dual nozzle upgrade question

[Turboaddict]

I have the stock single nozzle right now. I want to upgrade to dual nozzles. can i just get the extra smaller nozzle and leave the stock one in because since its welded(JB welded that is) i might as well leave it in?

Good question. I'm about to upgrade to dual nozzles. I just assumed I would get another uppipe and drill for the dual nozzle.
