I didn't do it yet. I'm seriously thinking about doing it though. do you like the way it sounds on yours?acuratls23 said:yes they can..did you keep the original resonators that they took off? they can cut off the replaceement piping and then put it back on. any muffler shop can do it I had mine done but only took out one of the resonators out. The guy said if it's too loud i can always have them put back on.
