I have noe changed my 5" kit from my lbz because i wasn't a big fan of the sound to a cool dual kit with the front pipe too to tell you the truth they sound pretty much exactly the same. The four inch kit may be a tad quieter and lower if your really really paying attention but i think the 5" kit sounds more mean but the four inch may look better dont know what to do??
