    Stage I
Shorty Dual Slip-On Mufflers is rated 3.8 out of 5 by 4.
Rated 2 out of 5 by from Not worth the money If you are looking for a loud exhaust this is not for you. A lot of money for a little bit of noise. Not loud enough to justify changing stock mufflers.

Rated 4 out of 5 by from sound and look fit the dyna like a glove Won't make the neighbors mad, but they will know you ride a hog. Easy to install your self, dealership wanted 80$ for 2 hours labor, took me and a friend 20 minutes. 9/16 and 1\2 deep sockets, a bucket to sit on and the oldies on the radio, you'll know it was done right and save $$$.

Rated 4 out of 5 by from '13 FXDC SE Slip-on Slash cuts These slip-ons are very well made with excellent heavy chrome plating. They live up to the high H-D quality standards and give a very pleasing sound with out making the neighbors angry. Only grumble - if they were only one "shade" louder they would be 5 star perfect. The baffles are held in place with Torx Security screws and can be rider serviced.

Will I need to recalibrate the ECM?

Will the use of this set of Screaming Eagle Pipes on my 2013 Street Bob require recalibration of the ECM? Will continue to use the stock air cleaner.
Asked by: Gary2013
Hello Gary2013, You will not need to recalibrate you ECM for these mufflers. The stock ECM calibration will work with these. Thank You!
