My 2014 Street Glide Special with decat head pipe & FP3. Can you recommend these or is it better to have cat with them? If not which baffle size?

Thanks,

 

SB2 baffles are only for use with stock head pipes with a catalytic convertor which is all touring 2010-2015. If you have aftermarket headpipes we recommend all baffle sizes. The larger the baffle, the louder and deeper it will sound. Most people I've talked with like the 2.25" baffles with open headers.
