is there any way to change my stock exhausts sound?

i have a 323is. it has a stock exhaust on it. i would like to know if there was neways to make it louder/nicer without replacing it?

Well you could drill holes in your muffler but 96% of the time it sounds like crap i would just buy a new exhaust it is expensive but it is the best way to get a better sounding exhaust.
