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.

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
If you're keeping stock Harley headers, you need these I ordered these slip ons to replace a set of Cobra slip ons (and black out the bike) and what a difference. The bike has a lot more bark without being obnoxiously loud. I like the stock headers and look of the tommy gun heat shields on my Harley so I didn't go the full system route. The only advantage the previous slip ons had is the ease of installation. These aren't hard to install, they just aren't as intuitive as the Cobra's. I also ordered and installed the competition baffles. April 28, 2015
Great sound and value..... Awesome product, great sound, and some additional performance when paired with a tuner and air cleaner. If you are looking to get around the harley tax without breaking the bank on a full system and the extra's to make the system run right on the bike then this is perfect. Easy install with hand tool and a little know how. December 3, 2014
This product has great sound The product fit my bike 100% ... Highly recommended .. The sound is pretty good and sounds good. November 17, 2014
Vance and Hines Quality Great upgrade from the stock mufflers!! Great sound! September 5, 2014
vance and hines Received slip ons revzilla very fast and will recommend to others.But vance and hines according to picture they have upper heat shields....but nope they dont come with that so they use another black upper heat shield instead screaming eagle. And of coarse harley has them for an additional 230.my suggestion is that vance and hines change the picture or let people no! July 2, 2014

Marty S: I tried to look/listen to lots of videos before purchasing these pipes and due to each recordings mic they were all very different. I have only have a crap cell phone so any recording wouldn't be very good. I can tell you I love these pipes, and when I first installed them and turned on the bike I was smiling ear to ear. They are loud, but not the loudest. Perfect for me. They will cause car alarms to chirp and go off when you pass by and while on the freeway even with a full helmet you can hear a nice rumble.
I have a 2013 dyna superglide and now it sounds like a harley. I had to also add the v/h fuelpak due to decelleration pop, so I also added a v/h air cleaner. All from revzilla, Couldn't be happier with my purchases. There are other slip ons out there, but I decided to go with v/h due to their rep, and their customer service/help is outstanding, as is, Zillas'.

Mark J: No, sorry, no audio or video. I can, however, tell you that with the standard baffles they are LOUD. I had to purchase the "Quiet Baffle" from V&H and it is much nicer now.

A shopper asked: I have a 2012 Fat Bob and I was wondering if I would HAVE to get a fuel pak? or could I just bolt these up and be good to go? I want to get the fuel pak but I want to get the exhaust first. Cant order them at the same time because that's still a lot of $$$$$$. Thanks!!!! Sep 1, 2015

Ronald B: If that's all you are changing you should be good to go. The ECM will adjust to the slight change without the need for a tuner, thanks in part to the 02 sensors in the head pipes. There is a lot of info via a Google search on 07 and later Dynas upgrading to Stage 1 pipes and air cleaners and maintaining the stock map without an issue. I'm not advocating it or discrediting it, just stating the info is there. But, you'll be fine with slip ons and a stock tune.

I have the VH slip ons, competition baffles, S&S air cleaner and FP3 on a 2014 Fat Bob. The FP3 map got rid of 99% of decel pops.
