    Q & A

    Will I have to do anything else to my bike if I put this on? or do these just replace stock with nothing more to do?

    Asked by: bslvrnl

    What performance benefits does this have over stock, does the end cap affect the sound of the pipes loudness, can you operate it without the end cap?

    Asked by: JOLLY
    Hi Jolly! Harley-Davidson manufactured exhaust and/or mufflers do not have a removable baffle. Hope this helps!

    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.
