1. I'll assume the mellon-shooter / 5inch cannon is the muffler you are using and not a 5inch diameter from the header back?

2. One thing about exhaust systems is that it works as a complete package, also the camshafts and a number of other parameters and aspects
need to be taken into consideration. Back pressure is very important, and what is desirible for a forced induction is not pragmatic for NA applications.

3. I would prefer you use a high flow cat, at least you would be more with in the letter of the law. Most circuits, speedways, and so on have sound regulations
and most professional series require all entires to be catalytic converter of some type. With all of that said a professionally made system with high flow cyatalist
will produce the same power as a unit without small loss maybe. You in the seat of your pants would't notice it.

4. All in All, here is what I recommend if you do not wish to use a catalist. Simply where the catalist is located, use a pipe that runs back to the muffler with the associated bends for clearences and diameter of the inlet of the mufflers diameter.

Good luck,
