Default C7 NPP Muffler outlet size

What is the OD size of the 4 x pipes coming out of the NPP Z06 mufflers? I want to put aftermarket tips on but need to confirm size of the small pipes that the tips connect to? Did google search but cant find the true OD. Thanks

I just finished this set up today. Considering making a slip on kit. The stock stuff just looks weak to me. Post up your set up when you get it done I am curious to see what you come up with.

2.5 inch inlet double walled 45* angled tips with 4 inch outlet. This is on a muffler delete set up, but the stock exhaust could be done the same way. I will post up a thread on it Friday when I get home from work and put up plenty of pics.
