There are tons of cat backs that use the stock hanger locations. It is my personal opinion that those are a waste. I just want the sound without the extra parts. Neither are gonna improve performance, so why replace more than the muffler?

But these manufactuters want to make more money of course, so sell the kit only. Just looking for one that offers just the muffler w/o kit.
I was planning to just do the muffler only too, until I saw the hanger welded to the muffler itself. Ended up just doing a cat back system.

To everyone that writes they had a brand name muffler installed it is useless without the model name.

This is the only “muffler” replacement I know of for our F150s:

Magnaflow 19572

Otherwise it’s a full cat-back kit.

There is no true dual cat-back kit available, there are dual exit cat-back kits. The right catalytic converter joins the left before dumping into these “cat-back” kits, hence the name.

I do think you would see a performance improvement with one of the 4” dump kits available, but expect drone and obviously decibels.

Found this number 19572 on hottexhaust.com but could not find it on Magnaflow's site

I have decided on the Flowmaster dual exhaust with options for side or rear exit (717871) with the Super 40 muffler and dual wall tips (15363) $945.

stock pipe isn't 304 stainless, for some, that helps in the climate they are in. But, pretty much goes for anything aftermarket, they are in it to make money, and people that mod everything form tires, exhaust, stereo, leather seats, lighting, its all a cost .

But many do both, catback and mufflers. Options :)

Had a custom dual Magnaflow installed. Just right, sounds like a V8 should without being obnoxious. Had dual running out the back but, they set too low for me, so now have Wesdon dual slant/angled behind each wheeel and now I'm happy!
Next on my list....spoilers!
