I have an o8 flstc anniv. edition and was looking at getting the bub 7s. Since my headers have a hidden crossover I am torn between getting the bub 7 slip-ons or the bub 7 2 into 1. I have not been able to hear anyone locally that has either. I am more interested in sound. I know the 2-1 should give better performance but since I already have the crossover will it make that much difference? Low deep rumble is what I am hoping for as my stock pipes have little sound to them. I already have a S/E stage 1 A/C and a PCIII installed. One last thing is I am not sure how the 2-1 will look on an anniv. edition FLSTC. Suggestions please
