I bought my Sportster without baffles, being my first Sportster I didn't know any better and almost lost my hearing. I had to do a minor modification to make them fit but the bike sounds so much better and greatly improved my overall love with the bike. Worth every penny!!

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.

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.

Not the sound I was looking for
I bought the slip ons for my sportster. At first I thought they were too loud, so i bought the Quiet Baffle. However after a few rides I thought they sounded too muffled, much quieter but lost the aggression I was looking for. I have removed them and gone back to the original baffles. Maybe i will try a modification of the quiet baffle this winter, but i didn't really like the sound. I just wanted to knock down the volume about 25% but i felt it changed the overall sound and volume too much.

Good Product To Keep The Peace.
Purchased V&H Twin Slash slip ons for my Sporty about a month ago. Awesome pipes but loud. Not that I didn't like the sound, I loved it! But my neighbors didn't so to keep the peace I bought these quiet baffles. I read some reviews prior to purchase and based on those I expected the install to be a pain but that wasn't the case. I did remove about 3" of the "fiberglass" (it is actually a ceramic product, not fiberglass at all), re-taped it around the baffle and installed. The fit was snug but not difficult. The sound is definitely quieter than the standard baffle, less edgy but still throaty. Somewhere between stock and the standard that comes with the pipes. Performance is still better than stock too. Don't forget to remap fuel for the new baffle!

Not to quiet
Baffles were easy to install. I removed some of the outer wrap to ease installation . The stock baffles in the twin slash pipes were a little bit loud so I tried the quiet baffles. The decibel level is good but the sound takes a little time to acquire a taste for.

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.

Bought a set of V&H pipes that turned out a little loud for my tastes. These quiet baffles worked exactly as promised. They were a little tight to install at first, but I removed a small amount of packing and wrapped the remainder with some wire, and they went in a lot easier.
I gave them 4 stars only because of the slight modifying I needed to do.
I would highly recommend this product.
