Im about to trade my stock header for a used good condition megan racing header, how much cash on top should i pay guys? 
Depends.
OEM manifolds are worth almost nothing. I wouldn't pay more than $20-30 on top.
Imo, the oem quality far surprass the megan header. I would just do a straight trade. Most likely you will need to replace the gasket and look for cracks on the welds.
In my opinion it's just a straight trade...i would get some gaskets from ur local shop and maybe get that orange sealant for exhaust...do a little around the gaskets and u'll good to go....dont get the coated ones thi, they crack!!
