Looking to add a bit more sound to my 2017 6.7, was looking at the flo pro dpf back kit but the guys at flo pro said that it would not make any sound difference, anyone got any of these kit installed and have you noticed any difference in sound???
No difference in sound with DPF back from any of the manufacturers.
Banks makes the slickest DPF back with their cool cuff, but no sound increase. You'll have to go outlaw if you want noise.
