Anyone run high-flow Cats to reduce hydrocarbon exhaust smell?

I apologize for not being more concise. The number 14..5 is rough average from memory. My portable wideband fluctuates from roughly 14.2 to 15.1 at idle. The voltage on my pre-cat O2 varies between .25 & .37 volts if memory serves.

I really need to hook my wideband back up to get a precise A/F ratio number.
