I have MSDS headers and y-pipe, the stock cat, and trubendz nonresonated magnaflow catback exhaust. It is loud, but not so loud that I get pulled over. Flooring it the car sounds very loud and very mean. Highway cruising gets anoyying at speeds over 80mph, and I would not go for long drives if it werent for my loud stereo system. My GF thinks it is to loud and my car sounds grumpy. I like it, but I can see it being annoying to others. On a scale of 1 to 10(Ricer) I give it a 4. I have heard louder mustangs.
