Looking to see what everyone has done in either dual 2.5 or single 3. I'm looking basically for a shopping list of: buy X amount of X degree bends, a resonator X long will fit, etc. I'd rather buy all the bends then just take them to get welded up to avoid shop markup on parts. My old exhaust had a few too many/sharp bends in it for my liking and wasn't mandrel bent so I'm not looking to just replicate it

I used 6 45 degree bends in my exhaust. It was mostly because I couldn't accurately miter bends very well. If you're good at fab you can usually get two 45s from a 90, or four 45s from a 180 bend. However, this means you'd use more straight pipe and possibly have to weld a few more times. If you're good at fab, this means very little.
But, if you're a hacker like me, it sure helps to have material that you can screw up with.
I went with 3.5" pipe. I used a Magnaflow 14909 3.5 center in offset out 9x11x22 muffler and a Borla ProXS 40946 4.25x7.875x16 muffler as a resonator.
I used a modified Section 1 to route the exhaust to the center tunnel, where I merged it with a 2.125 into 3.5" y-merge to megaphone.
