My neighbor is a complete Harley freak. If it doesn't say Harley he doesn't have it and of course he has straight pipes (so everyone will know he's on his Harley). He too a trip last year of about 600 miles one way and on the way back he left his ear plugs in the motel. When he got home he could barely hear so naturally I started talking real low to him. I tried to convince him to put the mufflers back on, to no avail. He got a new set of ear plugs now and carries a spare but still has the straight pipes! You just can't fix stupid!!
