im trying to get a two piece ss header, but it doesnt have the hardware to bolt the two pieces together, so im sure someone has had this issue before and i was looking for some input - im thinking i can use the hardware from my old gsr manifold, but w/o them in front of me, its just a guess - im trying to get this figured out b4 i get the header cus i dont want to have to wait to put it on, and i dont really want to use Home Depot hardware - tia, later

 

If the stock stuff doesn't fit, then I'd go with at least Grade 8 stuff just to be safe.

 

i know some people use slave bolts to mount the header on the head - is that the only option besides the stock studs/bolts - ive been looking but havent seen anything else
