so i know if i order the 06 GSF yosh trs slip on i will need to do something because the pipe diameter is larger then my 02 and so on......
my question is, has anyone done it? i have a pneumatic pipe expander at my disposal and im just wondering if there is any tips and tricks and what size i have to make it and where i need to cut the stock pipe. thanks for any help. pictures would be much appreciated!!!

this picture doesnt really help but here is the slip on:

If you got the yosh that is made for the gs than you just cut slip on clamp and be happy. If you got another bikes can that just expand the the end of the pipe so the I.d is the same as the gs o.d and that's it you can slot the pipe and clamp is on or tack weld it.

its that simple?

yoshi does still make a true slip on not a bolt on. the easyest thing to do would be go to ebay and get a mid pipe from a sport bike then get that fited to the bike and buy a bolt on for that flange

thats why im just buying a slip on.....

dennis kirk got both pipes for the gs craftierod
