Vance & Hines 3" Round Twin Slash Slip On Mufflers For Harley Dyna

One of the best ways to quickly and inexpensively customize your Harley is to add a set of slip-on mufflers. With the Twin Slash 3-inch slip-ons, you will get the benefit of increased performance and the bellowing, throaty growl of a Vance & Hines exhaust. In addition to the performance and sound, V&H fashioned a stylish look that's blue proof thanks to full-coverage heat shields over the muffler bodies. Twin Slash slip-ons come with standard louvered core baffles.


  • 2.5" round muffler bodies shielded by 3" full-coverage heat shields
  • Signature twin-slash end treatment
  • Optional Quiet Baffle and Competition Baffle (sold separately)
  • Sold as a pair
  • Made in the USA

Note: Photos are shown with OEM accessory head pipe heat shields for reference only - shields for the head pipes are not included with the mufflers.

Vance & Hines 3 Round Twin Slash Slip-On Mufflers For Harley Dyna 2008-2016 5 5 20 20
Big Difference Definitely a noticeable difference in performance and sound. Super easy to install on my 2014 Seventy-Two and looks amazing too! You might want to purchase an auto tuner with this purchase. I got the V&H Fuelpak FP3. July 13, 2016
Perfect product I just got these today and installed them on my 2015 FXDWG only took about an hour to install and Man do they sound GREAT!!! Great product and only a 1 Beard install. May 11, 2016
Didn't know what I was missing I purchased my wide glide last month when the riding weather was non-existent in VT. Every once in a while I would run out to the garage and fire it up just to listen to it. It kept me happy for the time being. Then I put these pipes on it. It became a completely different animal! These pipes sound great and were super easy to put on! They still pop every now and then on the overrun so a re-flash might be in my future but nothing I can't live with. Now it sounds like a real Harley! May 3, 2016
This did the Trick! I ordered the Vance & Hines to replace my stock FXDF mufflers on the recommendation from a friend who already has them on his Road Glide. Like some of the others have mentioned, NOW IT SOUNDS LIKE A HARLEY! The instructions were a little lacking, but enough to get the job done. The whole replacement process took just under an hours with basic toolsl. Getting the stock slip on's off were a pain, but they eventually came off. Lower resonance, louder, but not obnoxiously loud. They do turn heads! Thanks Revzilla, and Lemmy for his videos! February 28, 2016
Exactly the tone and noise level I was looking for! This is my second set of slip-ons for my 2015 FXDWG. I tried a cheaper option which were little better than head pipe extensions and sounded like I was being chased by machine gun fire. These are far more robust and provide outstanding deep bass tone. Decibel for decibel, these are only slightly louder than the Screamin' Eagle option for the Dynas. I attribute that to the fact that the SEs are more mid-tone. Bass sound travels further than higher tones, so these do have a completely different (in my opinion, better) presence than the SEs. These are significantly louder than the stock horror that comes with the bike by a good 10-12 decibels. Stock runs around 75 dB, these are around 87 dB- 90 dB at idle based on my totally janky iPhone decibel meter. If that sounds like a bit much for you, I'd still recommend these, but pick up the quiet baffle option for them. These settle down nicely at speed, I can hear them, but they're certainly not overwhelming at all. For example you could easily hear a radio setup if you had such a thing on your bike. They have a lovely, deep roar when you spin up the throttle, then settle into a low rumble as you boogie along. A major advantage is that I can now easily tell where I am on my RPM curve, whereas with the stock pipes, I was constantly looking down at my gauge because I could barely hear the engine. As Harley pipes go, these are not terribly obnoxious, but people will definitely know you're around, which is exactly what I was looking for. Install was simple, which was good because the instructions were a bit lacking. Since I'd installed slip-ons before, this was very straight-forward. Just had to add a small metal adapter to the frame, then installed the heat shields to each muffler and on they went. They slipped right on to the head pipes without any issues. Total setup time was about 45 minutes after I got out all the tools. Much of that was wiggling off the old mufflers. I bought these with the intent of also picking up the V&H FP3 fuel tuner, but I thought I'd see how much decel pop I was going to get before putting out the moolah for a fuel controller. I had already had my EFI map flashed by the Harley dealership to a richer setting after I put on a heavy breather, but these guys are popping pretty bad on the hills. Unless that doesn't bug you, you'll need to either get a fuel controller of some stripe, or have your EFI reset at a shop. No big deal, as that's likely true for any after-market slip-ons.

Excellent sounds like a Harley! Took about an hour to install, sounds amazing! Still can't get over how great it sounds. Bikes a head turner now. July 22, 2015
Definitely worth the money. I could not believe that I one got someone on the phone on a Sunday much less on Sunday July the fifth. Yes Revzilla answered their phone on a holiday weekend and were extremely helpful. Surprise two came when I received them the following Tuesday. Yes two days after I ordered them they were on my front porch. Due to a rough work slash weather schedule I was unable to get them on until today. These pipes are what Harley should be installing as factory equipment. Not those things that make your engine sound like a sewing machine. They have a deep rich thunderous tone. I will say if you are looking for that high pitched crack from a straight pipe these are not for you. But if you want that true Harley sound deep roar get them asap. I couldn't be happier with the service I received or the parts They sent. Great job Revzilla and Vance And Hines. July 11, 2015
a must for your first upgrade. I put these on at 600 miles. I wish I had left the dealership with them on. My 2014 Dyna Fat Bob went from sounding like a sewing machine to a real road beast. The perfect combination of throaty sound and throttle response. Installation was about an hour, most of which was fitting stock Harley clamps on. Plus they are about six inches shorter than stock pipes. Harley-Davidson should be ashamed that their stock bikes don't sound this good. I've already ordered the Vance and Hines VO2 Duke and cannot wait to see the difference. I would recommend these slipons to anyone as the quality is of the highest quality. June 23, 2015
