    Best sound and looking slip-ons!!!

    Put these on my 23 FXBBS. Awesome sound! Nice deep rumble and way better sounding than stock. Pretty loud for a Slip-on. The stock HD exhaust is so large and heavy compared to these. Super easy install, probably took 30mins.

    GREAT PIPES!! Look great on my 2021 Fat Boy!!!

    Awesome mid-sized pipes! They were easy to install and great looking! What a bite when you get on the exhaust…just what I was looking for, thanks!! Geno
