stock cats are something stupid like 400cpi
the ones i'm using are only 200cpi, so they will flow a lot more for the same diameter.
But i'll step them up to 2" in/ out then into 2" collector
so there's going to be much less restriction than stock.
my tuner has indicated that there will be no issues
IIRC the front 02 sensor is the wideband and rear is just the generic narrow-band.
