for the late model Sportys. If you do a google search for "2007 sportster kick start" you will see quite a few different conversion kits. We have no experience with these, so cannot say how well they work, or hold up, etc.
I thought about doing it quite a few years back to one of my Sportsters, but never pulled the trigger on it.
It would be cool though.
If you install these, do you have to re-dyno tune your bike? I have Tab 4.5" and started out with Zombie baffles and had it dyno tuned but after a year of riding it was just too loud so I pulled the zombies out and installed the 2.5" baffles (medium) and had it re-dyno tuned. It lost 7HP and 5TQ but now the sound isn't unbearable and pretty good. I was just wondering what size you'd recommend for the Tabs and if I would need to retune the bike (the speed shop charges a couple hundred bucks since it's a trike.
No, you will not need to re-dyno tune your bike to install and feel the effects of the Thunder Torque Inserts.
Is the inside diameter of your baffle 2.5" ? I will need to know that to help you choose the correct size.

Been told true duals such as V&H Dresser duals will lose power on low and mid range torque.
I've been listening to alot of video sound bites of exhaust tones, I find CFR mufflers really hit home for me. At least from video sound I feel they have the low tone deep rumble I'm looking for.
So now I'm sitting with 2 items in my cart, items that I am told will lose torque and hp low to mid range.
My questions are;
1. Have you ever installed TTI on a set of CFR mufflers? Can the baffle come out and bolt to that vs drilling through the exterior pipe?
2. My bike is stock, FLTRXS 103HO, I purchased your 828 AC with transformer, external breather with catch can.
With the AC, dresser duals and CFR mufflers & TTI (if they can be installed in CFR's) am I going to lose low & mid range torque below stock performance or am I not going to gain as much from this stage 1 vs a stage 1 if I used different components?
I am not a hot rod rider, just started riding my wife on the back and we plan to go on some weekend type trips. The power the bike has in stock form seems to be fine as it is although we have not been on an interstate trying to pass cars yet, so not sure how she would perform at that. I have put about 30k miles on the bike riding solo usually cruising under 3k rpm, shifting right around 3k. With the wife on the back I've been trying to adjust my riding style to cruise around 3-3.5k and shift 3.5-4 k rpm. Seems to have a little more response up there.l
3. Do you by chance have any Dyno logs of a 103HO, dresser duals, CFR's, stage 1 AC? Would love to see what I am looking before stepping into it.
Thanks for the videos, great information. I'm learning so much about my bike that I had no clue. Really appreciate it.
Take care.
If you do have a Dyno logs, I can email you about it.
Thanks again
We have not personally worked with CFR slip-ons, but we have had quite a few Customers that have and are happy with the low & midrange Torque gains.
All the CFR's we've seen have just a mesh holding packing in-between the mesh and the wall of the slip-on. That mesh is welded in, so not really removeable. The TTI's on CFR's get mounted in the End Caps.
With the 828 and Transformer, you are going to gain torque & hp across the RPM range, regardless of the exhaust you use. However, you will gain even more with the TTI's in your dresser duals/CFR combo.
To be clear, with the dresser duals/CFR combo, along with the 828 & Transformer, you will have more low and mid range torque than with the stock set up.
Another thing to note, regardless of the exhaust, you will need to use a Power Vision, FP4 or ViED's for your tune. All Twin Cams, since 2007, run too lean from the factory.
That is a good change you did with your RPM's. Twin Cam's generally produce the most torque between 3000 and 3500 RPM.
We have never had a bike with CFR's on the dyno, so no charts from us on that.
Last thing to note, the following video link is the only way we know to choose the "right" slip-on the first time (unless we got lucky). I think you will find this video useful- th-cam.com/video/H681dl2X_f4/w-d-xo.html
what if I put it just before right muffler on a decat stock rg exhaust headers running 4 5 in VH.. Idea to get more flow out the left muffler
Reversion, which robs power, occurs at the tail end of the exhaust, where it hits the outside atmosphere. The TTI's are designed to reduce/eliminate reversion by being place near the end of the exit end of the mufflers. That will speed up exhaust gas velocity (including on your left side muffler). Here is a video that goes into more detail on the subject- th-cam.com/video/pr6z00gL5Yg/w-d-xo.html
What about use of a couple of night to shorten the eternal screw so there’s just enough in use a different size. Screw from outside to end to hold it down if you know what I’m trying to say.
No, I don't know what you're trying to say. Maybe email a sketch to us at Support@DKCustomProducts.com
OK another question in the documentation it says I think 1 inch to 2 inch of one and a half to 2 inches from the end that was at the end of the baffle or the end of the exhaust pipe for the end of the pipes end cap
You want to get as close to the end of the pipe as you can, when the energy pulse hits the outside atmosphere, that is when reversion occurs, which is what slows down exhaust gas velocity, which limits the intake charge, which reduces power.
Here is a link to a good video explaining...it has an excerpt from S&S showing how the pulse slows down velocity, reducing power.
th-cam.com/video/pr6z00gL5Yg/w-d-xo.html
What size do I need for TAB 50cals with Zombie baffles and Zombie Torque Rings? Do these fit on the baffle or will I need to remove the Zombie rings to install on the tips? Any way to run these and keep the Zombie rings installed for looks?
Yes, you can install the TTI's behind the Zombie Ring. I can not see how the Zombie Ring will prevent the TTI from working. You can get the 158 TTI for your set up to install inside the Zombie Baffle.
You can see the 158 TTI's at this link - www.dkcustomproducts.com/thunder-torque-inserts-158-model-family-dk-tti-158.htm

Hello how are you guys doing today I get up this morning went for a ride on my bike 2017 103 and it started idling high and I have not been able to get it down to where it normally idles any idea what I need to do thank you have a great day
There are a whole variety of reasons this could be happening. First thing that comes to mind is an intake or exhaust leak.
Another thing is talked about in this video, which is pretty common- (high idle discussion begins around the 4:28 mark) th-cam.com/video/T2aG284iCKc/w-d-xo.html

Not sure what you last did to the bike, but if is putting in TTI's, there is nothing about installation of TTI's that would affect the idle (unless an exhaust or intake leak started from the work being done)
2 1/2 inch baffle keep the baffle in and remove all the stuff around the baffle and reinstall it in install your product into the baffle so it’s inside the muffler flip on whatever you wanna call it and it’s screwed to the baffle inside so you don’t see nothing outside to look through it how’s that thought?
Yes, that is exactly what we said and showed an example of in the video. That is a great way to install the TTI's if you want to keep the baffle in the muffler...and you don't even need to remove that batting from around the baffle if you want to leave it in. This is shown at the 1:08 mark, and then explained and shown at the 5:30 mark.
Can you help I have the screaming eagle 2 slip ons with the baffles out its from a 2000 Sportster can you send me a link too the ones I need thanks
The 158's at the following link will work well in that application.

i run the bassani big bore my tuner says its a big pipe hurts a little down low
how about performance pipes like d&d bassani wonder how these help
with these pipes
They work very well with them, giving a solid 7-10% boost in low and mid range torque.

I have vance and hines 3" slip on with standard baffle. Would it be better to take baffles out and use TTI's or with baffles in?
You will have more low, mid and top rpm power with the baffler removed and the TTI's installed. It will also be a bit louder, and deeper.

ok, ok I have SharkRoad slip ons for my 2023 SG Special. They sound ok, a little more roar than original, so here is the issue. The slip on is roughly 4 inches in circumference and the baffle is right at 3 inches. So my ? is, or perhaps the answer is to remove the baffle and attach the TTI to the baffle and then put them back into the slip on (pipe). and cut down the screw if needed to fit into the housing. ???almost there guys, I do like the product. just checking thanks
🤙🤙🤙
@@edwardmarin-8pqb141 You can definitely use a 158 with the baffle, using the TTI to secure the baffle instead of the bolt the current secures the baffle. Or you can remove the baffle and use a 258 in the can.
If I take a picture of my exhaust you can tell what I need for the tti! Where do I send the picture?

Are you installing into baffles? What is the inside diameter 1-2 inches into the exhaust?
@@DKCustomProducts Sorry for the delay. Inside diameter of the baffles is 2.5 inches.
What’s the purpose of the insert?
To add low and mid range torque, while not restricting higher RPM power.

Too bad they will not work on my stock Freewheeler...
No, TTI's are of no benefit on stock mufflers that have not been modified. Below is a video link on why and how. Also explained in that video is why OEM exhaust robs power and build damaging heat.
th-cam.com/video/pr6z00gL5Yg/w-d-xo.html
HOWEVER, your stock mufflers, with a slight modification, will out perform 90+ percent of all the aftermarket slip-ons available. Here is a video link showing that- th-cam.com/video/cOs1-bTPycU/w-d-xo.html
