Torque Cones Harley Davidson Softail Fatboy

[@cedler426]

I think Thunder Torques are the way to go. Harley recommends them if going without baffles

[@Mikeityourself]

Thanks for the support, I'll check them out.

[@tellawcaster]

Thunder torques are brilliant. You don’t have to guess, you’ll feel it immediately.

[@eccentricsmithy2746]

Anything Harley recommends is a gimmick. Cones are better than anything place in the last 2 foot of exhaust pipe.

[@tonyezolt4560]

@@tellawcaster 100% spot on. DK took the old "lollypop" trick to another level. You feel it immediately.

[@clivejames9268]

reversion cones are to stop the shock wave re,entering the exhaust tract , they are used when higher duration cams are installed. the shock wave can cause the incoming charge to be blown back into the inlet track, because of the greater cam overlap the exhaust valve is still open when the the inlet valve is opening. stage 1 cams standard aplication stage 2 cams ehaust ignition carb upgrads stage 3 cams all the above plus port and inlet valve changes, you wuold not really notice a big change unless you are running high lift longer duration cams good hunting!!!!

[@Mikeityourself]

Thats some good feedback. Thank you for your support and watching. I appreciate folks who can share their knowledge and experience.

[@jorgedelangelgarcia6360]

Can I install them on the exhausts of a 1200, carbureted, 2005? This one has the factory exhausts. Is it recommended?

[@Mikeityourself]

I wouldt recommend just on my personal experience but they are cheap enough to try them and if you don't like them then the money doesn't sting as bad. Here is a link to jp cycles for your model if I have it right. Always check the fitment section. www.jpcycles.com/motorcycle-parts/2005-harley-davidson-sportster-custom-xl1200c?view_all=&page=1&limit=96&has_loyalty_discount=false&is_new=false&is_sale=false&is_made_in_usa=false&is_holiday=false&is_blemished=false&sort=featured&fit=&query=Torque+cones

[@Bkamaclean]

Good review...I always wondered if they made a noticeable difference...I probably won't bother with them after watching your review.

[@Mikeityourself]

Thanks for watching. I was a bit let down when I ran them, was really hoping to see something but no dice. Glad I could help.

[@steveadams5190]

Tried them on my Evo, no change. Tried a ser on my Shovelhead and did notice a difference. 🤷🏼‍♂️

[@Mikeityourself]

Thats pretty wild. The good thing is they are cheap enough to give'em a run and not worry if they dont. Thanks for watching.

[@Nine_883]

Snake oil, but they might say it increases exhaust velocity clearing the cylinder of non combustible gasses faster and getting a better burn and run a little bit cooler.

[@Mikeityourself]

Total snake oil. I couldn't find and hard data to support performance, seemed to always be opinions.

[@ericberg7364]

Thanks for an honest review.

[@Mikeityourself]

Glad it was helpful!

"Torque Cones" are actually a gimmick for those that cannot "tune" a bike, or doesn’t understand engines and how some modifications work... See, most guys pull their factory exhaust off, and put on drag pipes on, and then they either don’t understand or cannot comprehend why it “Feels” like their bike lost “Low end torque” and it may have, at specific RPM…But let’s see why… Firstly, most bikes, (at least prior to Exhaust Catalysts) are very lean for emissions reasons… So when you “uncorked” the exhaust, you’re allowing better exhaust scavenging (the hot exhaust pulse actually “sucks” on the intake, as usually for a few crankshaft degrees while both valves are open “overlap”), much like a slight cam change…and now on the intake side you’re not allowing enough fuel to go with the bigger/longer duration gulp of air the engine is getting, (carburetors and open loop EFI are susceptible to this issue, closed loop EFI with learning fuel trims can usually relearn and fix this), and depending on the overlap of the cam (read High RPM race cam), maybe some of that charge could even be dumped into the exhaust, but on a race engine, who cares? - Lean on fuel = Low Power, need to increase fuel flow “jetting” to match air volume. Secondly, Going back to the science, eliminating the back pressure, you have effectively lengthened the exhaust duration (because the exhaust of the previous cycle is right before the current intake cycle), because the Drag Pipe exhaust gasses move easier, there is less back pressure, which is increasing overlap, cam manufacturers will tell you, more overlap favors a higher RPM torque peak so in theory you have raised the “Torque Peak RPM” of the engine, so it really doesn’t lose torque, it just moves it a little higher in the RPM band…BUT because its more efficient, there is also MORE torque to be had there. So, where you had a PEAK of 100lb-ft at 2000 RPM w/Factory Exhaust, you may now have PEAK of 104lb-ft at 2200 RPM w/Drag Pipes. What torque cones are made to do is give the cylinder that back pressure again, but closer to the head so your bike can be loud! (Using drag pipe as megaphone). But with the back pressure “back” in the exhaust, you are back to 100lb-ft at 2000 RPM and your bike is louder, so it sounds cooler, and now you wont need to “tune” the intake side for the better flow. - Torque Cones make “Drag Pipes” into “All Show and No Go!” I get a lot of people that put Drag Pipes on their bikes, and then call and complain their bike runs like crap....Yep....Your Jetting is Off!

[@Mikeityourself]

Thanks for the feedback Mister S. I definitely appreciate the knowledge being shared, feels like its harder to find these days.

[@misters2837]

​@Mike it yourself Yes a lot of people want to just sell you something...I actually work for one of those two companies you listed in the beginning of the video...and yes we sell them...but not all of us are sold on them...LOL

[@Lordleeforfreejones9897]

What a great explanation get in

[@bvonroth]

I’m led to believe they are used when you don’t have baffles as it reduces reversion which kills low down torque, something your baffles were already doing

[@Mikeityourself]

Did some research on that too. For fun I pulled the baffles out and did another run just to see if i noticed a change. Seemed about the same, which does make sense that if I am already used to the baffles providing the reversion then swapping them from the Cones wouldnt be noticeable for me. You make a good point. Appreciate the feedback.

[@BlackMountainCycles]

@@Mikeityourself I actually emailed DK Customs about this question when putting on my new exhaust, and their dyno charts showed no improvement using the torque cones with baffles.

[@tomconte1765]

@@Mikeityourself Baffles create back pressure. Torque cones reduce reversion. They achieve different results, although small. Probably not very noticeable unless, as you stated, dyno tested. 1 or 2 HP on a 650lb bike with a 180lb rider won't be easily noticed.

[@Sk8ntats]

Hi Mike, can you tell me where you purchased those exhaust pipes and heat shields? They look great and sound great. They also look like they would accommodate having a fold out kicker arm. Great video! Thanks

[@Mikeityourself]

Whats up Clutch, hope all is good. Pipes were already on the bike when i got it. They seemed to be your standard drag pipe, they had no brand so mine were probably on the cheaper end. Heat shields were an Amazon buy. www.amazon.com/gp/product/B08M3RX3LK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

How did you retune the bike after you discovered the bike needed further work?

[@Mikeityourself]

@@kraptastic333 it eventually was taken to a Dyno for tuning

[@gregt4270]

I tried these on my EVO and didn't notice any difference. There is no substitute for a quality exhaust system.

[@Mikeityourself]

Completely agree

[@chrisl.7345]

It was a big thing back in the late 90’ s until everyone found out they were useless,..nothing can beat a “step weld” 2-1 exhaust pipe with cone shaped megaphone muffler like the Bassani or Diablo systems 👍🏻☠️🛠

[@Mikeityourself]

fads, they come and go right. Thanks for you support.

[@kennyh5083]

They were used on high performance Chevy V8's and they were NOT useless Homie! They just need to be used with other equipment, (duh) like headers, cams, intakes etc. Hot Rod magazine used them in their 26mpg 375 HP small block engine! also used alot in turbos, and in a few other builds as well. They do work amazingly well when used with the right compliments! and it wasn't the 90's it was back in the 70's Homie!

Thanks for watching. Its been some time since I did this video but normally I dont do step by step tutorials. There are many out there but like I said when I did my review, really couldnt tell the difference.

[@SPARTAN-i3r]

So did it help with performance?

Not that I could tell. I was really hoping to notice some type of change but Nada. Thanks for watching and supporting the channel.

[@jimscycleandautotn8508]

any sound change ?

[@Mikeityourself]

I didnt notice any at all. It could have been there but probably would need a DB meter to check. I placed some JP Cycle baffles in and seems to run a little better.

Don't need a dyno, just pull off from a spot to a marker look at your speedo do it 5 times, install the cones do it again note the difference. Too easy.

[@Mikeityourself]

I like it, imma try that on the new project. Thanks for watching.

[@theodavies8754]

Ideally uphill in a built up area.

[@westcoast3595]

Those things started off as anti reversion cones. Then they became torque cones. Not worth the adventure.

[@Jonathan-L]

I think I might give placebo cones a try :)

[@StacySzanyi]

Take the baffles out and u will see the def.

[@Mikeityourself]

I had tried it both ways, just never was able to get the performance I was expecting. Appreciate the feedback. I did find out later that the bike was out of tune.
