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.

Good buy. 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. August 26, 2015
Didn't fit. 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 July 24, 2015
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. July 6, 2015
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. June 1, 2015
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. April 7, 2015
reduced rumble but still throaty I bought V&H slash-cut mufflers for my Harley Breakout and they were a little too loud for me. I purchased the V&H quiet baffles and they reduced the loudness without taking away the rumble. The V&H mufflers and quiet baffles are WAY better than the original Harley exhaust mufflers.

Bike runs better but doesn't sound as good! I put on a screamin eagle air intake, and vance and hines 3" twin slash slip-ons. I also bought the FP3 Vance and Hines Fuelpak 3 to remap the engine. The bike sounded great with the standard baffles. A little loud for neighbors but I liked it. It did seem to run somewhat sluggish on the low RPMs. I ordered the quiet baffles. What a pain to install! But, I got them in, remapped the engine for the quiet baffles. It runs much better than with standard baffles. Very responsive both low and high RPMs. It is slightly better than stock sound, I don't need ear plugs any more and I'm not rattling the neighbors house. One suggestion. They need to improve how they hold the insulation on the baffle to make install easier! January 19, 2015

bradley p: I needed it quieter lol Oct 23, 2014
james g: I took my stock baffles out because I wanted more sound and open exhaust is just too loud and didn't want to buy a full exhaust system for just a little more sound so these should be what I'm looking for I hope if not may end up buying slip ons. Jun 26, 2014
brice h: for the wifes bike and she wanted it a little quieter and it adds a little back pressure Jun 6, 2014
Craig B: I wanted to tone down the rappy sound of the Vance & Hines Twin Slash Staggered pipes. May 4, 2014
Jimmy W: The Twin Slash Slip Ons are one way to go to get a Harley sound out of your bike without breaking the bank. However with the Standard baffles they are a little raspy. The Quiet Baffles are still plenty "Harley" loud, take out the Rasp that the Standard baffles have and make it a deeper tone. Just what the doctor ordered. Apr 25, 2014
gene s: Slip on mufflers are too loud by themselves even though they do sound good. Don't need to give the thieving state of California any more of my money with a noise ticket. Apr 11, 2014
John M: The baffles that came with the pipes are a little too loud and the sound is kind of "rappy." Apr 3, 2014
Brian S: Use these inserts to make the Twin Slash a bit quieter. Just be sure to order (2). They are sold each, not as a pair. Dec 5, 2013
Donn W: Stock baffles on the slash slip-ons were a little to loud. These are just right! Oct 28, 2013
