Awesome upgrade for my 15 Low Rider
Although I didn't buy the parts from Revzilla, I do own this as i got a good deal right after I bought the bike elsewhere. This is an exceptionally well built product. Vance and hines build quality all they way! The pipe took me about 20 minutes to pull the old one off, put the new on and clean it off. Instantly on firing it up, it sounded like what i always thought a harley should sound like. It has a good deep low rumble at idle and revving it up sounds fantastic. It is not obnoxious loud, but a good Harley Rumble Noise!!

Highly Recommend it. Fit well on my 2015 Low rider FXDL.

I also did a Kuryakyn High Flow air cleaner and finished it off by mapping the bike with a Fuelpak FP3 from Vance and hines. All said and done, i think this combination of upgrades is the best upgrade and bang for the money right now for this bike.

I have bought other parts from Revzilla and would recommend buying from them. Always had good experience dealing with them.

Great muffler
Everything was in the box. Fit was perfect, finish was great and sound was much improved over stock and still no so loud as to be offensive.

Good Rumble but not loud enough for me
I bought this from revzilla. Service and shipping great! Took no time to install. It is a vast improvment over stock. However, this just isnt loud enough for me. I even took the baffle out and still not loud enough.

Vance Hines Twin Slash 2-Into-1 Slip-On Muffler For Harley Dyna 2012-2016
This item in addition to the air cleaner that was installed with it has made a huge increase in performance (after mapping of course). However, if you are looking for a loud rumble from your pipes, do not choose this item. Spend the money on the pipes. This item is a muffler after all.

big rumble, small bucks
Revzila got this shipped to me in 48 hour. Nice! The hardest part of the installation was getting my old pipe off. New pipe is much deeper and throatier, with a terrific roar when the engine is pulling hard. Much improved over the stock pipe. Definitely get some decel popping, but I can live with it - it is minimal. Good deal!

Vance Hines Muffler
Very nice muffler sound a deeper tone and won't dis-color my chrome as the night-stick from Harley. Like it very much looks great fit just a little longer over my hard bag. Easy to install about 20 minute ready to ride. Make sure you clean the grease and finger print off the muffler before start your bike.

Vance & Hines product, looks, and sound,. Installation was very easy even though I only could use one hand at the time.
Took me about 45 minutes from beginning to end to complete.

Several suggestions from Mitch at Revzilla. My wife picked the Vance and Hines. This is for her bike.

hopefully a better sound
Barry E on Apr 25, 2016
I wanted to replace the factory HD 2 into 1 tailpipe with something a little more aggressive for sound and performance. I wish it was a little louder, but really like the appearance.

will I need to re map my engine after I put these slip on mufflers on my Dyna Switchback 2014 ?
A shopper on Apr 22, 2015
BEST ANSWER: I would but technically they say it isn't needed. I had a lot of popping when decelerating.
if i install the slip on , on my 2012 harley davidson switchback do i need it retuned , oxcegen censor?
A shopper on Apr 24, 2014
BEST ANSWER: Only retune it if you want good performance
How far back does this extend on a 2015 Lowrider FXDL? The stock pipe ends at about the center of the rear tire. The pic shows a switchback and extends way past the rear tire.
ANDREW N on Sep 13, 2015
BEST ANSWER: The slip-one are just a little bit longer. Maybe six or eight inches. They are just about even with where the tire meets the wheel.
Ive got 204 dyna low rider, vance & hines customer service guy told me this would work on my low rider, while others say they are having issues with this? any input, I dont know what to get.
A shopper on Jul 11, 2014
BEST ANSWER: I have a 2014 FXDL too and I'm thinking of buying this and installing it anyway. I mean, V&H site says it'll fit so I'm figuring it should be good.
I have a2016 dnya low rider fxdl will twin slash 2-Into-1 Slip-On system fit?
A shopper on Mar 18, 2017
BEST ANSWER: Yes it will. It fits like a glove. It was just too quiet for me. I'm getting ready to upgrade the exhaust again.
do I need to recalibrate my engine if I just get twin slash slip ons for my dyna switchback fld 2013?
A shopper on Jan 19, 2015
BEST ANSWER: If you're just going to install the slip on with a stock air cleaner, you should be fine... Just keep in mind that your bike is tuned on the lean side from the factory...FYI the catalytic converter is in your head pipe... So you will gain some sound but, not as much with a different head pipe as say an off road or cat-less head pipe.. Wink wink
