hey can anyone offer any advice for removing the Greddy header and replacing the stock one? I'm gonna be doing this tomorrow early so should I warm up my car or not? Also if I have the old stock manifold gasket, can I use that one or should I go and get another one? If I have to use new bolts for the stock exhaust manifold, anyone know what size they are?tia

WAIT are you taking off some greddys and reinstalling the stock manifold?

its easy to remove the headers and put back the stock one on our cars. i would help if i had time and all. i would get a new exhaust manfiold gasket. you dont need new bolts unless you lose, break, etc the old ones. DO IT WITH THE CAR "COOL" dont warm it up that will just make it harder and all.
well good luck

i don't have the original bolts, the guy that put on my header lost them all. I just have the ones for the heat shield. I need your guys help quick, what size bolts do I ask for at NAPA, can I use the ones on the Greddy header or do those come with bolts just for the header?

yeah you can use the bolts that are on your car right now.
