muffler fitment

[tuanle16]

hey all, i believe there is a rattling noise in my 02 exhaust system. however, i can't seem to locate the exact location. i am just going to start to replace parts, starting at the muffler. does anyone know what years will fit onto 02? i have an opportunity to put a 98 muffler on and believe it will fit. however, i also have the opportunity to put on 05 s-muffler for same price. but i was told by local dealer this will not fit. is that true? any help would be appreciated. or anyone have a muffler, please let me know. thanks.
