I think i wanna purchase an Apex N1 catback system, theres only one problem. Where can I buy one at, all of the online vendors i have looked at dont carry the system. Another question is, i would like to know before i buy it if the piping is 2.25 or 2.5 and if the midpipe comes with a resonator. Because i would like it without one. I guess i have one more question how does the sound compare to all the other exhausts one hte market like; Stromung, Brullen, Greddy etc.
