depends very much on the pipes and who makes the baffles. off the shelf "quiet baffles" for say V&H wont do it

Man I hope I don't have that bad luck. I've got V&H 2-2 big radius and past loads of coppers over the last month but haven't been pulled up...I don't know why they aren't pulling me up

I pass Highway Patrol everyday and they leave me alone.Pipes are loud and thats the way I like it.
Too many fuckwits out there still learning to drive after 30 years. Got caught by a local bike fool last year, Who, I was told by another highway patrol guy,(Whos getting a HD soon) was sore on Harley Riders.
Nothing Really to do with rules. Got some standard pipes and did the Test though, thought my motor was going to pass out riding there, sounded like a Postie bike.
