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
from too loud to just right Purchased these for my Vance and Hines twin slash staggard pipes to quiet them down some. Once installed these quiet baffles took the noise from overly loud and raspy to a deep and bearable loud sound. December 29, 2014

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
