I had them on a 14 limited I really like there system great company. Fit and finish very good . But so far I decated the stock head pipe on the trike. Just came back from NC trike ran great . That got rid of most of the heat issue
they look true dual but there not, i have theses pipes and they really help cool down the heat, and brought my cobra slipons to life on my FLRT, here is a read on them that will help explain, a lot better then what i can do on your crossover question. http://www.revzilla.com/motorcycle/c...ring-2010-2015
