Don't forget this is a price of one baffle
Dangnabit, forgot this order is for just one baffle. Just got done ordering the 2nd one. Now I've gotta wait some more. I've purchased many V&H products with good results. But come on... just put two baffles in the box and charge what you need.

Install notes to make things easier
Great product, really love the deeper, throaty sound these baffles give my V&H Twin Slash exhaust system on my Vulcan 900 Classic (2 or 3 dB reduction, not nearly as ear-splitting sharp pop).

Some install notes:
1. Pull both rear heat shields off before starting job.
2. Extract stock helical baffles after removing set screw using a pair of needle nose pliers or vise grips on the square backing plate for the set screw.
3. Quiet baffles come with (in this mechanical engineer's humble opinion) far too much fiberglass batting wrap. Here's what I did when it became obvious that these would bind and not fit properly without modification:
A) cut tape on batting, and unroll 6-8" on batting from baffle assembly (there's a fiberglass mesh backing seam that gives a natural margin), cut a remove excess batting material.
B) re-wrap batting tightly, and re-wrap the entire length of fiberglass with a continuous length of clear packing tape (this will burn off in 200-300 miles of normal exhaust temps, no worries).
C) lubricate 1/2 to 2/3 the length of taped batting with silicone lube/vegetable shortening/anything that won't dissolve the tape, leaving the end with the set screw "dry" so you can keep a good grip.
4. instead of the 1.5 hour horror story installs, the baffle will now insert rather easily with a little "with the wrap" twisting and tapping with a dowel and rubber mallet. 2 minutes, tops.
5. Go slow lining up the set screw hole and the square backing plate. Small adjustments with a pair of needle noses on the backing plate. Truthfully this can be the trickiest part. Go slow, be patient and persistent and the threads will grab
6. Thoroughly clean exhaust pipe before reinstalling heat shields. Clean heat shields after installation.
6. Start her up and listen to her new growl! You will smell the tape and lube cooking off as the exhaust stream heats up the assembly. In a couple hundred miles, the tape and lube will be totally burned off and the batting will fully expand, finalizing your awesome new growl that won't cheese off the neighborhood at idle.

Too quiet for me and my Softail Slim
Went from Standard baffles to these... I didn't necessarily want my bike quieter as much as I was hoping to get a deeper tone as some reviews of these led me to believe. After installing I really had to get on the throttle to get any bark out of the pipes... Also at idle it was embarrassingly quiet, yet still louder than stock pipes. I'm not saying these are a bad product, they are quality items and are fairly easy to install. These just were not what I was looking for, if you want a deeper tone, in my opinion, put the money you'd spend on these towards some Big Shots or similar FULL exhaust. If you're looking to quiet down your bike versus the standard baffles which are pretty loud, then by all means these will do it and you'll still be louder than the stock Harley pipes.

Lastly, Don't be misled by videos of the difference in sound, I shot video of the Standard Baffles, then shot video of the Quiet Baffles... they sound almost identical when comparing video to video, but the difference in person/riding is night and day.

Served its purpose
I have the V&H twin slash slip-ons. Loved them at first - gave me butterflies when I first rode away on them, like I had a brand new bike again. However, after a little while, I realized I had a headache and my ears hurt. Couldn't determine at first if it was due to lack of coffee and/or riding in higher elevation, so I gave it a while, but my ears still hurt after riding at high RPM's for a while, like on the highway. I think I already have hearing loss, so I didn't want to make it any worse.
Bought these quiet baffles a while ago, but could not for the life of me get the V&H stock baffles out. Had to take it back to shop and they did it super fast. Bike still sounded good as they drove it around. I certainly do miss the explosion of sound when I'd crank the engine with the V&H stock baffles and the loud but low rumble at red lights. However, my ears thank me because I no longer get headaches or earaches from riding anymore. It's kinda hard to describe the sound of the pipes now - other reviewers described it as low & "throaty," I guess that's accurate. Sometimes I also think it sounds like the classic motorcycle sound I imagined in my head when I'd pretend to ride an imaginary motorcycle when I was kid.
Anyway, overall I wish the bike retained the same loud low rumble at idle, but it still sounds good & it's a trade-off I'll gladly accept to keep my ears healthy.

Now I can hear!
When I installed the Vance and Hines staggered slashed pipes, they were really loud , especially on the top end and raspy. After putting nt the quiet baffles, which was no small feat, I follow the video online and wrapped them with some small gauge wire and they slid right in. Now the bike has that deep bass sound without the extra raspy calamity on top end. Very satisfied.

Does what its supposed to.
These come labeled as "Mamba" but the barcode says Vance and Hines, they are sold each so you need to buy more then 1 if you plan on doing more then 1.
Installing it is impossible to get them to fit without some modification, mine went smooth and quick. I just used what another review said to do. Unravel the insulation around the baffle, cut off about 6 inches of it, rewrap it as tight as possible with packing tape and use a little lubrication (I actually used a very very small amount of vegetable oil) line up the screw hole before you get the baffle all the way in makes it real easy, couple taps with a rubber mallet and its over.
Starting the bike it makes a huge difference, before my ears would ring when I was done riding, it has a distinctive "Harley" sound still and after I completed my stage 1 it is absolutely perfect in what I was trying to achieve.

Can be a pain, but worth it.
There isn't a lot to review in something like this but if you're on this page, its because your V&H included baffles are just too loud. The installation was a pain, I had very low miles on the pipes but just pulling out the stock baffles was a small chore. Getting these to just "slip in" is a joke. I've seen a few videos where some slip in and I'm convinced their pipes are probably 3" in diameter, the slash staggered exhaust is closer to 2 5/8" and pushing these in, they like to bunch up. You can fix the bunching with some 20-24ga wire and a little more tape, but plan on spending some time slowing wiggling these in and making sure they dont bunch up too much. I'd say wear glove, because the fiberglass is rough.
Overall, this did what I needed. I was at over 100db just at idle and now I'm between 87-93db and its tolerable. If you like it louder than that, you're on the wrong page!
I am running a 2014 VN900 custom with twin slash staggered:

Perfect solution, problem solved!
I bought the Vance & Hines 3" Round Twin Slash Slip-on Mufflers, Screaming Eagle Stage Air Filter & V&H Fuel Pack FP3 Auto Tuner for my 2015 Harley 48. Everything worked great, the 48 was no longer choking for air. The bike upgrade worked as planned except that the V&H slip-ons had the standard" straight-through" baffle which was much louder than I expected. I liked it for a while, then realized, my neighbors - didn't so much and I was increasingly aware that the bike was simply too loud. I ordered and installed these baffles and it sounds GREAT!! Bike breathes well,with the same deep growl Harley tone, just a few decibels lower. Easy to install (with a little muscle and patience). Loving the ride even more now! Problem Solved!! Would highly recommend!

I can hear again
VBH1 is correct the baffle is not the one in the picture but it works. I could not imagine all the other reviews were correct on how hard the baffles are to change and I was right but not the way I wanted. These things are a royal pain in the rear to change. The fiberglass insulation wants to bunch up even when using wire like others suggested. I also had a tough time getting the original baffle out. If you watch the Vance & Hines video showing the baffle change out they make it look easy but these thing do not slide in and out of the mufflers at all. I had to beat the old baffles out and use a rubber mallet to get the new one back in. I do like the tone of the bike after the change it seems deeper and going down the highway the volume is not overwhelming as it was with the original baffles. I also noticed the bike ran better and did not backfire near as bad as it did with the original baffles. Overall I think this was a good choice because I could not hear with my Uclear due to the volume of the original baffles.

My installation 2 cents
These baffles come wrapped in a plastic wrap. I read some installation tips before installing and there are a variety of installation methods out there. I shoved in one them with the wrapping in the pipe. (less than a minute) The other one I removed the plastic wrap and it gave me a hard time going into the pipe. I ended up wrapping it with some thread and it took about 15 minutes to install it. I've been riding the bike for over 150 miles now and only in the first few minutes I smelled the burnt plastic. So I suggest keep it wrapped and install it as is. In terms of sound, is a little bit quieter than standard especially during idle. But it has a deeper sound which I love because I'm a bass player :)
