It's definately louder than stock but sounds good. There is some noise in the cabin but not to the point of being annoying. There is also a little bit of a drone right around 2K RPMs but it's not loud enough to be unbearable or anything. When we did my stereo we did about 100 sq feet of Dynamat so that may be part of the reason that I don't have much noise. Stereo is about 1K watts so I don't hear outside noise from anything if I don't want to. It's hard to get a feel for how the exhausts sound from listening to them on a computer. It's best to try to find some people that have done exhaust upgrades and listen to them.
