Mine resonates inside the car quite a bit around 70-75, but isn't bad other than that. It's louder than I would like but that's because I'm too silent-oriented. It's louder at idle and low speed cruising than simply replacing the stock muffler, but I really don't have anything else to compare it to as I went straight from a completely stock setup to 2.5" piping with a cat, Vibrant Ultra Quiet resonator, and Street Power muffler. I'll try to get a video Sunday of how it sounds. Keep in mind that I also have a BEAMS, so tone will be different compared to a 5S.
