Great video.
Best options I've seen.
Staying stage none for the serenity of riding into and out of campsites at zero dark thirty without being a jerk.
Thanks, glad it was useful to you. Yeah, campsites at zero dark thirty are not where you want to be brapping the pipes! You might like this video- ua-cam.com/video/RZiGfcvw6fw/v-deo.html
Different approach. After you drill out the baffle, Big City Thunder QQ 1 7/8" baffles fit perfectly. They sound great and I didn't lose any low rpm power.
IMO, sounds best with the baffle out and nothing more done
Every person likes different sounds. The TTI is more for performance than sound although it does produce a bit deeper sound/rumble all the way through the RPM and Throttle range.

Like they say, it was short and sweet!! Great video.
2016 Road King and I removed the baffles. No issues whatsoever.
Very good! Thank you.
I’ve thought about this mod, however if I get done for the loud pipes and I need stock ones for a roadworthy, then I’m kinda screwed !?
You do not need stock pipes for the TTI's to do their job (eliminating reversion). You can see a written report on Exhaust at this link that you may find interesting - www.dkcustomproducts.com/harley-exhaust-myths-and-facts.htm

With the factory tapered muffler cut back 2 3/4", is there enough clearance to fit this insert 1/2 way into the muffler? These inserts are a lot more trick than the "Screw and Bolt" method I used to do back in the day. Thanks
other than the possible different size hole saw, is the procedure the same on a 2021 FLSL softail slim? other videos show fiberglass wadding
The concept is the same. Here is a video where we take the baffles and wadding out of a M8 Softail stock exhaust that you may find helpful - ua-cam.com/video/uSC1PBAgZmE/v-deo.html
The baffle is what holds that wadding in so if you do not remove it when you remove the baffle it will just come out going down the road in the future.

letting it blow out on its own is very tempting,will have to think on it after the baffles come out
thanks for your time ...I would be head for disaster without you guys
Glad to help! Thank you for your business and for commenting! 😎 MB
Very interested, but wish the actual install was shown. Is it that easy or that hard? I may be placing my order this weekend.
I think that, slipons + high flow filter.. whether it's a stock look or round SHOULD require richer fuel mix. 883's come dry from factory to please emissions, so the Xied's enriches the mix quite a bit 6% making the engine sound, feel (cooler) and respond WAY better than stock.
Dont you need to have the carb rejetted?
Sounded best stock. My opinion.
Everyone is entitled to their own opinion! Thanks for sharing! 😎
Is there a video out there that lets you hear it without the mufflers at all? Wondering if I could just take them off my 2007 Street Bob.
it is a loud blubbery sound, and importantly, there will be a serious drop in power...you could put the TTI's in the end of the headers and have all your power, plus more, back.
Very interesting for less than $20. I'm going to look at my exhaust when I get home to see if the baffles have been removed off my bike. I always assumed they were but, after watching a few videos today now, I'm not sure.
I checked it out & my baffles are gone. Is there a video that shows how to install the TTIs?

I assume you need to remove the mufflers to put them in correct? My pipes look similar to the ones in the video with a smaller opening at the end of a larger pipe.
I don't see why you'd go to all the trouble to remove stock baffles just to install Thunder Torque when you can install Screaming Eagle mufflers & get same results. You can find them cheap re-sale on web wont void warranty , violate state & fed laws & don't require re map of ecm. Can't do this on 2013 stock mufflers anyways Harley change the end design so you can't cut them out
lol I like the amo box saddle bags! And I usually don't like saddle bags!
I'm take u parts tuder torque
Have question u remove or Made same Sistem for both Pipe?
Yes, the same TTI is used in both slip-ons. Feel free to call us or email us with any questions. 662-252-8828 or Support@DKCustomProducts.com
Thanks tomorro call u guys..for make cuestión
Hi have question i'm have sporters 883 05 custom.when me Made does need change Jets or some in carburator? I'm like sound Q torque
And how long is deliver for part thanks
You do not need to make changes to the jets, as long as you are running the stock air cleaner. If you already have made changes to the jets for a free flowing air cleaner and exhaust, you do Not need to make any changes to the carb. Only if you have a free flowing air cleaner and stock pipes, then you will need to make changes to the carb (jets). We ship within one business day of receiving the order. How long it takes, depends on where you are. No where in the USA should take more than 3-4 days.
sounds better with the baffles on!!! does'nt sound like a harley without the baffles
Can you hole saw like that on catted pipes I have a 14 iron and it's catted
We have not done it. I am not sure you can get the baffle out that way, & if you want to get rid of the cat, it is probably far more trouble than it's worth.
I don't mind the cat I just was curious if the hole saw method would work for the baffle removal and I love you guys you reply to all my dumb questions and are helpful
CursezZz
Unfortunately we have not had a look at the inside of the new Sportster mufflers to see if the baffle can be removed while leaving the cat in...not sure if the cat is connected to the baffle or not.

Check out this NEW youtube on a step by step on converting stock mufflers that have the cat in them.
Converting Stock Harley Exhaust w/ Catalytic Converter in Slip-ons
hey your video says it is private.... make it unprivate please
Do any changes need to be made to the carb or engine?
No changes to carb or efi map needed. The Thunder Torque Inserts speed up exhaust gas velocity, reducing engine pumping loss. Result is more power without any other changes needed.
Even if my bike ud fule ejected
Trevor Hanes If you change only the exhaust, you do not need to do any change to the computer (ECM) that controls the system.
Many who upgrade the exhaust also go ahead and upgrade the air cleaner. However, it is NOT necessary, it is just something that people like to do.
If you upgrade the air cleaner & the exhaust then you do need to reprogram the ECM. We recommend either the XiED (see this link- www.dkcustomproducts.com/XiED-Fuel-Enrichment-for-EFI-Harleys-Plug-n-PlayMore-Details-DK-XiED-NR.htm ) or a PowerVision from Fuelmoto.
With just the exhaust you are ok with the stock factory tune. The bike will run better with the XiED, but that is true regardless of the upgrade in exhaust.
Yes you need bigger Jets and a better air filter.
isso só funciona para ponteiras sem o catalizador ,pois o desenho interno é bm diferente sem o recheio.
esqueça para as injetadas catalizadas.
Como saber se a minha tem ou não catalizador ?
Will it screw up the compression in my engine?
Nope
A 1/4 in. bolt through the rear of the muffler will do the same thing. And improve the torque.
this is only possible to do in harleys produced before 2010 who has no catalyst inside mufflers.
The guts of any HD muffler can be removed. Models with catalytic converters are more difficult, but definitely possible.
DKCustomProducts yea if somebody is ready to cut muffler in a half ;) and weld it back again after taking buffle out. Am I right?
Thank God I have 2008 sporty :)
Check out this video link on how to do with catalytic converters- ua-cam.com/video/r2Mx1jV8Yyo/v-deo.html
Do I need to remap the fuel system
Just adding TTI's does not change the AFR in the combustion chambers, so if that is all you're doing, no. But, if you have a highiflow air cleaner AND you are going from stock exhaust to free flowing, AND you are still running the stock tune, then you would want to richen it up some. Here's a good report with more info- www.dkcustomproducts.com/overview-of-efi-optionsxied-piggy-back-flash-tuners-dyno-ov-efi-opt.htm
Everyone has a different take on what is good sounding to their ear.
Does not mess with the compression or AFR.

There is no thunder torque W on the site, where they replaced?
+Alfredo Fabbricatore You will need to click the drop down, and choose the W model. Please let us know if you need anything else. Happy Friday!!!www.dkcustomproducts.com/Thunder-Torque-Inserts-118-Model-Family-DK-TTI-118.htm
+dawn jones In this particular application were the 118s used? I want the same sound and I am not sure what size. I have pretty much the same bike to take care of...
+Alfredo Fabbricatore Hey Alfredo,
Email us at support@dkcustomproducts.com I will need to know what the inside diameter of the exhaust is before being able to say for sure. Please make sure to include what bike, and exhaust you currently have. Also, this link will help with understanding how to choose the right size:www.dkcustomproducts.com/Choosing-the-Right-Size-Thunder-Torque-Inserts-DK-TTI-FIT-FAQ.htm Hope to hear from you soon. Happy Friday!!! Dawn :)

I will guarantee that stock made more HP on the dyno. Drag pipe sag, exhaust scavenging, and velocity hurt power.
The more open a pipe is, the more HP it will make on the dyno. There is definitely a DROP in torque when opening them up...because of reversion. That is what the Patented TTI's address. They reduce the reversion, resulting in an increase in torque. These opened up stock slip-ons produce more HP and more Torque than stock...both felt on the street, and seen on the dyno. Check out all the dyno charts at this link- www.dkcustomproducts.com/Thunder-Torque-Inserts_c57.htm
DK .Custom Not true, size of pipe matters because of velocity, the torque washer may help with reversion slightly, but it's not a cure. It can not keep the exhaust pulses from going back to chamber. I don't care what the manufacturer claims. I have seen it on the dyno many times. It's cool if you like the sound better, like they say, less power to ya! FYI you could have welded a washer on a bolt, ground a slot in it so you could rotate it for less than 20 cents. It would be the same piece of crap as the tti and you would have more money in your pocket.
No desire to get into an internet dispute with you Kris. But you have seen it on the dyno even once with a Thunder Torque Insert. The patented shape of the TTI is Much More effective than the lollipop design we all used (that you describe) for years.
Nice vid, my latest vid is a tutorial on how to install Xied fuel management + high flow K&N filter but keeping stock look, and sound with just Rush slipons and tornado baffles on my 2013 iron 883! check it out!
liked it stock better
There's only scavenging when there's a collector, Multiple cylinders
You can't do that with 17+ with cats in the exhaust pipe .... LAME. BS LIES
You can take out the baffles and install the TTI's and it will increase your low-mid range torque and change the exhaust tone even on a 17+ model. You can also remove the CAT if you wish to that will help with the felt heat from the exhaust.
Here is a video from a customer with a 2019 Touring model that removed baffles and installed the TTI's that you may find interesting - ua-cam.com/video/DKaagGXxUzg/v-deo.html
And here is a video of a 2017 plus Softail that has the cat in the slip-on's where the baffles were removed and the TTI's installed- ua-cam.com/video/tOMI3yBz_9w/v-deo.html
