I removed the pre-muffler today. I couldn't see any resonators. Only the premuffler. THere is no diff. in sound at idle and there is no droning. THere may be a little but you can't hear anything above the raod noise. The exhaust does sound louder I'd say about 15% louder and and had a deeper tone to it. All in all very nice.
Also, after looking at the stock piping Nissan did a good job on the exuast. The sotck piping is pretty big about 2.5" which is pretty nominal for NA cars.
