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.

I'm surprised it sounds ok. Z guys have done this and it sounded like crap.

You think you picked up any performance?

I don't feel anyperformance gains.


Actually, just got back from some spirited driving. The car literally SCREAMS like a banchee after 4K rpm. Has a loud schrilling raspy sounds kind of like the sound you hear form the Spoon race cars or NA aspirated full race cars. But sounds really good from idle to about 3.5Krpm
