Will this slip on fit the 2016 Low Rider S with no problem? If so, will ANY pipe/slip on that will fit 2016 Low Rider also fit the "S" model?

Asked by: superslomo
Hi Superslomo, No, this Nightstick 2-into-1 Slip-On Muffler will not fit a 2016 FXDLS. One reason the slip on mufflers for a 2016 FXDL are not compatible with a 2016 FXDLS is because the 2016 FXDL has 1 muffler, while the FXDLS has 2 mufflers. Thank you for your question.
