Shineray XY250GY-2 MX Exhaust Upgrade
There is alot of hp/kw to gain threw an aftermarket exhaust system. So being a China Moto this makes things very hard in this area.
So what i have done is bought a couple of exhaust pieces and im going to pass them and the bike onto my cousin who owns a car exhaust shop. (Im pretty lucky).
So what i did was take off the old exhaust.

Now i studied this for hours and came up with that this looks very much like a CRF450 front header like this.

I bought from ebay for $180.00 delivered.
I new my frame was a ktm type so i bit the bullet and bought a lexx tail pipe.

So by the end of the week it should be back together and finally a dyno run.

So the front header pipe needs cutting and shutting and the tail pipe needs a mid pipe that will get built and the tail pipe was $344 delivered.
