Added High Flow Cats vs Hollowed Cats, Is there a change in AFR?
I kept smelling gas on my car, and thought maybe my cats were not working right, so I purchased some thunderbolt 300 Cell ceramic cats to replace what I had. It turned out my cats were actually hollow. I've previously had my car tuned, and want to know if my afr might have changed, and if so, which way (Rich or Lean).
Anyone know?

Potentially add some back pressure, but shouldn't affect fuel trims
