Can I use S.S. headers 3 inch pipe, O2 sensors in similar situations, cherry bombs by thrush, but no cats?
You can get Magnaflow Hi-Flow cats, but modern cats aren't anything like the restrictive catalytic converters of 30 years ago. What year is this truck? Some have before and after cat O2 sensors, and removing cats will set off the check engine light.
I would just do headers and cat back. The truck isn't going to like not having the cats. I have this on my 06 f 150 https://www.ebay.com/itm/Ford-F150-...387013?hash=item2edb476d85:g:JjYAAOSwiCRUl5QG
