About 6 mos ago I put Mac axel's on. Then because of the drone and the (drone from my hubby) I put resonators on, but took them off within 2 weeks. I still have my Macs; what I have noticed is the drone is less and as my daughter would put it my car doesn't sound as angry. The question:Is it normal for mufflers to decrease in sound, drone, vibration etc...after a period of time? If so, why?

Thank you in advance...

They do take some time to mellow. I have heard that Mac's do drone an awful lot though. I would think it is about the same as before though. My stingers sounded better after a couple hundred but the drone didnt change all that much.
