have a 2009 CVO Roadglide. replaced only the head pipe with a non-cat one from e-bay. went to sturgins this year and was concerned with heat. went through jamie@fuel moto and did a pc-v... perfect. now trying to decide on just rinehart 4 inch slip ons or their true duals. Trailered there and back from Michigan, but rode 700 miles+ while there and also did iron mountain road. Felt good riding, no specs/dyno sheet. just had fun!
