anyone ever use exhaust cones??????????????
 
I recently heard of these while i was browsing ebay and im wondering if they are as good as the guys said they were...

Torque Cones

Exhaust.....yep
Cones.....yep
Exhaust cones....nope

nightrain116 06-13-2010 08:33 PM

Used them on my nightrain with an S&S 116. Had samson big guns. Used them to get rid of a hiccup on light accel.. but got a hissing noise through the exhaust..... It's always a give and take

bikerlaw 06-13-2010 09:41 PM

I just ordered a set of new drag pipes and torque cone for my Dyna on Friday. I have heard good things about them both in the past and from members on this board. I am also gonna try the lollipops in conjunction with the cones, but I hope to have good results.

im more or less wondering how they would operate with the fuel injection and all

did they help the bike on power/performance? or did you run baffles as well?

I assume this is what he's talking about:

I used em several years ago with a set of samson pipes. I think they were big guns. I couldnt really tell any difference, and I always wondered if the restriction at the head pipe would make it run hotter?

I have a set of torque cones for $15 shipped if anyone wants them. If you are running drag pipes you should run them. I took off my drag pipes, so they are just taking up space. Do they work? Well the point of them is to keep hot exhaust gasses from being sucked back into the exhasut port on drag pipes. They do work.

They are perfect for Drag pipes. I noticed an improvement when I installed a set w/cycle shack drag pipes on my low rider. They mitigate the reversion wave that interferes w/exhaust gases exiting the exhaust port.

BikerV 06-14-2010 08:01 AM

I used them on an 87 Softail. It had the stock 80 inch motor with a mild cam, S&S super-e carb. They helped bottom end power but I also think the 2" exhaust was too big for that set-up. That's probably why the torque cones helped.

Quadancer 06-14-2010 08:40 AM

Oddly, I thought they were required when running straight pipes. We had to use them on the old Triumphs or we lost so much power it was ridiculous.
I can't say for Harley, since I won't run straight pipes any more.

Samson_info 06-14-2010 02:37 PM

Torque cones help a lot with free flowing exhaust to help increase the velocity in the exhaust pipe. Tests have shown using Samson torque cones which are different than others by use of what has been known as an affect that help squeeze the exhaust flow evenly and expelled evenly will increase your torque by 3-5 foot pounds of torque on any engine. This may not be felt by seat of the pants riding but the numbers sure do show on dyno runs. Please be advised the Torque Cones from Samson are a trademark name referring to our CNC machined 300 series stainless steel Torque Cones. Not just a tube that has been stamped to restrict flow. Ours is the one that actually give the best results.

adjustable baffles
 
Do'nt worry about your slip ons with a loud sound. I am actually working on a mechanical system to be fitted inside the open straight tail end of the slip on which can be adjusted before your ride with a hexagon inner key. Changing stepless from the rumble, just loud enough to hear that you ride a Harley till the screaming breast trembling roar of open exhausts. So you can choose for expect less than 480 US per pair. Easily to be mounted by yourself..Testing at this moment, sound level checks in several positions of the mechanism. Soon I will bring these on the market..

I had Sampson Torque cones in my old first gen Big guns.... they did seem to help with backpressure and "smoothing out the torque curve". I didn't notice that mid range drop that I had before installing them. Those old big guns were straight pipes with no baffles - not sure what, if any, benefit they would give if you were running baffles though.

I have Big Guns 3 on my 08 FXDSE2 and am interested in taking out the baffles. If i can stand the loudness can the baffels be reinstalled.Would you run cones with baffles still in

if it was my bike i would run baffles and cones for best performance. your low end and mid range will be at its best with this combination.

umm those are called electric cut outs but you are making manual add in's ?????

bikerlaw 06-17-2010 12:08 AM

Just for the record, I installed my drag pipes today as well as the torque cones. I couldn't be happier. I asked both of the techs at my local shop and they said and it doesn't make a lick of difference if your carbed or fuel injected. They help allot. With me, to the point that the bike actually runs better than it did with the stock exhaust with punched out baffles. Popping and backfiring is reduced as well. Bikes just a whole lot louder.

Quadancer 06-17-2010 07:23 AM

I never believed that the FI could make up for a poor backpressure; it can only control fuel mix.
Now just don't wake up the citizens or we'll all end up riding with stock pipes.

jluvs2ride 06-17-2010 08:07 AM

This from Pipe Dreamz
 
People think straight pipes make
more horsepower. WRONG!

They are under the false impression that if the engine breathes better and gets rid of the unwanted exhaust fumes faster, they will go faster . . . Credit goes to Jerry Branch, the genius of Flowmetrics to understand how back pressure is needed to scavenge the unburned portion of fuel back into the
combustion chamber to create more horsepower.

IT REALLY WORKS!

PROBLEM: Harley riders & custom exhaust pipe manufacturers like PIPE DREAMZ, want the clean, cool looks and hot sound of straight pipes.

SOLUTION: Torque cones, (power cones, torque valves) a small 2” funnel style venturi valve that provides the correct back pressure by creating a tube constricted in the middle and flared on the end. This operates on the principle that the exhaust velocity will increase and it’s back pressure decreases when passing through the torque valve. At low speeds, the taper in the valve increases back pressure resulting in increased low RPM power and torque. At high speeds, the venturi effect created by the torque valve increases exhaust gas velocity. This maximizes engine power by increasing the rate at which the exhaust gases are drawn from the exhaust ports. *

*SIMPLER EXPLANATION: Picture your garden hose in your driveway WITHOUT a nozzle, and the water turned on full blast. As you can see, the water does come out at a strong steady stream.

Now, picture the same water hose with a spray nozzle attached (Venturi Valve). Watch the water blast out with 3 times the pressure! Same exact principal with your exhaust! The average Sportster or Dyna exhaust exits the cylinder in a cyclone circle, hugging the inside of the pipe and reverberating back and forth, up and down the exhaust pipe 6 to 12 times BEFORE EXITING! This clogs the system and actually slows your bike!

Torque cones work best on straight pipes w/out baffles. If you already have baffles, they add backpressure and disrupt the reversion wave. Why would you add torque cones and more backpressure????

bikerlaw 06-17-2010 09:01 AM

Yes, I now totally agree with you. As I mentioned earlier, I just installed a set of drags on my evo. I installed the torque cones and went for a ride. I then installed lollipops. At first I thought I liked it better. But I took them back out and in a couple more times, since it takes maybe 10 seconds and some burnt fingertips. I even tried them at different angles. Like flat, 45ish degrees and so forth. After a bunch of tests, I am now convinced you are exactly correct. Torque cones is all you "need". Now if johnny law, the neighbors or vehicle testing is an issue, then by all means, run the baffles with the cones. But as far as performance, operation, backfiring, decel pops....I am gonna stick with just the cones. At least for now.

There are baffles and there are baffles. Not all equal, and Flowmetrics is a very complicated science. Best thing is to experiment and find where your power is. Erring on the quiet side is usually going to do better, and also keep us from extra legislation due to brain-dead hammerhanders.

You are correct about there being a wide variation in the performance of different baffles.

I had a 94 Low rider w/drag pipes and a CV carb. I had the tune pretty good, but when I added the torque cones there was a noticible improvement so I tweaked the carb a bit more. It ran really good for an 80ci carburated Evo.

I'm going to install true dual headers (2-2) on my 09 Ultra next week. Pretty much everyone told me that by doing it, I'll lose a few HP and ft/lbs at low rpm compared to the stock 2-1-2 headers.
Would torque cones help regain the torque I'll lose?
