i have a single cam vtech and i wanted to get cams i have stock internals headers intake and exhaust what stage should i get and does installing them do u feel any power change???GIMME SUGGESTIONS OF WHAT SHOULD I DO?

 

You have a single cam, but you want to know what cams, as in plural, to get?

Also, you can only have one header on your car, and Vtech makes phones.

To answer your question, I have no idea.
