I got single exhaust now and I want to put duals on it so when I get my kit do I change my old muffler out with the new one ?

Welcome to 2CarPros.

I'm not sure what kit you are referring to. If it comes with new ones, then yes, they should be installed. There could be a difference in pipe diameter. Also, if you are going to dual exhaust, there should be two mufflers.

Let me know if you have other questions.

Welcome back:

I would say, yes. If that is what it came with, it should go right together for you. Otherwise, you may be trying to adapt the old muffler.
