damn near went deaf test driving a goober friend of the boss's e30 325ic with nothing but two cherry bombs side by side in the back (one for 3 cylinders) i put a short shifter in it and needed to rap it up a little to see if it worked good and with no ac and the windows down had my left ear ringing. i told that douche when he drove it by the shop to show off his new "performance" exhaust it's too ****ing loud and would get old in a week and miserable in two, in two weeks it was quieter it sounds cute at first but that wears off

I've read a few exhaust design articles and the difference between having a straight through pipe or a resonator is a factor in what causes the annoying coffee can sounding muffler. Straight through piping is better for say racing purposes but can cause the coffee can syndrome. Also the glass pack/pipe (fiberglass packed) resonator will do the same overtime. The fiberglass is heated and work hardens over time and will give the rattling coffee can sound also.
