Vance & Hines Quiet Baffle For Fishtail And 3 Round Twin Slash Slip-On Mufflers 4.3 5 24 24
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! August 16, 2016
Noticable Difference Installed these from the standard baffle. The sound with these installed is noticeably quieter than the standard baffle. My ears no longer ring from cruising around, which achieved my goal. The bike no longer sounds mean, but my ears and my neighbors are happier. The install went pretty well but I did cut about 6 inches of the wrap off to even the thickness. You definitely need to wear gloves as you will create a lot of very fine glass filaments from inserting the wrapped baffle. An improvement would be to have a wire or something to hold the wrap from sliding down when inserted. July 5, 2016
XL1200 Harley now sounds great The pipes I had were just a little too loud for me. was waking up the neighbor's dogs early in the morning. Now I don't worry about warming up the bike before I take off. Sooo much better, but still with the Harley sound! June 21, 2016
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. May 31, 2016
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: http://www.revzilla.com/motorcycle/vance-hines-twin-slash-staggered-exhaust-kawasaki-vulcan-vn900-2006-2015#reviews_tab April 23, 2016
Awesome 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!! January 22, 2016
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. December 6, 2015
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.
