well going about 70, you cruise at around 3k rpm.. it a steady sound and can get a little annoying if you keep the pedal down, but you can work with the pedal to make it not as loud and annoying when driving on the interstate.. when just doing normal driving it's pretty quiet and is just a nice low roar.. it gets a little higher pitched when you really punch on it and vtec kicks in.. but it's still a very nice sound
The silencer is a little hard to get out at first (it comes with it in).. you need to use a lot of wd40 and some plyers or something to wedge it out.. it's a tight fit. I never used mine though, I took mine out right before I put it on.
The Evo isn't really quiet.. but it is quiet. It is noticable, but not really loud like the n1 when you get on it.. It has a nice low rumble on the low end.. but gets higher pitched.. still has nice tone too it, though. But if you wanna hear your exhaust, and you want others to hear it too.. I do'nt really suggest this exhaust.
