Dropped off my 19 at MAGNAFLOW for prototyping. Will let you guys know what they come up with

New to the truck scene. Why would I have this done, what are the benefits and what is the approx. cost? Thank you.
I just spoke to my local exhaust shop. $80 to install my own muffler, which would most likely by a Magnaflow 12278. 3" inlet/dual 2.25" outlet to tie to each pipe. Most folks say the 18" length gives a nice tone. Not as loud as a 14" but has a more aggressive growl than a 22" or 24". Will post pics and vids after the work is done!

If you have the dual exhaust setup, 2018 and older its a 3" inlet and dual 2.5" outlets....2019 is 3" inlet 3"outlet then Y'sHi guys just got mine last week! 4X4 Crew Cab Big Horn in Graphite. So, just to do a factory muffler swap, it's a 3" in 2.5" single out, then it Y's after correct? Any idea what the individual pipe sizes are after the Y? Thinking I may try to do 1 in 2 out.
Actually, its a 3" in, single 3" out... Then downsizes to 2.5" after the "y"stock goes 3" into muffler and single 2.5" out with a Y down the pipe.
This setup has a 3" I let and dual 2.5" outlet.
