I did a muffler delete on mine about a year ago. Best $70 I've spent on the truck so far

So you just took out the muffler so it is basically straight pipes correct?

It still has the cats and resonator, but it just a straight pipe after all that where the muffler was. Mine cost me a total of 20 bucks for the 3" pipe and I am a welder for a living so labor was free. Most muffler shop guys around here weld like Ray Charles and all my exhausts leaked on previous trucks. I sprayed it down with VHT header paint and it's holding up alright... I will have to touch it up in spring on the welds again.

Muffler delete here and very happy with the sound!

Exactly the same set up on my 2013 STX 5.0. I started with a resonator delete first and it was not quite the sound I wanted, so I re-installed that and had the muffler removed and a piece of pipe welded in.

Are there any performance gains from this?

Most likely there is no performance benefit to this mod. The stock muffler is a straight-through design as well, with some baffles running at 90 degrees to the straight section.

I can't say I notice a difference in power. Also that being said, I'm not picky like some people on this forum are that can notice a defect in a truck the size of a pencil tip... I assume the resonator is just like any other straight through design muffler. So I'm sure theres a minute difference from eliminating the muffler and opening it up a little more. Though adding a CAI and a tune will all help each other tie together.
