New catalytic converters w pipes

[Machete]

Sooooo...turns out that rattling wasn’t coming from under the hood and the ac compressor.
The rattle is from both sides inside the cats.

Ordered a set of Walkers Direct Fit for both sides all 4 and pipe.

This ole gal owes me a few favors.

Installed Walker’s with pipes for both banks. Sounds great feels great.
How bad were they? So rusted the insides were rattling around and blocking gasses.

Could you feel the rattling beneath your feet under the floorboard? I installed new cats a couple of years ago and I think this is happening to my cats. It almost feels like a "grinding" noise coming from underneath when I'm in idle.

No it was a tin can rattling underneath engine compartment behind front tires up-in-der.
It was intermittent but started to increase. I thought it was the ac compressor but nope.

How do the Walker cats compare with OEM ones? I need to replace the drivers side one soon on my 2014 Limited. Ford wants about $800 for the part itself. Walker is about $500.
