It has some rust pin holes in it and will probably require some welding to repair it. The threaded part where it bolts up at the exhaust pipe has come loose and will require some work to repair. It has surface rust all over it. It is missing the removable tail pipe baffle. 

it is marked with yellow paint marker as a XR 250 but it is for a 1984 and 1985 XR200R.

It has the letters KKO embossed on the pipe which indicates it is for the 1984 and 1985 XR 200 R models.

Selling this one as is because it needs repair.
