Since the catalytic converter and muffler are missing on the F53, obviously i need to reinstall them.

I'd like to get a generic cat if cheaper, but i dont know how to size it.

I'm considering supercharging the engine (some day), so i'd like to take a holistic approach to the exhaust system. "Tuning" if you will.

1) how close to the Y do i want the cat?
2) what size tubing for proper throughput?
3) exhaust manifold recommendations.
4) i'd like an efficient muffler. One that is high[er] performance, but as quiet as possible.

you want the cat as close to the header as possible, you don't need any after the Y

single 3"

any long tubes that fit

vibrant ultra quiet resonator and flowmaster super delta 50

Install the resonator and the muffler?

yes if u want quiet peaceful no drone cruising

resonator goes up by the y

muffler goes before the rear axle

Resonator as close to the cat as possible?

nah on the other side of the y would be most fine unless you wanted to run two resonators which wouldn't be necessary.
