I just put headers and run a Black Widow race venom on my 16'. Probably more loud than you want, but doesn't sound to bad.

I don’t have the cat back but I do have the TR. If the black widow is to loud for your liking idk if you would like the R or TR. I’ve heard good thing about the cat back quality and ease of install but have never heard one in person and I believe they use a different muffler then just the stand alone ones

I personally do love the sound of my TR tho.
Shoot me a text I have a video of it if you want to hear

That mud flap is the first thing guys take off at the dealership I work at.
The flap is definitely removable. I'll decide after wheels and lowering if I'll remove it.

I took mine off and the body is like molded for it to fit there, looks like something is missing with it off.
