Vance Hines Quiet Baffle For Fishtail and 3 Round Twin Slash Slip-On Mufflers
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.

I bought a pair of 3 in VH slip on for my stock 15 Street Bob and while I like the sound, it was so loud at high rpms that it made it exhausting to drive. So, I ordered a pair of these baffles... and rcvd them today.
- The ones i received do not look exactly the photo...the fiberglass is far wider than the image shown and far winder than what could be compressed. I tried for hours. I wrapped then whole area super right with tape, and theres NO way it would fit. I tried everything and eventually gave up and put my stock pipes on.. thats too bad, cause I really wanted this to work

Hard to get baffle in the pipe
This baffle produced the sound I was looking for in my Heritage Softail. It was very difficult getting into the pipe due to the fiberglass wrapping. I would recommend you take your pipes off of the bike prior to installation.

Not easy to insert
Well, this should not be too hard to install but in my case it was.
1) The fiberglass around the baffle is wider than the actual muffler, making it difficult to insert nicely all the way in. They should have come up with a way that when you insert the baffle there is not obstruction and once the fiberglass gets hot it then expand inside the muffler. They put some clear tape around the fiberglass but it was not all the way around and it was not compressed either. On one of them I had to remove the whole thing once I had it 3/4 of the way in, it was insane. After trying the second time I was able to manage but still was not fun.
I have seen other companies doing a better job when it comes to quiet baffles.
