Muffler Delete, yes or no?

Cut the pipe in front of the muffler and behind the flapper. Drop in a piece of straight pipe, it’s a ten minute $10 fix. It doesn’t sound horrendous. It’s really not that big of a change. After a week, if you don’t appreciate it... two cuts and slip a muffler in its place. I like Aero mufflers, they’re easy and work well.  You’re not out anything by trying the straight pipe. With the three OEM resonators, it’s not a huge difference and it’s basically free to try.

I deleted the muffler and resonator on my 2018 5.3L and it sounds awesome.  Deep, aggressive...  I kept the CAT's and just had pipe welded in to replace the muffler, flap and resonator and put a tip on the end and called it a day.  Everyone comments on how great it sounds...
