I ran a NISMO OEM Cat-back on my base 370 for a few years. I had the entire system though. The NISMO exhaust has a little more growl, which is slightly noticable at start up and under WOT. It has no drone and really isn't noticable under normal driving conditions. The entire system breathes a little more freely then the base exhaust. Because if which, Nissan claims it is responsible for half of the additional HP the NISMO produces (approx. 8hp). I don't know how much of a difference this will make without the rest of the CBE though.
