A lot quieter than straight piped but it helped with back pressure. Although the inside wasn't welded that great it still works like a charm.

Good resonator for 4 inch exhaust. Purchased in order to decrease "drone" at 60-70 mph. No install instructions with unit. I had to contact mbrp as their was no inlet or exit labeled and wasn't sure which was which.
