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 1991-2016 4.8 5 5 5
Low Growl Had these installed with on a 2015 H-D Street Bob and could not be happier with the low end growl and overall sound of these pipes with a stage 1 air cleaner and remapping. Love the Vance & Hines reputation and quality, couldn't be happier with my V & H setup. July 13, 2015
Tone Tone Tone Be warned, the slip-ons come with baffles pre-installed from the factory. One hex screw stands between you and a throaty exhaust note that has gotten me more compliments than a southern belle at the ball in the middle of shore leave. That's the difference between sounding like a Dodge RAM truck and a true Harley. These are fantastic, the tone is completely different from the Straight Shots I had. Installation is easy, as long as you can read, follow directions, and turn a wrench. The chrome is beautiful and compliments the factory chrome heat shields. June 27, 2015
Excellent sound and performance Fast shipping, great packing and the product is awesome. May 25, 2015
Great sound from these slip ons Can't go wrong with Vance & Hines slip ons. They have an awesome sound and a clean look. March 24, 2014
Now my Harley SOUNDS like a Harley So Glad I bought these Slip Ons. Not only did it ditch the Catalytic Converter, which now runs WAY cooler, no more leg melt. But the SOUND, Dat's wut I'm tawkin bout. Sounds way better, and ... like Harley Super easy to put on well. Best money I've spent on anything in a long time. Highly Recommend April 15, 2013

Michael L: i have a set on my sporty and it looks great and sounds awesome! i get a lot of complements. Sep 28, 2015
Lawrence H: You had the exhaust I was looking for and no one else did for my new 2015 Harley Street Bob.
Sep 20, 2015
Richard H: should improve sound with out ECU down loads needed, and a clean look Apr 24, 2015
Claylon S: Good price, hope it sounds good as it looks Mar 17, 2015
David P: I had these on until I could afford RSD slant 2-1 for my 2014 dyna. They are AWESOME. Finally, it sounds like a Harley. Aggressive, deep note. If you wanna upgrade your stock pipes in a massive way but you don't have the bucks, this is the best option in my book. After I got them I didn't feel like I even needed to ever change my exhaust! But I did anyway as soon as I had the money because I'm obsessive like that. :) Jul 1, 2014
A shopper asked: I have a 2014 Dyna Low Rider. The stock pipes are a 2 into 1 set up currenlty. In order to use these slip ons will I have to buy additional hardware or will the hardware that comes with the set have everything I need? Aug 21, 2014

Russ V: The V&H slip-ons alone didn't require adding a tuner to remap the ECU. I put them on and the bike runs fine. If you replace the stock air filter with a performance one you'll have to add a tuner. The V&H Fulepak is plug and play and doesn't require dynoing. Other models offer more parameters that can be adjusted, but require the bike to be dynoed. Dec 15, 2013

Mark J: Yes, I would. Also, no matter who does the install, make sure to LOC-TITE the bolt that mounts to the exhaust bracket at the trans. Mine was not and it backed all the way out. Still waiting for a replacement bolt....... :(

Also, the stage one download is perfect for these slipons.

Piotr M: Not realy. From that what i read you doest have to.
Air flow didn't change a lot because you have 2 1 2 pipes. I didn't remap my. My mpg went down.

Brian S: Remapping should not be required if all you are doing is changing to the twin slash. If however you also change the intake- then you will need a remap. Dec 14, 2013

Donn W: They came with all the necessary mounting hardware. It's a little more involved than bolting into welded mounts on stock muffler, but not at all difficult. Entire swap took me about 2 1/2 hours. Guessing it should be same for your Dyna. Nov 1, 2013
