Need Help on Exhaust stuff for 1995 civic.
 

So, I have a 1995 honda civic dx sedan, with an engine swap to the d16z6, It should still have the same stock exhaust that the dx has had, I'm looking to changing my muffler to a thrush glass pack from autozone, I've already changed the Cat to a high flow, now the last step for now is going to be this glass pack. But I don't know which one to get, size wise. Which glass pack should I get, the 2" Inner Diameter, or bigger, or what? I don't know the exact size of my exhaust pipes as it is, It should be stock, So, if any of you have ever changed it, and know the pipe size of the exhaust, please let me know, or if you know which size inner diameter glass pack I need, Someone said I need the 2" inner diameter/2" inner diameter one. If that's correct, please let me know. I have already bought it, and I'm just looking to make sure it's the correct one, if not, I have to return it, and get the correct size. Lol. Thanks for your time.
