    Stage I
FatShotz 2-Into-2 Slip-On Mufflers is rated 4.1 out of 5 by 7.
Rated 5 out of 5 by from This product works! I installed these on my otherwise stock 2014 Road King. The tone of the bike is now deeper and has more growl. However the best part is the performance boost these gave the bike. I had stock pipes on the bike and I have to admit that trying to get the 800 plus pounds of my Road King moving was not the best part of riding the bike. With the FatShotz the acceleration is way better and I can get out of the way of the cars behind me at stop lights a lot faster. Also as the Road King is a touring bike and the slightly louder and much deeper sound is not so loud/deep so as to cause ear fatigue during long rides or such as to annoy my neighbors. So if your touring bike is struggling to get moving at stop lights and if you would like smoother acceleration while improving the tone of the bike without breaking the bank, then these would be a choice to consider.

Rated 1 out of 5 by from Sound and performance were good but these mufflers are already discoloring with less than 500 miles on them. I had these put on my 2015 RGU CVO a couple of months ago and have put less than 500 miles on them, if that (my bike has a total of just 960 miles). I was happy with the sound and performance but very disappointed to see one of the mufflers starting to turn brownish gold where it connects to the stock head pipe. I'd had a set of Rinehart 4" slip-ons on my 2012 RGU from day one until I traded the bike for my 2015 back in September 2015. I've split time riding my 2009 RKC so miles have been low. I think I'm going back to Rineharts.

Asked by: dhimsey

Do fewer discs in the endcap change the sound or performance?

I have these on my 2011 FLHX with stage 4 upgrade. Just removed baffles and endcaps for curiousity and was wondering why so many stacked discs in the endcap. What is their purpose?

The FatShotz will work on your trike as long as it's a '10 or later model.

Request P/N for muffler end caps.

Your product pictures show the Fatzhotz exploded parts detail of muffler, disks, end caps and screws. However the muffler installation sheet does'nt show part numbers for the disks, end caps or screws. Also, checking with dealer parts departments they can not provide me with P/N's for these parts. These mufflers are made by Supertrapp so believe the replacement parts are available.
Asked by: Noah
The end caps and hardware on the Fatshotz aren't actually sold separately. Sorry Noah.
