Another great video from DK!
Glad you enjoyed!
Appreciate the kind words. 👍😎👍
Thanks for the video, you addressed a quality issue with logic.
Glad it was helpful, thanks for watching! 👍
I hollowed my stock slip ons out my bike was so loud was going to throw them out until I heard about the ttis just installed them today I am so impressed with the sound couldn't be happier and they quit it down just enough I used the258 4 inch exhaust
Very nice.
Glad you are enjoying that deep tone, and hope you have noticed a nice increase in power.
We appreciate your business and comment! 👍
This reminded me to send in my picture of my exhaust. Took picture months ago and forgot. Lol. Another good video guys.
Thanks man. Looking forward to your pics. Glad you are liking the videos. 👍
Just installed some 258, in my stock mufflers on my 21 street bob. I cut about an inch back so the baffle plug could come out, but left the cats in. The TTI's definitely made the biggest difference, got all the sound and still legal to boot.
Good deal, glad it is working well for you. 👍😎👍
Thanks for your business, we appreciate it.
Thunder torque insert, make my bike feel like I got a flash tunew, , feels great, thank you
Great to hear! So glad you are liking your product.
Thanks for commenting! 👍
It's funny you mention it because I just had my V&H baffle and endcap rip out of my pipe while riding so thank you for making these so I don't need to spend hundreds to get another set of endcaps and baffles
I hate that happened to you, but I am glad that we have a cheaper item that will give you back your low-mid range torque and not break the bank!
Thank you for your business and for commenting! 👍😎👍 MB
I've used these in my last 5 bikes (3 of them in my garage right now) and a huge believer in them. I can't say how many people I've recommendes them to on various forums and Facebook groups but it's a lot. Lol
Man, that is great to hear. Glad you have gotten good benefits from the TTI's on your rides.
Very appreciative of you sharing here, and spreading the news to others. Thank you.
About to install these!
I believe you will be well pleased. 👍
Thank you for your business, we appreciate it. 😎
Just ordered a set for my ol' FXR to try out. I lollipopped my Sporty and if satisfied I'll have to switch them out as well. Looking forward to my order delivery. Cheers! cb
Nice. I believe you will be well pleased with them. 👍😎👍
Thank you for your business, we appreciate it.
Love the TTI, Have had them in all my HD exhausts. 👍
That is great! I am so glad that you enjoy the benefits of having them installed! Thank you for your business and for commenting! MB
@DKCustomProducts I just got a 24' Softtail std 107, you have any links to the stock slipon mods, I want to put the TTI maybe after removing the stock inner mufflers or muffler mods you would recommend??
Here is a link to a video on the best way to choose what exhaust is right for you. Below the first link is another link on how to mod stock exhaust and put the TTI's in. This is something you may be very happy with, or at the least, it will give you a better sound until you find the exact exhaust you want. KP

This thing worked great in my 2006 110ci Yamaha warrior, especially noticed a big change in moving off at a light, instant torque from idle. I use cobra swept header pipes and vh strataliner collector to get a up swept 2 into one. Im surprised the thing works as well as it does.
Glad you are seeing the benefits of having the Thunder Torques installed. Thank you for your business and for commenting! MB
You guys rock 🤟🤘
Thanks man!
Appreciate your comment! 👍😎👍
To anyone considering these things, I can't recommend them enough. After I installed them in my Vance and Hines Straight Shots (installed on my 2005 HD Night Train), the significant torque dip off idle was completely eliminated, and the torque curve was smoothed out and extended. The Straight Shots also have a raspy tone to them. The TTIs got rid of the rasp, and gave the tone a nice deep rumble. On top of all that, you won't find a better company to deal with than DK Custom. Great products. Great people.
Cheers!
Hey Clammy,
Thank you for the review and kind words. Much appreciated. 👍😎👍
I put these for my 05 Electraglide Classic with no name slip ons. At first I was happy with the sound but the power didn't feel quite right. I went so far as to remove them and put my baffles back in. I emailed tech support and you guys were very helpful and responded quickly, It seems that the bike just needed to settle in with the new exhaust flow. I put them back in and now after a couple of 100 miles, it runs great, sounds great and I'm happy with them. I track my MPG and if anyone is interested the TTI didn't effect my MPG one way or the other.
That is a great report. Thank you for sharing it. Good to hear you are enjoying the sound and the extra power. 👍
What did it do to the sound?
Good points, these can help the torque and mid range and decel popping of open ended pipes (if the OEM mufflers have been modified or you have no or low restrictions in your Aftermarket exhaust).. from my own experiences , They did help torque, mid range (subsequently fuel mileage too) on 2 out of 3, of my large vee twin bikes.. Of the bike it didn't help the torque or mid range (full true dual Vance and Hines exhaust with Titan 4.5" mufflers) .. I saw no fuel consumption increase or decrease, but it did seem to hurt my horsepower alittle noticed in the higher RPMs.. so out they came.. Good point about the fender washer I would mention if your insert stem is mounted upward in the tube (rather than at 6 oclock location) that the moisture collection over time will not be near as problematic.. If you create too much blockage, you will notice a loss of Hp before you notice a loss of torque. If you are experiencing decel popping (not due to a poor or leaky joint) then that a good sign you need one or a set
Thank you for the reviews.
On your bike with the 4.5 Titan mufflers, you should be able to see an increase in low and mid range torque without hurting the top end by rotating the angle of the TTI's a bit.
From the instructions-
"TORQUE: The Increase in Torque is accomplished by reducing engine pumping
losses, increasing exhaust gas velocity and increasing inertial scavenging. The unique combination of materials and design of the Thunder Torque Inserts™ are able to accomplish the above.
Installation angles have a direct impact on how much more torque you will gain.
Because each bike is different (air cleaners, fuel management, headers, slip-ons) there is no single adjustment that is best for all.
In most cases centering the Thunder Torque (height wise) in the pipe is optimal (it does not make a significant difference if it is a little off center, but as close as you can get is best). In some instances our LT (Long Thread) TTI can be used to get it centered.
90%+ of the time the best results are when the threaded part of the TTI is closest to the engine (with the cupped part closest to the tail end of the exhaust)."
@@DKCustomProducts Thank for the tip.. however though my whole exhaust was aftermarket on my 2020 M8, 107, with No fuel management, and also true duels, did not have decel popping, and my fuel mileage was consistently 44-46 mpg, that was a good sign that more restriction might not be beneficial, but I tried it any way so I could share my experience.
@@ut1004bp Thanks man.
I wanted to love these!! I installed mine yesterday. I have the older SE 2 slip ons I took the baffles out these make my 88cu louder but sounds good!! Only gripe is I feel like I lost my low end power!! 🤷🏻♂️ I’ll probably ride with these for a bit then go back to my baffles other then that I do love the sound
You should gain low-mid range torque with the TTI'S. How far in do you have them installed into the slip ons?
Please feel free to contact our Customer Service with pictures and we can help you trouble shoot and get your mid-low end torque back.

You may want to try different angles with the TTI's. MB
@@DKCustomProducts Just set them closer to a 45 degree angle for whatever reason my bike seems to like that better 🤷🏻♂️

Thank you for your business and for commenting! 😎MB
Good info for sure. I do not want to hear anyone complain about popping exhaust after installation. They need to understand that adding fuel will not cure this. The problem being the exhaust baffles and fiberglass packing muffled down ( choking out performance and the igniting of unburned fuel in the exhaust) I used homemade lollipops for years in the 80s on many exhausts, it never cured the popping tho it did help the low end and mid range for sure.
Keeping in mind that DK Customs has done way more testing and real time numbers with their in house product. Well done @ D K Customs
Hi Jack!
Thank you for your comment and experience. Always appreciated.
👍😎👍
I was told by a tech at a performance shop that reversion travels on the inside of the outter shell of the muffler. That contradicts what you are saying. His logic for his theory was that's why reversion cones that fit in the head pipe where they attache at the cylinder head trap the reversion out of exhaust port.
I've already purchased a set of TTI, will install in the near future.
Would like to get your take on that theory.
Thanks
Does this tech have any dyno charts that support his theory? We have done quite a few tests on torque cones and have never seen any measurable benefit from them.
Here is a video explaining how reversion works (and it is not just traveling along the outer shell) - ruclips.net/video/pr6z00gL5Yg/видео.html
And, of course, we have dyno charts showing the significant gains of low and midrange torque when using the TTI's. You can see some of them at this link- www.dkcustomproducts.com/thunder-torque-inserts-118-model-family-dk-tti-118.htm
Hey Guys, I have a question about the TTI's. Quick summary of my bike. 13 Ultra, Full Sac headpipe, V&H 4" Twin Slash slip ons WITH V&H quiet baffle inserts. I assume I would remove the inserts in order to install the TTI'S? The decel pop is what I wish to eliminate. I do have a PowerVision that I ordered from you guys that will be installed. Also going with your 606 with the Transformer EBS. Thanks guys for all the great videos. Looking forward to warm weather. Just got 18" of snow here in Minnesota. Send some warm weather our way! Take care.
Decel pop is all about the AFR in the pipes (this is NOT the AFR in your tune).
Once you install the Power Vision and the 606 with the Transformer EBS, your decel pop may be gone. If it is not, pulling the baffles and installing TTI's will reduce or eliminate it. But if you do it now, before the other things you're going to do, it may not do what you want regarding decel pop.
Regardless of decel pop installing the TTI's, with or without your quiet baffles, will increase low and mid range power.
See this video on the subject- ruclips.net/video/I_djBYYYu28/видео.html
Thanks for your business, we appreciate it. I believe you are going to very pleased with those parts you're going to be installing.
Hope it warms up for you up there! We've been having our temps just between 75 F and as low as 25 F....pretty soon it will be warm all the time!
I just had a set of W158 Thunder Torque Inserts installed in my 3.5" Rinehart slip on mufflers. This was done by my local Harley Dealer. I emphatically told the service guy that they need not be perfectly centered, but to center as well as possible. Well he has them bolted down tight to one side. So there is clearance you could say at the 9, 12 and 3 o'clock positions, but not the 6. I asked him to just adjust them up a bit. Not a lot of stud thread left as of course he cut them off. He said he could, but the Dyno was absolutely perfect, and didn't feel it was necessary (S & S Cam upgrade also). Just wanted your opinion. Thanks!
Do they work best when closer to centered? Yes. Is the difference significant enough for you to feel? Everyone is different in how they ride. Even the most aggressive rider may not feel the small difference.
I'm sorry to hear that he did not provide the service you requested, if you have the time and the patience to have him try and do it again, the right way (per your request, and the instructions that came with the TTI's) it may be worth it, or you may not feel it at all.
Okay, thanks. I will ask for them to be centered. Might not be in your wheel house, but will the dyno tune need to be checked afterwards?
No, if the tune is good now, it will be good after they are centered. Only reason for it to go on the dyno is if you want a chart.
@DKCustomProducts Okay, thanks again. While most people wouldn't even notice that they are there, they just look better centered.....
True.
Gre8 job on Why one should NOT be buying Commi Sh#t ! Amerca 👊
Thank you, glad you found the video interesting/useful.
It is quite interesting how many questions/comments we get from Harley owners that bought cheap knock-offs and then don't understand why it does not work.
The parts were not made by riders, were not tested by riders, and it is not surprising that the stuff does not work well, or last well.
I should be able to remove my baffles on my V&H short shots and add these without retuning? 2014 model Seventy Two
If your tune is already good you will not need to retune just from installing TTI's.

I love your videos but with the Thunder Torque you haven’t specified if your supposed to install them cup facing in or out and are they supposed to be installed in line with the exhaust or slightly crooked or slanted.
Here is a link to a page with a lot more info-

Here is a link to the instructions page- www.dkcustomproducts.com/media/wysiwyg/Updated_9_16_22_Thunder_Torque_installation_instructions.pdf
Angle/slant is addressed in the above instructions.
The cupped part faces the exit of the exhaust. This does two things-
1. The cupped design does a better job of stopping the reversion/energy pulse from returning back up the pipe.
2. The back of the cup (cone shaped) speeds up the expelling of the exhaust.

I have a 2020 Harley Heritage with Cobra Neighbor Hater slip-on mufflers. Do I need to remove the stock baffles? is it better to remove or leave them on?
You do not Need to remove them, but for the most power, best to remove the baffle, but you will still get a nice bump in power, even with the baffles in.
Here's a video you may find interesting- ruclips.net/video/H681dl2X_f4/видео.html
The dealer installed the W258 Inserts into my 3 1/2" Rinehart slip on mufflers. It is really crammed in there. I did send your Support Division an after photo. Natalie (who couldn't be nicer), said they did look tight, but suggested I just turn them a bit sideways to allow more air flow. I think I should just order a set of W158 Inserts and swap them out. My bad for not ordering more carefully. Do you agree swapping out for the smaller size is the best way to go?
If you have 3/16" gap, that is good. Also, you can rotate the TTI just a little to see if you like the sound or power better that way.
Here is a link with info that you may find useful- www.dkcustomproducts.com/choosing-the-right-size-thunder-torque-inserts.htm
You can certainly try the 158's, the only way you will know which size (and adjustment in angle) is to try them both. Myself, I would start with the 258, like you did, and play around with the angle...but, if extra expense is not an issue, trying them both will give you the best way to know which sound and power curve you like best.
@@DKCustomProducts Thank you! The wife is still rolling her eyes, but I will not be able to sleep at night with those huge 258W Inserts wedged in there. Fortunately they are very reasonably priced, so I will just chalk it up to experience and not checking out your size chart closely enough. One more question; will the smaller 158W Inserts skew the Power Vision 3 Tune and Dyno Testing I just had done?
It will not skew the tune in any measurable amount, but you will have more low and mid range torque.
what about the torque cones that fit in the head pipe at the exhaust port
All the seat of the pants testing and dyno testing of torque cones, installed at the top of the header, provide little to no benefit.
The whole principle of the Thunder Torque Inserts™ is to Increase Exhaust Gas Velocity by reducing reversion. The only place that can happen is at the end of the pipes, where the exhaust gasses exit into the atmosphere.

You can use the TTI's with your 4" Rinehart's. If you are leaving the baffle in place you would need to measure the inside diameter of the baffle to determine the size TTI's you need.

Bought this insert June or July of 2021, i used all the hardware that came with it. Came loose, tighten it back up. Went on a run to penn came loose again and tore a hole in my exhaust and it's still in penn some where. I sent dk a email and never heard anything back from you guys. Have not purchased another one yet, but any advice on keeping them tight. My exhaust is Vance and Hines big radius 2 into 1
When I read your message about sending an email and not getting a response I asked Customer Service to research our inbox, junk mail, spam, and this is the response I got-
I can not find an email from him. I looked up Vance and Hines big radius 2 into 1, pro American, tyranny, came loose, tore hole. I can not find anything from him.

Regarding keeping them tight, 999 out of 1000 the washer, then lock washer then nut is all it takes. However, if you used that and it did not, then use a washer then a nut that is tightened all the way down, then put another nut up against the tightened down nut. Hold the first nut in place, then tighten the second nut up against it.
@@DKCustomProducts jam nut
Guys, I have V&H Monster Rounds. They have an end cap on them. So I would remove the end cap and install 1" - 3" back of the actual pipe is that correct?
I would place the TTI's as close to the end caps as you can. Probably 3/4" to 1" from the inside end of the end caps, in the pipe.
Appreciate your business, and I believe you are going to like the improvement. 😎👍

I just ordered mine a few days ago. Waiting on them to arrive to install. I have VH Straight Shots, I hope to use them with the baffles installed, I ordered these instead of the quiet baffles so hope it works. I called in and asked if they would work that way, the person I spoke to was unsure. If the threaded stud is too long it will not fit past the heat shield. I guess I will find out. I will be able to tell if they will fit before I open them by looking at the stud size. Can I return them if it doesn't fit?
They fit.
On V&H "full coverage" shields, there is almost 90 degrees that is NOT covered. Using that area is the easiest install, since there is not heat shield to contend with.
The other way, which many folks do, even though it is much more work, is to make sure the threaded section is short enough to fit between the outside of the exhaust pipe and the inside of the heat shield.
This may require cutting down the threaded portion some.
You may also want to use a low profile fun instead of the one included.
If you look at the following video, it is some Short Shots on our Project 48. There are no heat shields installed in the video (we were doing a lot of testing that day), BUT, if you watch the video you will see the TTI's installed, not at the top or bottom, but at around the 7-8 o'clock position.
This is where it was easiest since there is no heat shield that goes there.
If you are wondering if the thread diameter of the TTI is the same as the baffle holding bolt on the V&H, they are not. Below is a copy and paste from the online instructions.
"V&H is the only company we know of that uses a non-standard size hole for the exhaust baffle bolt. It either needs to be drilled out, or just drill a new hole for the TTI’s. Thunder Torque Inserts™ can be installed in an infinite # of positions to accommodate all different tunes and desired sound."
@@DKCustomProducts thanks for the reply.

Should you put them in both mufflers or just one?
Both.
You may find this link interesting/useful- ruclips.net/video/6EdSBP2kZLYv/видео.html
Now 1/2” to 3” from end cap or end of pipe before end cap. Sounds like 1.75” in would be 1/2 way point as well.
You want to limit the reversion from going back up the pipe, so the closer you get to the exit point, into the atmosphere, the better. More than 3" from the exit and you start to see a reduction in benefit.
Here is a link to a video that you may find interesting/useful-

I have 2022 11t4 heritage with freedom long shots don't like the baffles will this be ok for it
The Thunder Torque Inserts™ will noticeably reduce the decibel levels and reversion. The Patented design will produce a bit deeper sound/rumble and more torque.

Can I remove baffles and replace with these
You can! MB
Is it ok if I bought a size too small? I bought the 118 cuz I thought the 158 might be too big but I guess I was wrong cuz the 118 only covers about 55%-60% of my mufflers inner diameter. Does that mean I won't get any benefits or maybe less benefit? My mufflers are 2 1/4 inches but inside I believe is 2 inches maybe a hair smaller. I get almost 2/3 coverage having them straight up and centered as recommended. I haven't installed the mufflers on my bike yet so idk if ill benefit from any sound change and power. Have any insight on this? Will I be ok and am I sacrificing power and sound?
It is not going to hurt anything! Of course you will get better benefits from it being the right size! You can email our customer service at Support@dkcustomproducts.com and let them know you need to exchange them and they will help you out with the exchange process! Thank you for your business!
@@DKCustomProducts Thank you for your help. I'll probably just order the 158 and keep the 118 for future use if I need them. Doesn't hurt to have both sizes so I have options. I didn't realize that my muffler tips narrowed at the end so I measured the wrong diameter cuz my tips are 1.75 inch but my muffler end where these would screw in is actually 2 inches. Thank you.

What position is best most I hear is paralleled what’s your thoughts
Below is a link to the installation instructions which are found on the product page here- www.dkcustomproducts.com/thunder-torque-inserts-158-model-family-dk-tti-158.htm
Installation link- www.dkcustomproducts.com/media/wysiwyg/Updated_9_16_22_Thunder_Torque_installation_instructions.pdf
Copy and paste of a small part of the instructions regarding position-
The Thunder Torque can be installed facing forward or backward or at any angle in-between to give you your desired sound and best torque. All of our testing has shown that the most power is achieved by installing it with the threaded stud Closest to the engine, meaning the cupped part of the TTI will be closest to the tail end of the pipe.
So putting it at 90° another words, if you looked up the tailpipe, you’d see the circle the cup, and the threads will be behind facing into the pipe?
How do use these on v&h super deluxe slip in’s for Harley trikes? The tips are oval., not round.
There is no difference in installation, and they work well at stopping reversion and speeding up exhaust gas velocity, as well as deepening the tone, in ovals, just like rounds.
At first this video linked below may not seem relevant, but I believe if you watch it you will get some insight on options to installation on your V&H.

Hey guys help me out. I have a 2013 Twin Cam 103, Electra Glide Classic FLHTC, what’s the best high flow air cleaner you sell. Maybe give me a link with everything I need. Right now mine has no flow unless something is sneaking in behind. Gotta be chrome.
Hey Stephen!
The absolute best power is from the 636v with any of the EBS options in it. The Link is below, but it is not chrome-

A very close performer is the 828, it is also low profile, and it also has a Chrome cover option, again, with any of the EBS kits in it. The Chrome Cover option is linked here- www.dkcustomproducts.com/chrome-speed-fin-complete-hiflow-828-air-cleaner-dyna-softail-touring-trike.htm
All the other options are in this link (including some aluminum that can be polished to a chrome like finish)- www.dkcustomproducts.com/twin-cam-outlaw-hiflow-828-air-cleaner-complete-systems-72.htm

@@DKCustomProducts thank u guys. I’m the road these days, currently San Antonio. Now that I’m in the south I notice the bike running hotter.
@@LonesomeNomad137 Good to hear you are enjoying the road. Enjoy that warm weather...it is going to be getting cold almost everywhere soon!
If i have a 2" id do I use 1" tti
2" ID, I would use the 158's.
Here is a link to a chart to show which size TTI's for which size pipes and baffles.

I have Vance and Hynes Big Radius exhaust, but I don't see a way to install?
They can certainly be installed in the Big Radius Exhaust. You can email our Customer Service and let them know if you are keeping the baffles in or taking them out and they will gladly help you with the installation and what size you need.

Are these Tunable ? Tunable by turning the TTI ? Or should they be straight up and down in exhaust
Below is Copied from the instructions.

Tips on tuning your Thunder Torques:
SOUND: Desirable sound is totally subjective to each individual. To get the sound You desire
simply try different installation angles of the Thunder Torques. The direction the Thunder Torque
is facing will make a noticeable change in Tone & Volume. 90%+ of the time the best results are
when the threaded part of the TTI is closest to the engine (with the cupped part closest to the
tail end of the exhaust).
In many instances the removal of the baffle completely in conjunction with the Thunder Torques
will produce the most desirable sound.
TORQUE: The Increase in Torque is accomplished by reducing engine pumping
losses, increasing exhaust gas velocity and increasing inertial scavenging. The unique
combination of materials and design of the Thunder Torque Inserts™ are able to
accomplish the above.
Installation angles have a direct impact on how much more torque you will gain.
Because each bike is different (air cleaners, fuel management, headers, slip-ons) there
is no single adjustment that is best for all.
In most cases centering the Thunder Torque (height wise) in the pipe is optimal (it does
not make a significant difference if it is a little off center, but as close as you can get is
best). In some instances our LT (Long Thread) TTI can be used to get it centered.
90%+ of the time the best results are when the threaded part of the TTI is closest to the
engine (with the cupped part closest to the tail end of the exhaust).
@@DKCustomProducts The link you supplied says page not found on your site. The information you supplied after the link was very helpful . Thank you for your
Sorry, fixed it. 👍
Why don't you do a video on how to install thunder torque inserts on fishtail exhaust.
It is a universal part, as long as the insert is at or near the exit of the exhaust it will be effective.
The install is the same. Take the fishtail tips off, install the TTI and then put your fishtail tips back on.

I see many videos they installed in the head of slip-on, not the end of slip-on ?
I am not sure what product you have seen being installed in the head of the slip on, but the TTI's work at the end of the slip on.
Here is a written report on Exhaust that you may find useful/interesting - www.dkcustomproducts.com/harley-exhaust-myths-and-facts.htm

What is the effect of this project!?
The Thunder Torque Inserts are meant to eliminate reversion. Reversion happens at the end of the exhaust. Installing those thumb screws or TTI's at the head of the exhaust is not going to eliminate reversion, speed up the exhaust gas velocity, or improve torque.
Please go look a this written report on exhaust. About half way down the report it shows pictures and talks about how the TTI's actually help - www.dkcustomproducts.com/harley-exhaust-myths-and-facts.htm
Thanks! MB
But do they help you pick up the ladies?
I guess it depends! 😂
Put some on my Softail and couldn't be happier; the claims that are made are dead on!
Thanks man. We appreciate your business, and good to hear you are well pleased with how they are performing for you. 👍😎👍
