i wanna change my header of my civic dx into the vtec civic ex, and i want to kno wat i would need. ty to everyone who helps me.

 

My first step would be to make sure that they are the same bolt pattern on the head. I don't know **** about SOHC's so I couldn't tell you, and also if the DX has a o2 sensor in the manifold and the EX might not? I don't really know what I'm talking about here, I'm just guessing. Make sure they are the same lenghts also and hopefully it will bolt up to your stock cat.

 

should would fine. the bolt pattern on the head is the same.
