Default Cat Converter

Hi I was wondering the last converter on a MY99 LGT after the half moon one, What is it for as o2 sensors are on the first one.

I was going to just get a straight 2.5 piping from the first cat all the way to the muffler will this cause any problems and will I be able to gain anything after this?

if your 02 sensors are up and down of the first cat only you can shop out the second cat for straight pipe. It will be a little louder and flow better but if your first O2 sensor is in front of the first cat and the second is after the second cat you may need relocate the second sensor to the first cat
