    I bought a pair to go in drag pipes, I had a 1275 build ported heads ,andrews cams, plus 2 inch id drag pipes I used the 118' and now I got my low end power and torque back. I don't care how they work but they do work. I did have to reset the cv40 but no problem. Thanks d and k.

    Bought these in hopes of smoothing out the throttle response in my Sportster where I had some lower midrange lag. Install was totally painless, product is well made and all hardware was included. After install the throttle response feels smoother across the rev range. No noted power changes, but as long as I didn't lose anything I'm happy.

    Pulled the baffles out of my ’02 Hugger and replaced them with 118 TTI’s in my drag pipes. Definitely noticed improved torque in low and mid ranges. Great inexpensive upgrade. Easy install. Recommended. ????

    2000 BMW R1100R straight piped boxer engine. Initially after picking my bike up after straight piping the exhaust, immediately had a hesitation and loss of power. The bike sounded great at low and very high RPM but sounded terrible at mid range, it was embarrassing. After installing the 118 model about 1 inch from the top of the exhaust, all the high pitch fart can rattle disappeared and it gained torque back when riding around in 5th instead of it just bogging and begging for a downshift! Very effective product so i went ahead and ordered 1 size up to see the difference, review coming soon on the step up version.

    Made well and easy to install. Actually I cannot tell a difference in the sound or performance with them installed, but maybe they do help with low and midrange torque? I do not have a before or after dyno to differentiate between the performance before and after.

    I installed this on my 1938 UL chopper to lessen my reversion issue. 2 into 1 exhaust. So far it seems to have alleviated the problem. As far as increased torque and HP it's hard to say as this bike is not that fast to begin with and had pretty good torque off the line. I would still recommend it and will probably get a pair for my scrambler dual exhaust.

    10 outa 10 would recommend, I've got custom exhaust some rather long minimally "baffled" fishtails that had a hard pap sound and with upsweeps it felt like it was right in my ear just driving me crazy, deceleration pop seemingly no matter how I jetted, a quick morning dropping in the Thunder Torque Inserts and I was sorted, tone calmed down, and no decel pop, should have done it from the get go.

    I changed my stock Tri Glide Ultra mufflers to modified HD mufflers from American Custom. They sounded better than stock, but didn't run well. Reversion was very obvious, and the power and torque were both 'off'. I added the 118 Thunder Torque Inserts about 3 inches into the open baffles, and reversion is nearly gone. Torque and power are up, throttle response is improved, and it's much more 'streetable

    Hi, DK folks are very pleasant to deal with and response is good I ordered the TTI 118s and installed on my Rinehart 4" set up on 08 road king. I was mainly to hopefully tone down the Dbs on the long road trips. Well that worked but after looking at my install I am going to order the 158s for hopefully even better outcome of both sound and performance. always experimenting.That's whait I call it when i screw up on the first go...lol

    I was skeptical, but for the money I thought I would give these a try. I had Tab slip ons I liked but the torque fell off when I installed them. However, I installed the TTI and the torque is back, and maybe a little better. And the bonus is that I think the slip-ons sound a little better!

    107 m8, I put on the Jackpot 2-1-2 exhaust. Lost a little torque. So, I installed the 118s into the baffles of the S&S MK45s. Got the bottom end back. Unexpectedly, seems the bike doesn't work as hard @ 70-90 mph, so I got top end also. According to my PV, lowered overall ET by 5-10°. They work. Didn't change the sound.

    The sound is incredible but I had to pull the baffles and all insulation. The only reason I gave them 4 stars is the installation is a pain. I had new Vance and Hines 300s and I had to drill new holes in the mufflers to fit and trips to hardware store to fab the bolts to work.

    Quality

    Value

    I didn’t really think these were going to make a difference but for the price I figured I’d give them a shot. Boy was I WRONG! I put a set of RCX slip ons on, didn’t do anything to the stock intake and had a big dead spot from about 1/4 to 1/2 throttle. The thunder torque inserts TOTALLY got rid of the dead spot. There wasn’t any noticeable change in the sound, which was awesome. I got the middle size for a 3” exhaust which tapers down to 2 1/2 at the tip. Put the inserts 1 1/2 in from the end using the holes for end caps. Had to drill out the end cap hole larger but the hole in the exhaust was large enough to leave alone. So about a half hour job. HIGHLY recommend if you want to leave your system stock except for slip ons. I can’t speak to any other set up

    This is my first Harley, 2002 Sportster 1200 Custom with one and three-quarter inch straight pipes. Very loud, and what I thought was fast. TTIs were easy to install, definitely calmed down the rumble, bit of a deeper controlled rumble, and the most impressive thing to me was the torque difference. It’s been cold here, I finally got a chance to get out to ride and I had to hold on tight. The performance difference was very obvious to me-seemed more powerful in the lower gears. The TTIs are a great inexpensive mod that really work.

    I just installed the thunder torque inserts and was surprised at the throttle response, torque and sound. there is no way you’ll get more performance dollar for dollar. If you’re worried about the sound of your open pipes this will just make the sound smoother while still having the open pipe sound. I am very pleased and will tell everyone I know that rides about this product. I have a 2001 sportster 1200 with custom (I made them myself) very Short two into two pipes.

    I ride an 09 Iron with unwrapped Rineharts. I've upgraded it to "Stage One" with a DK Customs 828 air cleaner, ViED fuel management devices, and changed out my pulleys to a 32/66 setup. I ride freeways fairly often. I lost some low end get-up-and-go doing that. These little inserts, installed in the baffles themselves, have changed the game. I got all my low end torque back, and the sound is really nice. It took the harsh tones and mellowed them, yes, but the added low end power is where my smile is coming from. Customer support was awesome. Their advice made the project simple, easy, and... simple?? Let's go with painless. The hardest part of this operation was getting the baffles out. (smiley face here) Thank you DK Customs for your help, once again.

  32. Use Thunder Torque Inserts if you Lose a Baffle 0 people found this helpful

    Value

    Purchased 2003 883 Hugger with missing baffles in the 2" Vance Hines staggered pipes. Very loud, low power, with back fire and coughing. Researched Thunder Torque Inserts and carburetor adjustments. Ordered the 118, installed in hole nearest the ends, had to drill available hole slightly larger for insert to fit. After install, already noticed a difference bile sounding nice and strong. Used an angle cordless drill/driver to drill out and removed air/fuel mixer screw cap to slightly adjust the mixer to decrease the lean condition (small change-big difference). Backfire is gone, no coughing, bike runs and sounds great. My son is happy and can feel the increased power.

    I had a more complicated setup on my z900rs but I was able to take out the baffle, drill into it, install the TTI, and noticed an immediate recovery in my low end torque. I had a 4-2-1 exhaust and switched to a 4-1, which killed some of my low end torque and "streetability". The TTI fixed the issue. I would highly suggest them to anyone looking for a low cost, high quality solution to their problem.

I did have a chance to go for a quick test ride and can say that the bike performs and sounds beautifully.

    I changed my 2003 1200 XLC stock exhaust to a set of drag pipes until I get a DIY kit to build an exhaust I want. The exhaust was a bit too loud for my liking and I lost power, the TTI's restored low end torque and made my exhaust a much more likeable tone. If you're thinking of buying them, just do it. I will put these on my exhaust I build in a few months.

    I installed some Python 2.5" slip-ons on my '19 Iron 1200. They are "loud" and I too noticed a drop in low-end torque as some others have said. Also brought on some decel pop(which I don't mind too much). I saw some people recommending these TTI's from DK and thought I try it out before dropping money on a tuner and such. Glad I did. They have cut down on the decel pop and have helped with my low-end torque loss. Plus they have somehow made the exhaust sound better. Not quieter but maybe a deeper sound. Excellent product.

    Riding my 2006 CVO Fat Boy is even more fun now with the 118 Thunder Torque Inserts. They make the bike sound vintage like I'm on an older scoot of yester year. Taking off from stop lights is easier too with the added torque and horse power. The TTs are everything everyone says they are! Hope all this stays good forever. I currently have baffles in my V&A Big Radius pipes. I may remove them and upgrade to the 158s for the sweetest sound! Next stop, Lord willing, is to order the lifetime oil filter. :-)

    Value

    So I’ll be honest, it took a good deal of internal coercion to drop almost $40 (after shipping) on a couple small pieces and steel and associated nuts/washers. I really didn’t think they would work, I was sort of rooting against them. I was wrong, completely. These are the real deal. The dead spot that I had in my midrange has now come alive, and it’s great. The front wheel on my XL1200C gets nice and light every time I crack on the throttle. And the drag pipes I have, which were borderline obnoxiously loud, are still plenty vocal, with a bit less overall volume. It’s a really nice soundtrack.

    I will try to keep it short lol! On my 2020 Softail Street Bob I’m running a stage 1 with a extreme flow air cleaner from screaming eagle and a 2into1 pipe from Cobra(El Diablo). So far so good, after tuning it and everything dialed in. There was still a little lag or it took an effort to come out the 3000 rpm. So I decided to give the TTI’s a shot. Believe it or not this bike pulls now from 1800 till 3000 in such an effortless manners that I was shocked. I am a little bit exaggerating but it felt like adding a low end torque cam. Now the bike is a complete Stage 1 in my opinion. Pulls hard from 0-120. Any gear, any speed and any time. This is the best bang for the buck ever!!! I’m not exaggerating!. Most importantly the rideabilitiy improved, I’m barely twisting the throttle to move around during cruising. I highly recommend it to everyone who’s missing that little uumph and get going. It’s been a long review but I wanna to make it clear! Ps. Installation was super easy. No rocket science.

  54. TTI's worth a try 0 people found this helpful
    Quality

    Value

    Bought a pair of TTI 118's, the small ones, to put in Vance & Hines Straight Shots on a 1995 Fatboy. My initial impression is around town I can't really tell any difference but out on the highway my bike feels like acceleration and speeds are more effortless. The build quality of the inserts is excellent, was worth the money to me not to make them myself. Now for the con: For my application the threaded stud wasn't long enough. Tech support was readily available and the solution was to omit the inner nut and install the inserts so the circle was tight against the inner wall of the pipe, no longer centered in the exhaust flow. This way the stud protruded enough to the outside to get a nut on it. A great product would be even better if it had a longer stud available.

    Installed a pair on my ‘03 Night Train running Vance and Hines Original Short Shots with baffles removed. Improved exhaust tone to a deeper rumble, noticeably increased torque and power throughout all RPM range, and almost completely eliminated decel popping (exhaust backfire). I was skeptical of DK’s claims and several YouTube reviews but decided to try them out before spending big bucks on a new set of pipes and was both pleased and surprised with the results. Definitely recommend this product. Make sure you contact DK to get the right inserts for your application. LOUD PIPES SAVE LIVES!
