I wouldn't mind removing the primary cat completely if it's only a mild increase in sound.
Does anyone know if a custom tune is necessary to get the best out of it or would you be ok with with something like a bms powerbox (which i have installed at the moment)

BMS Powerbox is what I am running right now too.
No need to worry, once you remove the cats you'll feel the difference.
