Hey im trying to put on after market headers. and i cant get the stock ones off. i dont know what to do. i was wondering if i need there is hidden bolts under the whole heat shield. I dont know what to do, so plz givce me some advice on how to take the stock ones off.

 

1) its header not plural you have only one
2) heat shield must come off first
3) there are 9 bolts/nuts holding it to the head, one down lower in front, and 2 on back side of engine, and 2 on the cat holding it in place
