As soon as I purchased my BDM Chopper I went over to Martin Brothers the very next day and picked up the "Medustas". i had thought about taking off the baffles before installing them, but they are loud enough as is and sound wicked. I shoose those because i like the way it kind of twist over eachother and the way the tips are cut. Wife said the bike was loud enough when I brought her home and dosent much care for them, but she said I couldn't stop smiling after I installed them and turned her on. She was right, because I got turned on after hearing that chop.:up:
