Not sure if you're asking about lollipops in general, or the TTI's. As Joe noted below, if you have baffles in the pipes, there is very little to no gain in putting a traditional lollipop in also.

However, with our patented (which V&H can't use) TTI, every single bike that has V&H pipes on them will see a 5-15% increase in low and mid range torque if the TTI's are added, whether they have the baffle or not.

Even though the sound waves are broken up, there are still varying degrees of reversion that rob low & mid range power. TTI's are better at stopping that reversion, while NOT creating power robbing back pressure, than any other design available.

 

So would a guy wanna add these tti's to a set of 39" cholo fishtails on an 03 carbed softail that was tuned with v&h big radius pipes on it? I'm replacing my BR pipes this week and would hate to notice a power drop

 

If your cholos have no baffles, like mine, then yes you should install the thumb screws or perhaps the torque tubes DK offers.

If you have baffles then you don't need thumb screws. Maybe you want the torque tubes you can chat with DK about those.

It's the open pipes that have the reversion problem like you see in the dyno sheet in the first post.

 

Yeah, I have some fishtails on my personal softail. Got a nice bump in the power with the TTI's added to them.

Below are a couple of charts for the Softail that is in the video in post #8 above.

 

Good deal, looks like I will be needing to order a pair of the W158 since the Samsons are a 2 1/4 pipe. Hopefully I will be installing tonight.

Is there a forum member discount?

 

Kevin, how would these compare to something like Big City Thunder's product? That make a stepped down section of pipe. There must be something in the way that the exhaust pulses react to the step down section compared to the lollipop shaped restriction. Not looking for you to bash someone else's product, just trying to understand how the exhaust pulses react to the different approaches of restriction, that's basically what is going on right? Adding some restriction without creating turbulence.

I have a set of VH Big Shot Staggered on my softail, when I look in the end of the pipe there doesn't seem to be much left of the original baffles, they're a little over 3 years old and I've been considering trying some sort of baffle in them for torque, I do love the sound I have now so I wouldn't want that to change much.

 

I listened to the clips but still want to confirm before ordering. I dont want to lose the unbaffled straight pipe sound, I hate the baffle sound. Whats the verdict, will the tti "baffle me"?

 

We periodically run Specials. You can see the current one HERE.


We have dyno'd the TTI's in Big Shots and Short Shots. They do better than any other method...including many variations of lollipops, BCT's and baffles.

The simple reason is that they stop almost all reversion without creating significant power robbing back-pressure. Back pressure fights against the engine producing power, but until the "W" version of the TTI's there was no way anyone was stopping reversion (including any of the stepped systems) without creating power robbing restriction.

The "Cup" on the outside of the TTI stops the energy pulse from traveling back up the pipe when it reverses direction. The opposite side of the cup is rounded, and the wavy part of it speeds up the exhaust gasses without producing significant restriction (back-pressure).

The TTI approaches the challenge of reversion completely differently...and fortunately, more efficiently, by reducing reversion without as much increase in restriction as other strategies.

It will be just a little bit deeper, and 1-2 decibels quieter. Human ear cannot really tell the difference between, say 105 and 103 decibels, but most can hear that it is a bit deeper tone.

 

I just placed an order for the W158. Very curious to see how they work.

 

I can't believe this works.!!!! I proceeded to install these thumb screws just for ***** and giggles. Yes my bike popped bad (notice past tense). So I gave it a shot. My bike no longer pops and I have to say I noticed a change in how the bike is preforming. I took it out after installing and said wow it seems peppier. I noticed at which rpm range. Now when I watched the vid and looked at the Dyno chart I didn't pay attention to the graphs rpm ranges. When I got to my buddies House. I showed him this video. we look at the dyno chart. I said holy **** I didn't notice the charts rpm range. It's the same rpm were I noticed the difference in my bike. 2500-3500 rpm.
Well we then installed them in my buddies bike 103 big radius and he always said he's bike was a dog. Sure as **** he says it not feels like he could break the rear tire loose. His bike still pops but not as aggressive.
My bike now accelerates 65 or so to 80 effortlessly. And also in those 2500-3500 RPM ranges inevery other
