Damn, I just bought this exhaust a month ago. This is a good deal since it's normally $500+ before shipping. Here's a video I made to show the sound of the exhaust under different circumstances. WOT happens at about 2:40 and 2:55, and there are some revs at the end. This is with a SPM catted, non-resonated downpipe.

This video gives a pretty good representation of the sound in real life, and if anything it makes it sound a little louder than it actually is. It is not a loud exhaust, in fact I bought it because it is considered one of the quietest catbacks you can get. I held off on getting a cat back for a while because I absolutely did not want anything loud or obnoxious. For an aftermarket exhaust, it is quite mild during normal driving. It has an audible but not loud rumble at idle and can just be heard over wind and road noise while cruising. I have not found any speed that causes drone. It gets noticeably louder under higher loads, but is never offensive. The sound at full throttle has a deeper tone than stock and is very clean with little or no rasp.
