Need Exhaust suggestions for 6.7 delete

I'm deleting my 6.7 next weekend. I have everything I need except for exhaust. I'd like a 5 inch turbo back system but don't want drone in the cab. I'd like it loud, but the drone sucks. Do I need a muffler, or will it not drone with the straight pipe?
Thanks!

I have a 4in Flo pro. Nice tone outside and zero interior drone. Flow through Flo pro muffler. My buddy had the same on his but it's 5in and way too loud with lots of drone. He wishes he went with 4in.
Good luck

Just add a resonator style muffler. Going to a 5 inch will make it drone, so stick with the 4 inch.

I added the 4040XL Aero Muffler and love it.

I have MBRP 5" from turbo back. It drones a bit, but I can control it being I have a manual transmission. I imagine its horrid with an automatic. I am torn but occasionally I wish I went with a 4".
