I used Kenny's muffler (I think that is the name) on 17a towards moncks corner where the four lanes go to two. He was pretty good price wise and quality. I tried to go to RC too but didn't have a good feeling. I have heard great things about them but I kind of got a run around. There is a guy on Trolley (maybe Bobs) that does good work but when I called him he said that if it came with cats he had to put them there.
