Vance Hines 3 Round Twin Slash Slip-On Mufflers For Harley Dyna 2008-2016
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.

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.

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.

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.

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.
