I don't have video of it revving or anything, but the 3" exhaust does get pretty obnoxious at WOT. However, the x-pipe & magnaflows keep the noise pretty subdued when just cruising around. I can easily listen to the radio or have a conversation without really trying.
I went flying by one of my friends wide open and he said stuff in his truck started rattling so....
About the only video I have of it running

Other than my pass at the track, but you can't really tell how loud the car is in this one
