LS3 Exhaust Question (Easy)
So I am pretty sure on my theory, without much research. But I have a LS3 with no resonators or mufflers (Muffler delete basically). Simply put, if I remove my rear cats how much louder/deeper sounding will the exhaust be compared to just muffler delete ? Also will removing the rear cats trip a CEL, since the order is front cat, o2, rear cats ?

You will throw a CEL as you have to have the rear o2s hooked up or deleted in a tune and they cannot be much farther down stream or they throw a delayed response code. If your replacing them on the pipe replacing it you still stand a chance of throwing a code...
And you will have trouble passing DEQ......
