Still tweaking my '14 Lowrider...and this will improve sound, look, and power (with the air breather I also purchased) of the bike.
Richard B on Jun 17, 2016
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.

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.
Scott C on Nov 3, 2015

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
