My 2000 ws6 sat for a week and driving it today seems to have a different tone and be louder. Has no cats, slp y-pipe, and elt cut-out. This morning I didn't notice it seemed the same, it seem to change while driving this afternoon had the music blasting then something changed turned the music off and that's when I felt it was diff, I could be crazy idk hahah I did close the cut-out and it was real quite all flowing out back so I don't think its a leak anyone hear or have any ideas?
