Default LS400 Exhaust Setup

Hey guys I recently purchased a '99 Lexus LS400 and I'm planning to change out my exhaust but I'm having some trouble figuring out what size piping i should use which was why I was hoping anyone here could help me out. Im planning to cut my exhaust after my secondary cats and use a stainless steel piping all the way back with some 3, 4 or even 5 inch tips. I am planning to add an x pipe where the stock resonator would be to make a true dual. I would like a loud but deep tone. I was thinking 2.25 but others say 2.5 or 3 inch anything would help. Thanks in advance!

I looked at videos on YouTube and settled on the beefy sounding but not too loud of deleting the rear mufflers

Keep the prelim mufflers. Ditch the rear. My Celsior sounds brutal with this setup and 2.5 all the way through
