Ok so I bought a "slip-on" HMF ECO for my BF750....needless to say with the weather issues I didnt have a chance to install it until now. So now two months later I find the pipe doesnt fit the bike. The pipe from the rear cylinder to the pipe Y inlet is too short and the other side of the Y inlet is the wrong diameter....Has anyone else ran into this issue? Is it possible I have a pipe for a different bike by mistake?

Need help.
