Look great when installed. Look stock, the sound gives you an outstanding roar.


Sounds mean. Happy with my order


Much Louder than stock. Installed on a 2016 883 Iron and couldn't be happier. If you don't like it loud consider getting the quiet baffles for these as well.


Great pipes and easy to install. A little louder than I expected but I'll see how it goes for a while. I may purchase the quite baffles, maybe.


Love these slip-ons! They look and sound great, and they’re pretty easy to install at home. I would definitely reccomend these to anyone looking for new mufflers


Received exactly what I expected.


when I removed the packaging from the mufflers each muffler had small scratches and small raised bumps on the chrome. my first thought was someone had tried and returned these mufflers. my stock mufflers looked better than the new ones and they are 4 plus years old. since the mufflers had heat shields I decided to proceed. the install went well. I like the sound but they are a lot louder than the stock. I will ride them for awhile to see if I get used to them or maybe go for a different baffle. the low rating is because of the condition of the chrome, I had read of the high quality of vance&hines which i did not receive.


These mufflers sound great on my 2013 Harley Forty Eight. Was torn between getting these or a new full exhaust, decided on these hoping to save money by not needing a FuelPak/remap. Hardest part was getting the old mufflers off, otherwise installation was a breeze (1 hour to 1.5 hours for everything). They sound and look GREAT. People can actually hear me when I'm next to them now. They are plenty loud. Bike runs great (seems to be a little quicker) with these and I have not had to adjust anything. I wrapped my stock exhaust pipes in black and it looks awesome with the black heat shields. Do not hesitate to buy these mufflers as they are plenty loud, sound great, and perform great!


Can't beat V&H build quality. Slip-On's fit my FatBoy Lo perfectly and the sound fantastic. Not too loud even with the stock baffle. Only complaint was how slip-ons mount to stock bracket on bike, too many little nuts and bolts to get it mounted. Don't know if the V&H bracket would be easier but it would be something to look into before purchasing these.


Love the sound of my new Vance & Hines pipes on my 2013 Fatboy Lo
