I simply did it more for the sound and took into consideration cost. I had originally started with a resonator delete pipe and ran that for a few week and wasnt pleased with the grunt/engine rumble/etc. I ended up re-installing the resonator and had the muffler cut out and a piece of pipe the same diameter as stock tubing put in its place. I have not noticed any significant loss in low end power, but this is just 1 personal experience.

I'm considering taking the cheaper route myself but wondering for those of you that did the muffler delete did you keep the resonator or remove that also?

I just did this to my 13 5.0 no muffler resonator still
duals out the back
Sounds great no lights no loss of power
