I have narrowed my exhaust choices down to 2. FMF q4 with head pipe, or barkers full exhaust. I ride some at night and want a somewhat quiet pipe. I have heard sound clips of both, but want to know real life takes on the noise level of these pipes. I know its not going to be factory quiet. How much louder are they, and whichever one I get will have quiet core installed. I am thinking barkers so I can get it, ehs prog, and lid all at my hous at same time. Any opinions???
