ses codes

[akcamaro02]

i have read alot of websites about which cats will and wont throw codes, and what size cats do and don't..and ppl seem to contradict each other so what exactly size and type of cat will and won't throw a code for the rear o2..i want a high flow 3" in/2.5" out but will it throw a code..or is a 3"/3" better then just reduce it to 2.5"
