My magnaflow also got a lot louder after a certain amount of miles. I added a viberant resonator and it barely quieted it down. I mean it sounds nasty now but I don't want nasty all day every day. I have the 28 or 30 3 inch in and out. On the outlet it enlarges to 4 inch for the over axle and tail pipe.
