Oh yeah...it gets loud....VERY LOUD. However, at 60 my truck is turning about 1700 RPM, and at 70 just a tick over 2100. It isn't bad at all, and I know what bad is. I had a 2006 that had true duals, with flowmasters and then magnapacks on it. I know what drone is, and this doesn't have much of it at all. You can lock the cruise in at 60 or 65 and not end up with ringing ears, but you do hear it.
It does have a odd fluttering or thrumming sound when you are lugging the engine...almost gets raspy...but deeper. Sounds mean as hell outside, especially on take off. You get it into the upper RPM band of 4500 + and it is just plain insane loud. I mean....cop attracting loud. It is a mix of raspy, deep, crackly, and everything in between. Just plain mean.
This is not the exhaust for someone that wants a quiet setup....not at all. However, I can say if you are easy, you can sneak into the neighborhood and not wake everyone up (my wife did it tonight). If you keep the revs below 2000 you aren't much louder than any other aftermarket system.
The other thing I noticed is that this system is a true 3" all the way through. The OEM resonator gets choked down to 2.75 or 2.5 at one point. In fact, I could slip the mid-pipe from the Roush system over the outside of the OEM resonator pipe.
