Hi I’m new to the forum and a little history with bikes but not much. Would like to get my road licence soon. My Shineray dirt bike has a split manifold struggling to find the correct one with the right angle on it if anyone can help.

Bike is a Shineray with unknown engine side: engine code FMI156
