Where do I find a stock header? I searched lifan exhaust and found these

The shape looks wrong

Here is an XR200

Here is an XT225 which I saw spud used on his bike...

Here's what I have



The weird header off my XR, below is a DR350 header...





It's weird how it looks like it's from 3 different pipes you can tell by the metal texture. The end is also useless because it gets bigger instead of smaller...



DR350 pipe



It won't fit inside like it should. I could cut it up more to fit but frankly with it leaking and being so crappy I think it's better to just find a new one.



DR350 fits in the head snugly but the bend is wrong.



Even if I somehow bent it, It's also pretty snug fit. It's hard to clear the clutch cable, the carb, and the frame.






This is the end of the DR350 header, it is 42mm outside. It fits snugly in the head of the 163FML. A 42mm end header with the right bend would work.

So right now I'm considering XT225, XR200, and a stock one? Where do I buy stock headers for this bike? Are there any other bikes that might work?

I think the XT225 header looks nice, I know that longer headers tend to build power at the top end in exchange for bottom end.

Thanks for continuing to help with my project.
