Went back to our colonist ways, give'em an inch and we'll take a mile (don't know what that is in mm and kilometers). I make my pipes for stock motors out of 1 1/2" od .065 wall (thats 16ga) thick tube. To make collars just get pipe thats 1 1/2" on the inside.
What are the collars outside diameter, how long are they and how far up the pipe are they?
If you could tell me that you'd save me the trouble of taking the bike apart again :) But I understand if you don't.
