Do these headers just bolt up or do they need welding? Please advise.

Thx!

They will bolt up fine. The only problem I had was from the Y pipe to the cat. I ended up having to weld it to the cat since the old Y pipe was a POS.

 

Welding will be required, no matter wich brand headers you pick. You gotta connect them to the Y-pipe or to the individual cats(Dual cat 3rdGends).
You can get away with clamps but I don't recomend them because it will sound like you have an exhaust leak, which it will actually be.
